Siddique, KHM, SP Loss, and D.Enneking. "Narbon bean (Vicia narbonensis L.): a promising grain legume for low rainfall areas of south-western Australia." Australian Journal of Experimental Agriculture 36, no.1 (1996): 53. http://dx.doi.org/10.1071/ea9960053.
Full textAbstract:
The phenology, growth, seed yield and yield components of a number of introduced narbon bean (Vicia narbonensis L.) accessions and F9 breeding lines were compared with faba bean (Vicia faba L. cv. Fiord) or field pea (Pisum sativum L. cv. Dundale) at 3 sites in 2 seasons. All narbon bean accessions had slow development, for example all accessions reached 50% flowering 9-35 days later than faba bean or field pea depending on the accession, site and season. Dry matter production near flowering ranged from 1.0 to 2.3 tlha and the growth of the best accessions was comparable with faba bean. In general, the accession ATC 60114 collected in the Beka'a Valley, Lebanon, produced the greatest seed yield across the sites and seasons (on average 1.52 t/ha). In 1993, the best narbon bean accession produced seed yields that ranged from 59% of the faba bean seed yield at the wettest site to 121% at the driest site. In the following year, one of the driest in decades, 6 accessions produced seed yields of more than 1.0 t/ha, similar to field pea. Seed yield was negatively correlated with days to flowering, podding and maturity, suggesting that yield could be improved by selecting for more rapid development. Most accessions retained the majority of their leaves at maturity, but showed some degree of pod shattering and a moderate level of lodging at maturity. Genotypic variation in all these characters was evident. Further selection and breeding, together with appropriate agronomic packages will improve the adaptation of narbon bean to mediterranean-type environments of southern Australia. However, the adoption of narbon bean in Australian agriculture will depend on its marketability and acceptance by the stockfeed industry, and its on-farm utility.

Full textAbstract:
Field trials were conducted in 2 seasons at 13 sites on neutral to alkaline soils in Western Australia, to compare the growth and seed yield of 6 winter grain legume species: field pea (Pisum sativum L.), chickpea (Cicer arietinum L.), faba bean (Vicia faba L.), lentil (Lens culinaris Medik), narrow leaf lupin (Lupinus angustifolius L.), albus lupin (L. albus). In a dry year (1991), overall site mean seed yield was highest for field pea (1.35 t/ha), then faba bean (1.22 t/ha) and narrow leaf lupin (0.85 t/ha). Chickpea, lentil line ILL5728, and albus lupin produced an average seed yield of 0.64 t/ha. Rainfall in 1992 was above average and seed yields of all species except field pea were higher than in 1991. Heavy rainfall in winter and spring caused transient waterlogging at several sites, affecting growth and seed yield of most species. Faba bean responded positively to the increase in rainfall and produced exceptional seed yields of >4 t/ha at 3 sites. Mean seed yield was highest for faba bean, at 2.87 t/ha, then narrow leaf lupin (1.19 t/ha), chickpea (1.1 t/ha), and field pea (1.0 t/ha). Field pea performed poorly at several sites due to its susceptibility to transient waterlogging and black spot disease (caused by Mycosphaerella pinoides). Albus lupin and lentil line ILL5728 produced similar seed yields (0.78 t/ha). Lentil cvv. Laird (1991) and Kye (1992) had low seed yields due to poor adaptation. Seed yield differences between species at various locations were not simply related to any soil chemical parameters or to depth to clay. On a calcareous soil of pH(CaC12) 8 at Dongara, the growth of narrow leaf lupin was severely affected and the crop failed. Days to flowering varied between species; faba bean was earliest to flower (76 days), then field pea. Faba bean and field pea (particularly in 1991) generally produced the most dry matter, both early and at final harvest. The relationship between seed yield and rainfall was complicated by transient waterlogging and fungal disease (e.g. black spot in field pea) at many sites. Seed yield was significantly positively related to final dry matter production but not to harvest index.

Evans,J. "An evaluation of potential Rhizobium inoculant strains used for pulse production in acidic soils of south-east Australia." Australian Journal of Experimental Agriculture 45, no.3 (2005): 257. http://dx.doi.org/10.1071/ea03129.
Full textAbstract:
Profitability of the pulse industry relies considerably on crop nitrogen fixation because this process supplies greater than 60% of pulse crop nitrogen. Therefore the industry requires the most efficient Rhizobium symbioses and effective inoculation management. Re-appraisal of the recommended inoculant strain for field pea, SU303, in south-east Australia, was warranted by field evidence that SU303 failed to maximise grain yield at sites in Western Australia. Re-appraisal of the inoculant strain for faba bean and lentil, WSM1274, was warranted because of anecdotal evidence from Western Australia of associated crop failures. In addition, a glasshouse study in Western Australia reported greater dry matter production by faba bean and lentil inoculated with strains other than WSM1274. This paper reports trials comparing potential inoculant strains for field pea and faba bean in soils of south-east Australia. Comparisons are based on efficiency for nitrogen fixation, survival on seed and survival in soil. Additionally, because the pulse industry lacked comprehensive information to assist decision making on the need for recurring inoculation, relevant investigation of this issue is also reported. The results of 3 field experiments for efficiency for nitrogen fixation, over mildly (pHCa 5.0) to strongly (pHCa 4.3) acidic soil in south-east Australia supported replacing SU303 as the commercial inoculant. The efficiency for nitrogen fixation of WSM1274 on faba bean was not found to be inferior to alternative strains. However, its capacity for survival on seed at temperatures of 15°C and above, over a wide range of relative humidity, and perhaps its capacity for survival in acidic soil, was inferior. This provided additional evidence to justify the replacement of this inoculant strain that was agreed to by a national steering committee in 2001, based on the Western Australia reports, the early experiments in this study and those of a collaborative study in Victoria. Alternative inoculant strains to SU303 and WSM1274 were identified in the current study. Temperature and relative humidity conditions suitable for maintaining inoculant viability with extended storage of inoculated field pea and faba bean are also discussed. A survey of rhizobia surviving in soil was used to determine the time scale of persistence of Rhizobium leguminosarum bv. viciae and Bradyrhizobium sp. (Lupinus) in soils of the south-east. It was concluded that in soils of pH (CaCl2) <5.1, inoculation of field pea and faba bean should be routinely practiced; none of the strains of R. leguminosarum bv. viciae tested showed ability for survival in strongly acidic soil sufficient to obviate seed inoculation. It was further concluded that the absence of a legume host for lupin rhizobia for 4 or more years would also warrant reintroducing inoculant of B. sp. (Lupinus).

Full textAbstract:
Seed (grain) yield responses of faba bean (Vicia faba L. cv. Fiord) to applications of fertiliser phosphorus (0, 5, 10, 20 and 40 kg P/ha as triple superphosphate) and zinc (0, 0.5, 1 and 2 kg Zn/ha as zinc oxide) were measured in 3 field experiments conducted in 1997 and 1998 on neutral to alkaline soils in south-western Australia. Additions of fertiliser phosphorus significantly (P<0.001) increased grain yields by about 50 and 100% in 2 experiments, but in the third experiment differences in grain yield due to applications of fertiliser phosphorus were not significant (P>0.05). Increases in grain yields due to zinc fertiliser were small (<10%) and were only significant (P<0.05) in 1 experiment. This suggests the 3 sites chosen had adequate soil zinc for grain production of faba bean. In 1 experiment the increase in grain yield due to addition of phosphorus fertiliser was due to an increase in the number of pods per plant; numbers of seed per pod and mean seed weight were unaffected by additions of phosphorus and zinc fertiliser. Adding phosphorus and zinc fertiliser increased concentrations of both elements in grain, but had no effect on the concentrations of other nutrient elements (N, K, S, Ca, Mg, Na, Cu, Mn, Fe) measured in grain. These findings support results of a previous study in Western Australia indicating that phosphorus is the major nutrient element deficiency for grain production of faba bean in neutral to alkaline soils.

Full textAbstract:
Sowing rate influences plant establishment, growth, seed yield, and the profitability of a crop. However, there is limited published information on the optimum sowing rate and plant density for faba bean in Australia. The response of the growth and seed yield of faba bean (cv. Fiord) to sowing rate (70-270 kg/ha) was examined in 19 field experiments conducted over 3 years in south-western Australia. The economic optimum plant density was estimated at each site by fitting an asymptotic model to the data and calculating the point where the cost of extra seed equalled the return from additional seed yield, allowing a 10% opportunity cost for the extra investment. On average across all sites and seasons, only 71% of the seeds sown emerged. Increasing sowing rate resulted in more dry matter production at first flower and at maturity, and at about half of the sites there was a small trend of reduced harvest index. In general, the mean number of seeds per pod (1·8-2·6) and mean seed weight (32-45 g/100 seeds) were unaffected by sowing rate. As sowing rate increased, the number of pods per plant (5-35) generally decreased, but this was compensated by the large plant population and more pods per unit area. The asymptotic models fitted to the seed yield data accounted for 15-81% of the variance. In 8 experiments, the models indicated that yield was continuing to increase substantially as sowing rate increased at the largest sowing rate treatment. The estimated optimum plant densities in these experiments were beyond the range of the data or had large standard errors and, hence, were excluded from any further consideration. Among the remaining 11 experiments, the estimated optimum plant densities varied from 31 to 63 plants/m2, with a mean of 45 plants/m2. This study demonstrates that targeting sowing rates greater than the current commercial practice for faba bean in southern Australia of 15-30 plants/m2 results in more yield and profit. Additional experiments are required with sowing rates in excess of 270 kg/ha to estimate accurately the optimum plant density for faba bean. Fungal diseases were either absent or controlled with fungicides in these experiments but the interactions between disease, time of sowing, and sowing rates also deserve further attention.

Full textAbstract:
Five grain legumes species, narrow-leafed lupin (Lupinus angustifolius L.), field pea (Pisum sativum L.), faba bean (Vicia faba L.), chickpea (Cicer arietinum L.), and yellow lupin (Lupinus luteus L.), were grown on 2 soil types, a red clay and red duplex soil, in the < 400 mm rainfall district of Western Australia. The study showed that chickpea, field pea and faba bean accumulated less cadmium (Cd) in dried shoots and grain than narrow-leafed lupin. Yellow lupin had Cd concentrations ~3 times higher in dried shoots and ~9 times higher in grain than narrow-leafed lupin. For both experiments, the ranking (lowest to highest) of mean Cd concentration (mg Cd/kg) in the grain was: chickpea (0.017) < field pea (0.024) = faba bean (0.024) < narrow-leafed lupin (0.033) < yellow lupin (0.300).

Full textAbstract:
Summary. A number of studies conducted in Western Australia have shown that faba bean has considerable potential as a pulse crop in the low to medium rainfall cropping regions (300–450 mm/year). However, its yield is variable and can be low in seasons when rainfall is less than average. Traits associated with the adaptation of 10 diverse faba bean genotypes to low rainfall, Mediterranean-type environments were evaluated at Merredin in south-western Australia over 2 contrasting seasons. Plant density was varied with seed size to ensure all genotypes achieved similar canopy development and dry matter production. Time to flowering appeared to be the most important trait influencing seed yield of faba bean in this environment. Seed yield was significantly correlated with time to 50% first flower in 1994 and 1995 (r2 = 0.61 and 0.82 respectively, P<0.01). In the dry 1994 season, rapid leaf area development in ACC286 allowed a greater absorption of photosynthetically active radiation resulting in more dry matter accumulation than other genotypes. ACC286 also had greater root length density at 20–30 cm depth compared with Icarus and the standard cultivar Fiord. There were no significant differences in total water use between the genotypes examined, although the pattern of water use varied markedly. The ratio of pre- to post-flowering water use was about 1:1 in the early flowering and high yielding ACC286 and 2.6 :1 for the late maturing, low yielding Icarus. Seed yield and harvest index were positively correlated with post-flowering water use (r2 = 0.75 and 0.71 respectively). Above-average rainfall in 1995 resulted in increased yield of all genotypes, particularly ACC286 which again produced the highest yields. Early flowering genotypes with rapid dry matter accumulation in the seedling stages (such as ACC286) could widen the adaptation of faba bean to low rainfall, Mediterranean-type environments and situations where sowing is delayed.

Full textAbstract:
A range of cool season grain legume species have shown considerable potential for soils unsuitable for the production of narrow-leafed lupin (Lupinus angustifolius L.) at limited sites in the Mediterranean-type environments of south-western Australia. In this study the adaptation of these grain legume species was compared by measuring crop phenology, growth, and yield in field experiments at a total of 36 sites over 3 seasons, with the aim of identifying species with suitable adaptation and seed yield for specific environments. The grain legumes examined appeared to fall into 3 categories: (i) field pea (Pisum sativum L.), faba bean (Vicia faba L.), common vetch (Vicia sativa L.), and narbon bean (Vicia narbonensis L.) clearly had superior seed yield to the other species over a wide number of sites and years across south-western Australia (mean 1.0–2.3 t/ha); (ii) albus lupin (Lupinus albus L.), desi chickpea (Cicer arietinum L.), and Lathyrus cicera, L. sativus, and L. ochrus produced seed yields of 1–1.3 t/ha; and (iii) red lentil (Lens culinaris L.), bitter vetch (Vicia ervilia), and kabuli chickpea (Cicer arietinum L.) generally produced the lowest yields (0.6–1.0 t/ha). There were clear species × environment interactions. At low-yielding sites (<1.4 t/ha), field pea was the highest yielding species, while faba bean often produced the highest seed yields under more favourable conditions at high yielding sites. Lentil, bitter vetch, Lathyrus spp., and desi chickpea showed average response to increasing mean site yield. Soil pH and clay content and rainfall were the environmental factors identified as the most important in determining seed yields. Soil pH and clay content appeared to be especially important in the adaptation of lentil, narbon bean, bitter vetch, and kabuli chickpea, with these species performing best in soils with pH >6.0 and clay contents >15%. Seed yields were positively correlated with dry matter production at maturity across a number of sites (r2 = 0.40, P < 0.01). Future improvements in seed yield of these species are likely to come from management practices that increase dry matter production such as increased plant density and early sowing, and through the development of genotypes with greater tolerance to low winter temperatures, and more rapid phenology, canopy development, and dry matter production than existing commercial cultivars.

Full textAbstract:
Phytoplasmas were found in 33 plant species that were not described as host plants in an earlier Australian survey. Plants displayed characteristic symptoms of little leaf, proliferation, and floral abnormalities. Restriction fragment length polymorphism analysis revealed 13 different restriction patterns. The majority of phytoplasmas showed a restriction pattern identical to that of either the tomato big bud (TBB) or sweet potato little leaf V4 (SPLL-V4) phytoplasma. Phytoplasmas from 6 plant species showed a restriction pattern similar to that of the pigeonpea little leaf (PLL) phytoplasma. One phytoplasma from garden bean displayed a restriction pattern identical to that found in papaya dieback and Australian grapevine yellows (AGY) phytoplasmas. Seven new restriction fragment patterns have been detected and sequence analysis of the 16S/23S spacer region revealed that 3 of these phytoplasmas are related to the faba bean phyllody (FBP) group. The spacer region of a graminaceous phytoplasma was most similar to phytoplasmas from the sugarcane white leaf group. Another graminaceous phytoplasma was identical to a phytoplasma from Indonesia. The spacer region of a phytoplasma from poinsettia (PoiBI) was identical to the western X-disease phytoplasma from North America and Europe. The spacer region of a phytoplasma in stylosanthes contained no tRNAIle. Full-length 16S rRNA gene sequences from selected new phytoplasmas were determined to corroborate results obtained from the spacer region analyses. Three of these phytoplasmas (galactia little leaf, vigna little leaf, and stylosanthes little leaf) are, along with the PoiBI phytoplasma and the graminaceous phytoplasmas, members of phytoplasma groups that have not been reported before in Australia.

"Responses of faba bean (Vicia faba L.) to sowing rate in south-western Australia II Canopy development, radiation absorption and dry matter partitioning." Australian Journal of Agricultural Research 49, no.6 (1998): 999. http://dx.doi.org/10.1071/a98003.
Full textAbstract:
Sowing rate influences plant density, canopy development, radiation absorption, dry matter production and its partitioning, and seed yield. The canopy development, radiation interception, and dry matter partitioning of faba bean (cv. Fiord) were examined using 6 sowing rate treatments from 70 to 270 kg/ha in field experiments conducted over 3 years at Northam as part of a larger investigation of sowing rate responses in faba bean in south-western Australia. High sowing rates resulted in significantly earlier canopy closure, larger green area indexes, more radiation absorption, more dry matter accumulation particularly during the early vegetative stages, and greater seed yield than treatments where a low plant density was established. The results suggest that further increases in canopy development, radiation absorption, dry matter accumulation, and seed yield are possible by using sowing rates in excess of 270 kg/ha. The rate of node appearance was relatively constant within and across seasons (1 every 65·9 degree-days), whereas the number of branches per plant declined with increasing plant density, and less branches survived through to maturity at high density. The peak photosynthetically active radiation absorption (75-85%) measured at green area index of 2·9-3·8 in the highest sowing rate treatment in this study is similar to previous reports for other crops. The estimated radiation use efflciency (1·30 g/MJ) was constant across sowing rate treatments and seasons. High sowing rates produced tall crops with the lowest pods further from the soil surface than those at low plant density, and hence, mechanical harvesting was easier. The growth of individual plants may have been limited by the low growing season rainfall (266-441 mm) and/or low soil pH (5·0 in CaCl2) at the site, and competition between plants for radiation was probably small even at the highest sowing rate. Early canopy closure and greater dry matter production with high sowing rates may also cause greater suppression of weeds and aphids.

Full textAbstract:
Experimental plots of cool season crop legumes growing at diverse locations in Western Australia were inspected for plants with suspect virus symptoms over 4 growing seasons (1994, 1997, 1998, 1999), and plant samples were tested for infection with alfalfa mosaic (AMV), bean yellow mosaic (BYMV), cucumber mosaic (CMV), and pea seed-borne mosaic (PSbMV) viruses. All 4 viruses were detected in faba bean (Vicia faba); BYMV, CMV, and PSbMV in field pea (Pisum sativum); AMV, CMV, and PSbMV in lentil (Lens culinaris); and AMV and CMV in chickpea (Cicer arietinum). Among minor crop species, AMV, BYMV, and CMV were found in narbon bean (V. narbonensis) and grass pea (Lathyrus sativus); BYMV and CMV in dwarf chickling (L. cicera); BYMV in bitter vetch (V. e r v i l i a ) and L. clymenum; and AMV in fenugreek (Trigonella foenum-graecum). Incidences of individual viruses varied widely from site to site but plot infection sometimes reached 100%. Symptom severity varied widely with virus–crop combination. In large-scale surveys of commercial crops of field pea and faba bean over 2 (1998, 1999) and 3 (1994, 1998, 1999) growing seasons, respectively, randomly collected samples from each crop were tested for presence of AMV, BYMV, CMV, and PSbMV. In 1999 they were also tested for beet western yellows virus (BWYV). All 5 viruses were detected in both species. BWYV was found in 35% of faba bean and 56% of the field pea crops sampled in 1999, with incidences of infection in individual crops up to 40% and 49%, respectively. PSbMV was found in 42% and BYMV in 18% of field pea crops in 1999. In individual crops, highest infection incidences of BYMV and PSbMV detected were 31% for BYMV in faba bean in 1998 and 9% for PSbMV in field pea in 1999. CMV and AMV incidences in both species never exceeded 7% of crops or 4% of plants within individual crops. Infection by 2 different viruses within individual crops was common, even 3 were sometimes found. Cultivars infected with most viruses were Fiesta and Fiord for faba bean, and Dundale, Laura, and Magnet for field pea. BYMV was detected in the crop tested of dwarf chickling. In tests on seed samples from Western Australia of 30 commercial seed stocks of field pea, 11 of faba bean, and 50 of chickpea, PSbMV was detected in 11, 1, and 1, respectively; CMV in 1, 1, and 3; BYMV in 3, 1, and 0; and AMV in 0, 0, and 1. This appears to be the first record of seed transmission of CMV in pea and faba bean. Seed samples from Victoria were also found to contain viruses: PSbMV in pea and AMV in lentil. Widespread infection with viruses in evaluation plots and commercial crops of cool season crop legumes is a cause for concern, especially where individual crop incidences are high and 2 or more viruses are present. Sowing of infected seed stocks leads to introduction of randomly dispersed sources of virus infection within the crop sown, resulting in spread of infection and yield losses. Appropriate control measures are discussed.

"Effect of site, harvesting stage, and genotype on environmental staining in faba bean (Vicia faba L.)." Australian Journal of Agricultural Research 59, no.4 (2008): 365. http://dx.doi.org/10.1071/ar07150.
Full textAbstract:
Seed discoloration due to environmental staining in faba bean leads to poor quality and reduced market price. Environmental staining in faba bean is characterised by a dark brown, grey, or black discoloration of the seed coat at harvest. Its cause is unknown, but it does not appear to be caused by a pathogen. Environmental conditions during pod and seed formation and at maturity are thought to have a large effect on the degree of environmental staining. To test the hypothesis that seeds formed under stressful conditions will have a higher degree of staining, faba bean seeds were harvested at 2 different stages of maturity from trials located in a range of environmental conditions under a Mediterranean-type climate of south-western Australia over 2 seasons. Four faba bean varieties were studied (Fiord, Fiesta, Ascot, and Cairo). The majority of seeds had good colour but across the trials, 3–25% were stained up to an unacceptable level and this varied with location and variety. Seeds formed later in plant development (located on the upper nodes of the plant) had more staining than seeds formed earlier (located on the lower nodes). Seeds formed on small and weak plants had more staining than seeds formed on normal sized healthy plants. Fiord showed a greater amount of staining than Ascot, Fiesta, and Cairo when grown in the mild, southern environments. Early harvesting (at physiological maturity) did not reduce environmental seed staining compared with harvesting at full maturity. Chemical analysis of seed testa and cotyledons revealed that total phenolic contents of the testa and cotyledons increased with staining. An increase in Zn and Na and a decrease in K concentration in the testa were also associated with increased staining levels.

Full textAbstract:
Faba bean (Vicia faba L.) is a significant rotation crop in northern New South Wales. However, drought limits yield, and the reproductive structures of faba bean are sensitive to high temperatures and frost. Although early sowing can avoid terminal heat and drought stresses, the accumulation of large amounts of vegetative biomass may result in low yield. Experiments were conducted over 2 years at Breeza and Narrabri in north-western New South Wales, Australia, to examine the influence of sowing time on yield, yield components, maturity, pod distribution and biomass production. The second sowing date (early May) produced the highest yield and seed weight at both sites. However, the third sowing date (late May) produced greater yield than the first (mid-April) at Breeza, and this was associated with very high final biomass. At Narrabri, the first and third sowing dates produced similar low yield. Poorer yield in late-sown materials was likely due to terminal stress, and the impact will be greater in less favourable locations and seasons. The poorer yield of faba bean from the first sowing date was likely driven by excessive biomass accumulation, an effect that would be exacerbated in favourable seasons and locations. The lower seed weight observed at Breeza was possibly a result of greater intra-plant competition. The earliest maturing genotype had the highest yield and seed weight at both sites, indicating the importance of rapid pod growth and senescence in these warm and often water-limited environments. Dry matter production was greater with early sowing, higher moisture and warmer temperatures. In contrast to other studies, a weak relationship between biomass and yield was observed.

Full textAbstract:
Farmers in Mediterranean-type environments should plant annual crops as early as possible to maximise yield. Greater rainfall variability at the start of the growing season potentially exposes early-sown crops to water deficit, which may be severe enough to cause crop mortality or to reduce potential productivity. This paper shows that in a typical Mediterranean-type environment at Merredin, Western Australia, much longer dry periods between rainfall events are likely in April rather than in May or June, but with a sowing rule based on farmer behaviour the likelihood of damaging water deficit is small. Soil water at sowing is a good indicator of this likelihood. The implications of early water deficit for crop productivity were investigated for faba bean in two experiments at Merredin in 1997 and 1998. In 1997 simulated plant available water in the top 40 cm (PAW40) at sowing was 24 mm and 8-week-old plants displayed severe wilting after 6 weeks without rain. There was no crop mortality even after 8 weeks without rain and plants recovered quickly when rewatered. Water deficit reduced grain yield through lower evapotranspiration since withholding water reduced total supply but also because severely stressed plants could not extract water from as deep in the soil as less stressed plants. In 1998 simulated PAW40 at sowing was 41 mm and no wilting was observed when water was withheld for 8 weeks. Apparent transpiration efficiency was not affected by mild water deficit in either year, but was reduced by 35% by delaying sowing in 1998. This was due to higher atmospheric vapour pressure deficit during reproductive growth of the later-sown crop. These results suggest that delaying sowing in faba bean is more likely to reduce faba bean grain yield unless there is a strong likelihood of severe water deficit soon after sowing. This likelihood can be judged from the amount of soil water at sowing.

Full textAbstract:
The Better Fertiliser Decision for Crops (BFDC) National Database holds historic data for 356 potassium (K) fertiliser rate experiments (431 treatment series) for different rain-fed grain crops and soil types across Australia. Bicarbonate-extractable K (Colwell soil-test K) is the most extensively used soil test reported in the database. Data are available for several crop species grown on a range of soil types from all states except Tasmania. Species represented and number of treatment series in the database are: wheat (Triticum aestivum L.), 254; barley (Hordeum vulgare L.), 5; canola (Brassica napus L.), 130; lupin (Lupinus angustifolius L.), 32; sunflower (Helianthus annuus L.), 10; sorghum (Sorghum bicolor L.), 5; and faba bean (Vicia faba L.), 2. About 77% of the available soil-test K (STK) data on wheat, canola, and lupin are from Western Australia. The usual sampling depth of 0–10 cm is recorded for all treatment series within the database, while 68% of experiments have STK information from other soil horizons down the profile, usually in 10-cm increments. The BFDC Interrogator, a comprehensive data search and calibration support tool developed for use with the BFDC National Database, was used to examine STK–yield relationships for each crop across Australia, with more detailed analysis by state/region and then by soil type if data were available. The BFDC Interrogator was used to determine a critical STK concentration to achieve 90% of the maximum relative yield (90%RY) for each crop species, with a critical range (determined by the 70% confidence limit for the 90%RY) also reported. The STK for 90%RY for wheat was 40–41 mg/kg on Tenosols and Chromosols, ~49 mg/kg on Kandosols, and ~64 mg/kg on Brown Ferrosols. There was some evidence of critical values increasing with increasing crop yield and on soils with no acidity constraints to root growth, with effects presumably driven by increased crop K demand. The STK for 90%RY for canola, grown mainly on Tenosols, was similar to that for wheat, ranging from 43 to 46 mg K/kg, but for lupin, also grown mainly on Tenosols, the STK for 90%RY was a relatively low ~25 mg K/kg. Data for sunflower were limited and the STK for 90%RY was poorly defined. A comparison of critical STK concentrations for different crops grown on Tenosols suggested that critical ranges for 90%RY of lupin (22–27 mg K/kg) were significantly lower than that for wheat (32–52 mg K/kg) and canola (44–49 mg K/kg). Critical STK values were not determined for sorghum and faba bean.

Full textAbstract:
The removal of nitrogen (N) in grain cereal and canola crops in Australia exceeds 0.3 million t N/year and is increasing with improvements in average crop yields. Although N fertiliser applications to cereals are also rising, N2-fixing legumes still play a pivotal role through inputs of biologically fixed N in crop and pasture systems. This review collates Australian data on the effects of grain legume N2 fixation, the net N balance of legume cropping, summarises trends in the soil N balance in grain legume–cereal rotations, and evaluates the direct contribution of grain legume stubble and root N to wheat production in southern Australia. The net effect of grain legume N2 fixation on the soil N balance, i.e. the difference between fixed N and N harvested in legume grain (Nadd) ranges widely, viz. lupin –29–247 kg N/ha (mean 80), pea –46–181 kg N/ha (mean 40), chickpea –67–102 kg N/ha (mean 6), and faba bean 8–271 kg N/ha (mean 113). Nadd is found to be related to the amount (Nfix) and proportion (Pfix) of crop N derived from N2 fixation, but not to legume grain yield (GY). When Nfix exceeded 30 (lupin), 39 (pea) and 49 (chickpea) kg N/ha the N balance was frequently positive, averaging 0.60 kg N/kg of N fixed. Since Nfix increased with shoot dry matter (SDM) (21 kg N fixed/t SDM; pea and lupin) and Pfix (pea, lupin and chickpea), increases in SDM and Pfix usually increased the legume’s effect on soil N balance. Additive effects of SDM, Pfix and GY explained most (R2 = 0.87) of the variation in Nadd. Using crop-specific models based on these parameters the average effects of grain legumes on soil N balance across Australia were estimated to be 88 (lupin), 44 (pea) and 18 (chickpea) kg N/ha. Values of Nadd for the combined legumes were 47 kg N/ha in south-eastern Australia and 90 kg N/ha in south-western Australia. The average net N input from lupin crops was estimated to increase from 61 to 79 kg N/ha as annual rainfall rose from 445 to 627 mm across 3 shires in the south-east. The comparative average input from pea was 37 to 47 kg N/ha with least input in the higher rainfall shires. When the effects of legumes on soil N balance in south-eastern Australia were compared with average amounts of N removed in wheat grain, pea–wheat (1:1) sequences were considered less sustainable for N than lupin–wheat (1:1) sequences, while in south-western Australia the latter were considered sustainable. Nitrogen mineralised from lupin residues was estimated to contribute 40% of the N in the average grain yield of a following wheat crop, and that from pea residues, 15–30%; respectively, about 25 and 15 kg N/ha. Therefore, it was concluded that the majority of wheat N must be obtained from pre-existing soil sources. As the amounts above represented only 25–35% of the total N added to soil by grain legumes, the residual amount of N in legume residues is likely to be important in sustaining those pre-existing soil sources of N.

Commercial crops of faba beans (Vicia faba L.) in South Australia and western Victoria were surveyed for flower visitors and incidence of pollination. Honeybees were the only pollen vectors. The incidence of pollination was never less than 50% and averaged 80%. The effectiveness of honeybees as pollen vectors contrasts with their ineffectiveness in colder climates, partly because in the Mediterranean climate beans flower in late winter and early spring when bees are in search of pollen. It is unlikely that growers of faba beans in Australia will need to provide supplementary hives to ensure adequate pollination.

Full textAbstract:
Many cotton growers sow rotation crops after irrigated cotton (Gossypium hirsutum L.), assuming that they will improve soil quality and maintain profitability of cotton. Wheat (Triticum aestivum L.) is the most common rotation crop, although more recently, legumes such as faba bean (Vicia Faba L.) and chickpea (Cicer arietinum L.) have come into favour. This paper reports data on soil quality (organic C, nitrate-N, soil structure), yield (cotton lint and rotation crop grain yield, fibre quality), economic returns (gross margins/ha, gross margins/ML irrigation water), and management constraints from an experiment conducted from 1993 to 1998 near Wee Waa, north-western New South Wales, Australia. The soil is a medium-fine, self-mulching, grey Vertosol. The cropping sequences used were cotton followed by N-fertilised wheat (urea at 140 kg N/ha in 1993; 120 kg N/ha thereafter), unfertilised wheat, and unfertilised grain legumes (chickpea in 1993; faba bean thereafter), which were either harvested or the grain incorporated during land preparation. Soil organic C in the 0—0.6 m depth was not affected by the rotation crop, although variations occurred between times of sampling. Regression analysis indicated that there had been no net gain or loss of organic C between June 1993 and October 1998. Sowing leguminous rotation crops increased nitrate-N values. A net increase in root-zone nitrate-N reserves occurred with time (from June 1993 to October 1998) with all rotation crops. Soil compaction (measured as specific volume of oven-dried soil) was lower with wheat by October 1998. A net decrease in soil compaction occurred in the surface 0.15 m with all rotation crops between 1993 and 1998, whereas it increased in the 0.15–0.60 m depth. Cotton lint yield and quality, and gross margins/ha and gross margins/ML, were always higher where wheat was sown, with highest gross margins occurring when N fertiliser was applied. Applying N fertiliser to wheat did not significantly increase cotton lint yield and fibre quality, but increased gross margins of the cotton–wheat sequence due to higher wheat yield and protein percentage. Lint yield and fibre quality were decreased by sowing leguminous rotation crops. Management constraints such as lack of effective herbicides, insect damage, harvesting damage, and availability of suitable marketing options were greater with legumes than with wheat. Overall, wheat was a better rotation crop than grain legumes for irrigated cotton.

Full textAbstract:
Australian cropping systems are dominated by winter cereals; however, grain legumes, oilseeds and summer cereals play an important role as break crops. Inputs of phosphorus (P) fertiliser account for a significant proportion of farm expenditure on crop nutrition, so effective fertiliser-use guidelines are essential. A national database (BFDC National Database) of field experiments examining yield responses to P fertiliser application has been established. This paper reports the results of interrogating that database using a web application (BFDC Interrogator) to develop calibration relationships between soil P test (0–10 cm depth; Colwell NaHCO3 extraction) and relative grain yield. Relationships have been developed for all available data for each crop species, as well as for subsets of those data derived by filtering processes based on experiment quality, presence of abiotic or biotic stressors, P fertiliser placement strategy and subsurface P status. The available dataset contains >730 entries but is dominated by data for lupin (Lupinus angustifolius; 62% of all P experiments) from the south-west of Western Australia. The number of treatment series able to be analysed for other crop species was quite small (<50–60 treatment series) and available data were sometimes from geographic regions or soil types no longer reflective of current production. There is a need for research to improve information on P fertiliser use for key species of grain legumes [faba bean (Vicia faba), lentil (Lens culinaris), chickpea (Cicer arietinum)], oilseeds [canola (Brassica napus), soybean (Glycine max)] and summer cereals [sorghum (Sorghum bicolor), maize (Zea mays)] in soils and farming systems reflecting current production. Interrogations highlighted the importance of quantifying subsurface P reserves to predict P fertiliser response, with consistently higher 0–10 cm soil test values required to achieve 90% maximum yield (CV90) when subsurface P was low (<5 mg P/kg). This was recorded for lupin, canola and wheat (Triticum aestivum). Crops grown on soils with subsurface P >5 mg/kg consistently produced higher relative yields than expected on the basis of a 0–10 cm soil test. The lupin dataset illustrated the impact of improving crop yield potentials (through more effective P-fertiliser placement) on critical soil test values. The higher yield potentials arising from placement of P-fertiliser bands deeper in the soil profile resulted in significantly higher CV90 values than for crops grown on the same sites but using less effective (shallower) P placement. This is consistent with deeper bands providing an increased and more accessible volume of profile P enrichment and supports the observation of the importance of crop P supply from soil layers deeper than 0–10 cm. Soil P requirements for different species were benchmarked against values determined for wheat or barley (Hordeum vulgare) grown in the same regions and/or soil types as a way of extrapolating available data for less researched species. This approach suggested most species had CV90 values and ranges similar to winter cereals, with evidence of different soil P requirements in only peanut (Arachis hypogaea – much lower) and field pea (Pisum sativum – slightly higher). Unfortunately, sorghum data were so limited that benchmarking against wheat was inconclusive.

Full textAbstract:
Narbon bean (Vicia narbonensis L.) shows promise as a fodder, green manure and grain crop in south-western Australia. This study examines the effect of time of sowing (2 experiments), plant density (3 experiments) and reaction to herbicides (4 experiments on tolerance to herbicides and 1 experiment on removing narbon bean from a wheat crop) in 10 separate field experiments sown at 4 locations in the mallee region of Western Australia from 1998 to 2001. Narbon bean was found to be unresponsive to changes in sowing date with yield maintained until the first week of June. The optimum plant density (90% of fitted maximum) for seed yield was found to be 31 plants/m2, equivalent to sowing rates in the range of 75–100 kg/ha. A wide range of herbicides applied either before sowing or immediately after sowing and before emergence had no significant effect on grain yield. These included simazine (750 g a.i./ha), cyanazine (1.25 kg a.i./ha) and diuron (500 g a.i./ha), which were applied immediately before sowing, and imazethapyr (29 g a.i./ha), which was applied after sowing, before emergence. Diflufenican (75 g a.i./ha) was found to be the only available option for post-emergence control of broadleaf weeds. The use of the non-selective herbicides glyphosate (450 g a.i./L) and Sprayseed 250 (paraquat 135 g a.i./L and diquat 115 g a.i./L) as post-emergence herbicides was found to be unpredictable at a range of application rates. Results ranged from a yield loss of 47% to a yield increase of 23%. In an experiment to test a range of herbicides for the selective control of narbon bean within a wheat crop, numerous herbicides were found to effectively remove volunteer narbon bean indicating that narbon bean is unlikely to become a weed in most cereal cropping systems.

Full textAbstract:
Lupin is the major break crop used by farmers in Western Australia but neither lupin nor wheat uses much water from the B horizon of the widespread duplex soils. This study investigated the productivity and water use of a range of crops and pastures during 2 seasons on a shallow duplex soil, with a sandy layer 30-40 cm deep, at East Beverley, WA. The aims of the work were to evaluate the crops as alternative break crops to lupin on these soils, and to establish whether roots could proliferate in the clay layer, promoting both water extraction from the subsoil by that crop and improving yields of subsequent wheat crops. During the winter of the first season, a perched watertable developed for almost 3 months and some crops (especially lentil) grew poorly. Yields in the second season were generally good (lupin was close to the calculated potential yield and canola and Indian mustard were >2 t/ha), establishing that successful crops of oilseeds and grain legumes can be grown on this soil provided that there is adequate water without topsoil waterlogging. Yields of subsequent wheat crops were largest when following legume crops (40% in one season and 135% in the second compared with wheat following wheat or barley) but were also significantly greater following oilseeds (22% and 102%). Roots of cereals and pastures reached 80 cm in both seasons, whereas those of the oilseeds reached 60-80 cm depending on crop and season. Rooting depth of legumes varied from 70-80 cm for field pea to 30-50 cm for chickpea and faba bean, with lupin extending to 60 cm in both seasons. As with shoot mass, root mass differed between seasons, although on average, in mid September cereals and oilseeds had a smaller proportion (0·12 and 0·14) of total mass below ground than the legumes (0·24) and pasture species (0·18). Only a few millimetres of water was extracted from the subsoil by any crop in either season and there was no evidence that tap-rooted legumes or oilseeds were better able than other crops either to exploit subsoil water for their own use or to create pores that subsequent wheat crops might exploit.

Full textAbstract:
The occurrence and distribution of Pythium spp. were determined by collecting isolates of Pythium from common bean (Phaseolus vulgaris) plants showing root or hypocotyl disease symptoms from different areas of Western Australia in 2012. Eight different Pythium species (Pythium conidiophorum, P. diclinum, P. intermedium, P. irregulare, P. lutarium, P. mamillatum, P. pachycaule, and P. perplexum) were isolated and identified according to molecular sequences. P. irregulare was the most widespread Pythium sp. All species, except P. perplexum, were pathogenic to the hypocotyl and root of common bean. We believe this is the first report of P. intermedium as a pathogen on common bean worldwide. This is also the first report of P. conidiophorum, P. intermedium, P. lutarium, P. mamillatum, P. pachycaule, and P. diclinum as pathogens on common bean in Australia and the first report of P. irregulare as a pathogen on common bean in Western Australia. P. intermedium was the most pathogenic species, causing the most severe disease on ‘Gourmet Delight’ (percent root disease index [%RDI] 75 ± 2.9 and percent hypocotyl disease index [%HDI] 59.2 ± 3.2) and ‘Pioneer’ (%RDI 75 ± 2.9 and %HDI 65.8 ± 3.2). That the relative susceptibility or resistance (the ability of a plant to reduce the extent of invasion by the pathogen) of a given bean variety to one Pythium sp. was, in general, similar across the other Pythium spp. was an important finding, because this opens up opportunities to utilize a single virulent isolate of one Pythium sp. to identify general resistance to a wider spectrum of Pythium spp.

Full textAbstract:
In the mid 2000s subterranean clover (Trifolium subterraneum) seed producers in South Australia reported symptoms of a red-leaf disease in fields with reduced seed yields. The red-leaf symptoms resembled those caused by several clover-infecting viruses. A set of molecular diagnostic tools were developed for the following viruses which are known to infect subterranean clover: Alfalfa mosaic virus; Bean leafroll virus (BLRV); Beet western yellows virus; Bean yellow mosaic virus; Cucumber mosaic virus; Pea seed-borne mosaic virus; Soybean dwarf virus and Subterranean clover stunt virus. Surveys of subterranean clover seed production fields in 2008 in the south-east of South Australia and western Victoria identified Bean leafroll virus, Alfalfa mosaic virus and Cucumber mosaic virus as present, with BLRV the most widespread. Surveys of pasture seed production fields and pasture evaluation trials in 2009 confirmed that BLRV was widespread. This result will allow seed producers to determine whether control measures directed against BLRV will overcome their seed losses. Bluegreen aphid (Acyrthosiphon kondoi) was implicated as a potential vector of BLRV because it was observed to be colonising lucerne plants adjacent to subterranean clover seed production paddocks with BLRV, and in a glasshouse trial it transmitted BLRV from an infected lucerne plant to subterranean clover in a persistent manner.

The Tasmanian DAS-ELISA system was used to confirm the presence of BWYV in a range of plant species from the southern mainland states of Australia, from the North Island of New Zealand and from central Mexico. Leaf tissue containing BWYV remained serologically reactive for long periods after the tissue was desiccated either by freeze-drying, air-drying or drying over silica gel. Bean leaf roll, potato leaf roll and soybean dwarf viruses were clearly distinct from BWYV and from each other in DAS-ELISA.

Full textAbstract:
Abstract The stem and bulb nematode, Ditylenchus dipsaci, is a serious pest of forage, horticultural and other crops. The two races of D. dipsaci that occur in Australia are the oat and lucerne races. These two races have the 'normal' morphology compared to the 'giant' type that attacks Vicia faba. The oat and lucerne races have been found in eastern Australia but not in Western Australia. There are no morphological or specific molecular tests to differentiate races within closely related 'normal' types of D. dipsaci. The aim of this work was to find protein biomarkers that would differentiate oat and lucerne races of D. dipsaci using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOFMS), 2-D PAGE and associated proteomics techniques. Three protein biomarkers at m/z 4313 ± 0.1%, 6300 ± 0.1% and 7460 ± 0.1% were found that discriminate the oat and lucerne races of D. dipsaci using MALDI-TOFMS. The biomarker at m/z 4313 ± 0.1% was the prominent race-specific marker for the lucerne race and is almost absent in the oat race. In addition, proteomic maps were obtained by 2-D PAGE of proteins extracted from oat and lucerne races of D. dipsaci. This analysis allowed a comparison of acetone soluble proteins of oat and lucerne races of D. dipsaci. A prominent protein spot was identified with an isoelectric point (pI) of about 5 and molecular mass ca 4.5 kDa for the lucerne race, which was absent in the oat race. This particular protein was trypsin-digested and analysed by MALDI-TOFMS and MALDI-TOF-TOFMS. The resultant spectra of peptide mass fingerprints (PMF) showed two major peptides at m/z 845 ± 0.1%, 916 ± 0.1% and a less intense peptide at m/z 1258 ± 0.1%. De novo sequencing and MS/MS interpreted amino acid sequences are presented.

Full textAbstract:
In 1990, infection with bean yellow mosaic virus (BYMV) was widespread in subterranean clover (Trifolium subterraneum) pastures in the south-west of Western Australia. When 100 leaves were sampled at random per pasture, the virus was detected by ELISA in 23 of 87 pastures and incidences of infection ranged from 1 to 64%. BYMV was present in all seven districts surveyed, but highest incidences of infection occurred in the Busselton district. In smaller surveys in 1989 and 1992, incidences of infection in pastures were higher than in 1990, and ranged up to 90%. In 1992, when petals from 1703 samples of 59 species of perennial native legumes from 117 sites were tested by ELISA, only 1% were found infected with BYMV. The infected samples came from 5/7 districts surveyed. Species found infected were Kennedia prostrata, K. coccinea, Hovea elliptica and H. pungens. Representative isolates of BYMV from subterranean clover and native legumes did not infect white clover systemically confirming that clover yellow vein virus (CYVV) was not involved. It was concluded that BYMV infection was present in many subterranean clover pastures, but normally at low incidences, except in epidemic years such as 1992. Also, perennial native legumes are unlikely to act as major reservoirs for reinfection of annual pastures each year. In areas of Australia with Mediterranean climates where perennial pastures are absent, persistence of the virus over summer is therefore by some other method than infection of perennials.

Full textAbstract:
Black spot is a major disease of field pea (Pisum sativum L.) production across southern Australia. Known causal agents in Australia include one or more of Mycosphaerella pinodes (Berk. & Bloxam) Vestergr., Phoma medicaginis var. pinodella (L.K. Jones), Ascochyta pisi Lib., or P. koolunga (Davidson, Hartley, Priest, Krysinska-Kaczmarek, Herdina, McKay & Scott) (2), but other pathogens may also be associated with black spot symptoms. Black spot generally occurs on most plants and in most pea fields in Western Australia (W.A.), and during earlier winter/spring surveys of blackspot pathogens, some isolates were tentatively allocated to P. medicaginis var. pinodella despite different cultural characteristics on potato dextrose agar (PDA). Recently, single-spore isolations of a single culture each from an infested pea crop at Medina, Moora, and Mt. Barker in W.A. were made onto PDA. A PCR-based assay with TW81 and AB28 primers was used to amplify from the ITS-5.8S rDNA region. Purified DNA products were sequenced for the three isolates and then BLASTn was used to compare sequences with those in GenBank. Our sequences (GenBank Accession Nos. JN37743, JN377439, and JN377438) had 100% nucleotide identity with P. exigua Desm. var. exigua accessions (GI13385450, GI169894028, and GI189163921), an earlier synonym of what is now known as Boeremia exigua var. exigua ([Desm.] Aveskamp, Gruyter & Verkley) (1). Davidson et al. (2) used the same primers to identify P. koolunga, but none of our isolates were P. koolunga. A suspension of 107 conidia ml–1 of each representative isolate was inoculated onto foliage of 15-day-old field pea cv. Dundale plants and maintained at >90% relative humidity for 72 h postinoculation. Control plants inoculated with just water remained symptomless. Brown lesions were evident by 8 to 10 days postinoculation and mostly 1 to 3 mm in diameter. B. exigua var. exigua was readily reisolated from infected leaves. Isolates have been lodged in the W.A. Culture Collection Herbarium maintained at the Department of Agriculture and Food W.A. (Accession Nos. WAC13500, WAC13502, and WAC13501 from Medina, Moora, and Mt. Barker, respectively). Outside Australia, its synonym P. exigua var. exigua is a known pathogen of field pea (4), other legumes including common bean (Phaseolus vulgaris L.) (4) and soybean (Glycine max [L.] Merr.) (3), and is known to produce phytotoxic cytochalasins. In eastern Australia, P. exigua var. exigua has been reported on common bean (1930s and 1950s), phasey bean (Macroptilium lathyroides [L.] Urb.) and siratro (M. atropurpureum (DC.) Urb.) (1950s and 1960s), mung bean (Vigna radiata [L.] Wilczek.) (1960s), ramie (Boehmeria nivea [L.] Gaudich.) (1939), potato (Solanum tuberosum L.) (1980s), and pyrethrum (Tanacetum cinerariifolium [Trevir.] Schultz Bip.) (2004 and 2007) (Australian Plant Pest Database). To our knowledge, this the first report of B. exigua var. exigua on field pea in Australia, and because of its potential to be a significant pathogen on field pea, warrants further evaluation.

Full textAbstract:
Crop wild relatives – the wild cousins of cultivated plants – are increasingly recognised for their potential to contribute to the productivity, nutritional quality and sustainability of agricultural crops. However, the use of these genetic resources is dependent upon their conservation in genebanks and consequent availability to plant breeders, the status of which has not been comprehensively analysed in Australia. Such conservation assessments are given urgency by reports of increasing threats to natural populations due to habitat destruction, climate change, and invasive species, among other causes. Here we document Australian wild plants related to important food crops, and outline their priorities for ex situ conservation. Given that no major domesticated food plants originated in the country, Australia’s native flora of crop wild relatives is surprisingly rich, including potentially valuable cousins of banana, eggplant, melon, mung bean, pigeonpea, rice, sorghum, sweetpotato, soybean and yam. Species richness of the wild relatives of major food crops is concentrated in the northern and north-eastern tropical regions, in the Northern Territory, Western Australia, and Queensland. Geographic priorities for collecting of these taxa for ex situ conservation, due to the limited representation of their populations in genebanks, largely align with areas of high species richness. Proposed dam building and agricultural expansion in northern Australia make conservation action for these species more urgent. We outline key steps needed for enhancing the ex situ conservation of Australia’s heritage of major food crop wild relatives, and discuss the critical activities required to increase their use.

Full textAbstract:
In tests on seed samples from 26 commercial seed stocks of lucerne (Medicago sativa) to be sown in south-western Australia in 2001, infection with Alfalfa mosaic virus (AMV) was found in 21 and Cucumber mosaic virus (CMV) in 3 of them. Bean yellow mosaic virus (BYMV) and Pea seed-borne mosaic virus (PSbMV) were not detected in any. Incidences of infection within individual affected seed samples were 0.1–4% (AMV) and 0.1–0.3% (CMV), and the infected seed stocks were from 3 (CMV) and at least 11 (AMV) different lucerne cultivars. In a survey of 31 three-year-old lucerne pastures in the same region in 2001, in randomly collected samples, AMV was found in 30 and luteovirus infection in 11 pastures. Pastures in high, medium, and low rainfall zones were all infected. Incidences of AMV within individual infected pastures were high, with 50–98% of plants infected in 20 of them and only 3 having <10% infection, but luteovirus incidences were only 1–5%. In addition to various cultivar mixtures, at least 8 (AMV) and 3 (luteoviruses) different individual lucerne cultivars were infected. When the species of luteovirus present were identified, they were Bean leaf roll virus, Beet western yellows virus ( = Turnip yellows virus), or Subterranean clover red leaf virus ( = Soybean dwarf virus). CMV and legume-infecting potyviruses (BYMV, PSbMV, and Clover yellow vein virus) were not detected in any of the lucerne samples. Acyrthosiphon kondoi infestation was common in the samples collected, and A. pisum and Aphis craccivora were also found. Widespread infection in lucerne stands, and their frequent colonisation by aphid vectors, are cause for concern not only because of virus-induced production losses in lucerne itself but also because they provide virus infection reservoirs for spread to nearby grain legume crops and annual legume pastures.

Full textAbstract:
Subterranean clover (Trifolium subterraneum L.) is the most widely sown pasture legume in southern Australia and resistance to important diseases and pests has been a major plant-breeding objective. Kabatiella caulivora, the cause of clover scorch, is the most important foliar fungal pathogen, and several cultivars have been developed with resistance to both known races. Screening of advanced breeding lines has been conducted to prevent release of cultivars with high susceptibility to other important fungal foliar disease pathogens, including rust (Uromyces trifolii-repentis), powdery mildew (Oidium sp.), cercospora (Cercospora zebrina) and common leaf spot (Pseudopeziza trifolii). Several oomycete and fungal species cause root rots of subterranean clover, including Phytophthora clandestina, Pythium irregulare, Aphanomyces trifolii, Fusarium avenaceum and Rhizoctonia solani. Most breeding efforts have been devoted to resistance to P. clandestina, but the existence of different races has confounded selection. The most economically important virus diseases in subterranean clover pastures are Subterranean clover mottle virus and Bean yellow mosaic virus, while Subterranean clover stunt virus, Subterranean clover red leaf virus (local synonym for Soybean dwarf virus), Cucumber mosaic virus, Alfalfa mosaic virus, Clover yellow vein virus, Beet western yellows virus and Bean leaf roll virus also cause losses. Genotypic differences for resistance have been found to several of these fungal, oomycete and viral pathogens, highlighting the potential to develop cultivars with improved resistance. The most important pests of subterranean clover are redlegged earth mite (RLEM) (Halotydeus destructor), blue oat mite (Penthaleus major), blue-green aphid (Acyrthosiphon kondoi) and lucerne flea (Sminthurus viridis). New cultivars have been bred with increased RLEM cotyledon resistance, but limited selection has been conducted for resistance to other pests. Screening for disease and pest resistance has largely ceased, but recent molecular biology advances in subterranean clover provide a new platform for development of future cultivars with multiple resistances to important diseases and pests. However, this can only be realised if skills in pasture plant pathology, entomology, pre-breeding and plant breeding are maintained and adequately resourced. In particular, supporting phenotypic disease and pest resistance studies and understanding their significance is critical to enable molecular technology investments achieve practical outcomes and deliver subterranean clover cultivars with sufficient pathogen and pest resistance to ensure productive pastures across southern Australia.

Full textAbstract:
Vigna marina (Burm.) Merr., the dune bean or notched cowpea, is a tropical creeping vine that grows on sand dunes along the coastal regions of Taiwan. Although V. marina is a weed, some varieties are also grown for fodder and food. This legume is a natural host of Bean common mosaic virus in the Solomon Islands (1) and Alfalfa mosaic virus or Beet western yellows virus in Australia (2). In April 2009, plants of V. marina showing severe mosaic and chlorotic ringspots on the foliage were found in the coastal region of Hualien County in eastern Taiwan. Indirect ELISA on a single diseased plant showed positive results with antibodies against the cucumber isolate of Cucumber mosaic virus (CMV) but negative to Broad bean wilt virus-1, Broad bean wilt virus-2, and some potyviruses (Agdia Inc., Elkhart, IN). A pure isolate of CMV was obtained from V. marina through three successive passages of single lesion isolation in sap-inoculated Chenopodium quinoa. Results of mechanical inoculations showed that the CMV-V. marina isolate was successfully transmitted to C. amaranticolor, C. murale, C. quinoa, Chrysanthemum coronarium, Gomphrena globosa, Nicotiana benthamiana, N. tabacum cv. Vam-Hicks, Phaseolus limensis, P. lunatus, P. vulgaris, Tetragonia tetragonioides, V. marina, V. radiata, and V. unguiculata subsp. sesquipedalis. These results of artificial inoculations were confirmed by ELISA. Homologous reactions of the CMV-V. marina isolate with a stock polyclonal antiserum against the CMV-cucumber isolate (4) were observed in sodium dodecyl sulfate-immunodiffusion. To determine the specific CMV subgroup, total RNA was extracted from inoculated leaves of C. quinoa using the Total Plant RNA Extraction Miniprep System (Viogene, Sunnyvale, CA). A DNA fragment of 940 bp covering the 3′ end of the coat protein gene and C-terminal noncoding region of RNA-3 was amplified using the Cucumovirus-specific primers (3) after reverse transcription (RT)-PCR with AccuPower RT/PCR PreMix Kit (Bioneer, Daejeon, Korea). The product was gel purified by Micro-Elute DNA/Clean Extraction Kit (GeneMark Technology Co., Tainan, Taiwan) and cloned in yT&A Cloning Vector System (Yeastern Biotech Co., Taipei, Taiwan) for sequencing (Mission Biotech Co., Taipei, Taiwan) and the sequence was submitted to GenBank (No. HM015286). Pairwise comparisons of the sequence of CMV-V. marina isolate with corresponding sequences of other CMV isolates revealed the maximum (95 to 96%) nucleotide identities with CMV subgroup IB isolates (strains Nt9 and Tfn) compared with 94 to 95% identities with subgroup IA isolates (strains Y and Fny) or 77 to 78% identities with subgroup II (strains LS and Q). These results suggest that CMV is the causal agent for the mosaic disease of V. marina in Taiwan and the isolate belongs to subgroup I. To our knowledge, this is the first report of V. marina as a natural host of CMV. This strain of CMV with specific pathogenicity could threaten crop production in the coastal zones. In addition, V. marina associated with native coastal vegetation was injured by CMV infection, which might lead to ecological impacts on shoreline fading. References: (1) A. A. Brunt.

Full textAbstract:
A new strain of bean yellow mosaic virus (BYMV), a non-necrotic strain, was found in south-west Western Australia. It differs from the original necrotic strain of BYMV in that it does not kill Lupinus angustifolius (narrow-leafed lupin) plants, but causes symptoms of mottle and stunting, or dead growing points, fleshy expanded leaves, and stunting. A survey of L. angustifolius crops during September and October 1997 compared the distribution and incidence of the necrotic strain with that of the non-necrotic strain. Based on 1000 plants inspected at the edge of each crop, the necrotic strain was found in 100 of 102 crops while the non-necrotic strain was found in 64 of them. Incidences ranged from 0.3 to 56% (necrotic strain) and 0.1 to 7% (non-necrotic strain) of plants counted. Both strains were present over the whole range of the survey. Wild L. angustifolius and L. luteus (yellow lupin) populations were also inspected. The necrotic and non-necrotic strains were found in 31 and 9 of the 34 L. angustifolius populations examined, respectively. Incidences ranged from 0.1 to 28% (necrotic strain) and 0.1 to 3% (non-necrotic strain) of plants counted. BYMV was found in 9 of 11 wild L. luteus populations with incidences ranging from 0.3 to 7% of plants counted. In a separate survey in which samples of L. angustifolius crops, with necrotic symptoms suspected of being caused by Colletotrichum gloeosporioides (lupin anthracnose disease), were examined, 37 of 130 samples had typical necrotic BYMV symptoms. Samples with these necrotic symptoms also came from northern and eastern wheatbelt areas not normally associated with BYMV infection. When 8 BYMV isolates cultured by sap inoculation in Trifolium subterraneum (subterranean clover) were tested by aphid transmission to L. angustifolius plants in 1994 and again in 1997, the isolates of the 2 strains behaved the same on both occasions causing only necrotic (3 isolates) or non-necrotic (5 isolates) symptoms. Thus, despite repeated subculture by sap inoculation over a 3.5-year period, the 2 BYMV strains still remained distinct. An isolate collected from wild L. luteus in 1997 produced only non-necrotic symptoms in L. angustifolius. The non-necrotic strain caused symptoms typical of BYMV in hosts other than L. angustifolius, reacted strongly with BYMV antiserum, and failed to react with antiserum to clover yellow vein virus. In a BYMV-infected lupin crop, grain yields of individual L. angustifolius plants infected early with the non-necrotic strain were decreased by 95%. Shoot weights, seed number, and seed size were also greatly decreased. Widespread occurrence of the non-necrotic strain of BYMV is cause for concern for the lupin industry.

"Bean yellow mosaic potyvirus infection of alternative hosts associated with subterranean clover (Trifolium subterraneum and narrow-leafed lupins (Lupinus angustifolius): field screening procedure, relative susceptibility/resistance rankings, seed transmission and persistence between growing seasons." Australian Journal of Agricultural Research 46, no.1 (1995): 135. http://dx.doi.org/10.1071/ar9950135.
Full textAbstract:
A field screening procedure was devised to determine relative susceptibility and resistance rankings for hosts of bean yellow mosaic potyvirus (BYMV) using BYMV-infected Trifolium subterraneum plants transplanted at eack end of single row test plots. Natural spread of BYMV by aphids resulted in BYMV symptoms in test lines. Four test lines were ranked as highly resistant, nine were resistant, seven were moderately resistant, eight were susceptible and two were highly susceptible to BYMV infection. Disease progress curves plotted for each test line assisted in the ranking process. Relative rankings were independent of flowering date and presence of host alkaloids. Acrythosiphon kondoi, Myzus persicae and Rhopalosiphum padi were the predominant aphid species caught in traps associated with field screening plots. Seven plant species tested were new BYMV host records. Seed of four plant species systemically infected following sap inoculation with BYMV was tested, and seed transmission detected in Melilotus indica (0.5%). When seed of 19 alternative host species that became systemically infected through natural spread was tested, seed transmission was found in Medicago polymorpha (0.9%), Medicago truncatula (0.3%), M. indica (1%), T, arvense (0. 1%), T. campestre (0.2%) and T. glomeratum (0.05%). No seed transmission was detected in T. subterraneum. It is concluded that under broadacre agriculture in the Mediterranean climate of Western Australia, seed-borne infection in naturalized M. polymorpha, T. arvense, T. campestre and T. glomeratum growing in T. subterraneum pastures probably provides the principal means by which BYMV persists over the dry summer to act as primary sources for subsequent spread. The species most likely to contribute to BYMV spread within T. subterraneum pastures and from them to Lupinus angustifolius crops were L. cosentinii, T. campestre, T. dubium and T. subterraneum itself.

Full textAbstract:
In the 1980s, an extremely successful Nescafé Gold Blend coffee advertising campaign dared to posit, albeit subliminally, that a love relationship was inextricably linked to coffee. Over several years, an on-again off-again love affair appeared to unfold onscreen; its ups and downs narrated over shared cups of coffee. Although the association between the relationship and Gold Blend was loose at best, no direct link was required (O’Donohoe 62). The campaign’s success was its reprisal of the cultural myth prevalent in the West that coffee and love, coffee and relationships, indeed coffee and intimacy, are companionate items. And, the more stable lover, it would seem, is available on the supermarket shelf. Meeting for coffee, inviting a potential lover in for a late-night cup of coffee, or scheduling a business meeting in an espresso bar are clichés that refer to coffee consumption but have little to do with the actual product. After all, many a tea-drinker will invite friends or acquaintances “for coffee.” This is neatly acknowledged in a short romantic scene in the lauded feature film Good Will Hunting (1997) in which a potential lover’s suggestion of meeting for coffee is responded to smartly by the “genius” protagonist Will, “Maybe we could just get together and eat a bunch of caramels. [...] When you think about it, it’s just as arbitrary as drinking coffee.” It was a date, regardless. Many in the coffee industry will argue that coffee—rather than tea, or caramel—is legendary for its intrinsic capacity to foster and ignite new relationships and ideas. Coffee houses are repeatedly cited as the heady location for the beginnings of institutions from major insurance business Lloyd’s of London to the Boston Tea Party, J.K. Rowling’s Harry Potter series of novels, and even Western Australian indie band Eskimo Joe. This narrative images the coffee house and café as a setting that supports ingenuity, success, and passion. It is tempting to suggest that something intrinsic in coffee renders it a Western social lubricant, economic powerhouse, and, perhaps, spiritual prosthesis. This paper will, however, argue that the social and cultural production of “coffee” cannot be dissociated from feeling. Feelings of care, love, inspiration, and desire constellate around “coffee” in a discourse of warm, fuzzy affect. I suggest that this blooming of affect is not superfluous but, instead, central to the way in which coffee is produced, represented and consumed in Western mass culture. By exploring the currently fashionable practice of “direct trade” between roasters and coffee growers as represented on the Websites of select Western roasting companies, the repetition of this discourse is abundantly clear. Here, the good feelings associated with cross-cultural friendship are figured as the condition and reward for the production of high quality coffee beans. Money, it seems, does not buy happiness—but good quality coffee can. Good (Colonial) Feelings Before exploring the discursive representation of friendship and good feeling among the global coffee community with regard to direct trade, it is important to account for the importance of feeling as a narrative strategy with political affects and effects. In her discussion of “happy objects,” cultural theorist of emotion Sara Ahmed argues that specific objects are associated with feelings of happiness. She gives the telling example of coffee as an object intimately tied with happy feeling within the family. So you make coffee for the family, and you know “just“ how much sugar to put in this cup and that. Failure to know this “just“ is often felt as a failure of care. Even if we do not experience the same objects as being pleasurable, sharing the family means sharing happy objects, both in the sense of sharing knowledge (of what makes others happy) and also in the sense of distributing the objects in the right way (Ahmed, Promise 47). This idea is derived from Ahmed’s careful consideration of affective economies. She suggests emotions neither belong to, or are manufactured by, discrete individuals. Rather, emotions are formed through social exchange. Relieved of imagining the individual as the author of affect, we can consider the ways in which affect circulates as a product in a broad, vitalising economy of feeling (Ahmed, Affective 121). In the example above, feelings of care and intimacy attached to coffee-making produce the happy family, or more precisely, the fleeting instant of the family-as-happy. The condition of this good feeling is not attributable to the coffee as product nor the family as fundamentally happy but rather the rippling of happy feeling through sharing of the object deemed happy. A little too much sugar and happiness is thwarted, affect wanes; the coffee is now bad(-feeling). If we return briefly to the Nescafé Gold Blend campaign and, indeed, Good Will Hunting, we can postulate following Ahmed that the coffee functions as a love object. Proximity to coffee is identified by its apparent causation of love-effects. In this sense, “doing coffee” means making a fleeting cultural space for feeling love, or feeling good. But what happens when we turn from the good feeling of consumption to the complex question of coffee production and trade? How might good feeling attach to the process of procuring coffee beans? In this case, the way in which good feeling seems to “stick to” coffee in mass culture needs to be augmented with consideration of its status as a global commodity traded across sociopolitical, economic, cultural and national borders. Links between coffee and colonialism are long established. From the Dutch East India Company to the feverish enthusiasm to purchase mass plantations by multinational corporations, coffee, colonialism and practices of slavery and indentured labour are intertwined (Lyons 18-19). As a globally traded commodity across a range of political regimes and national borders, tracing the postcolonial and neocolonial relations between multinational companies, small upscale boutique roasters, plantation owners, coffee bean co-ops, regulatory bodies, and workers is complex at best. In what may appear a tangential approach, it is nonetheless instructive to consider that colonial relations are constituted through affective components that support and fuel economic and political exchange (Stoler, Haunted). Again, Ahmed offers a useful context for the relationship between the imperative toward happiness and colonial representation. The civilizing mission can be redescribed as a happiness mission. For happiness to become a mission, the colonized other must be first deemed unhappy. The imperial archive can be described as an archive of unhappiness. Colonial knowledges constitute the other as not only an object of knowledge, a truth to be discovered, but as being unhappy, as lacking the qualities or attributes required for a happier state of existence (Ahmed, Promise 125). The colonising aspect of the relations Ahmed describes includes the “mission” to construct Others as unhappy. Understood as happiness detractors, colonial Others become objects that threaten the radiant appeal of happiness as part of an imperial moral economy. Hence, it is the happiness of the colonisers that is secured through the disavowal of the feelings of Others. Moreover, by documenting colonial unhappiness, colonising forces justify the sanctity of happiness-making through violence. As Ann Stoler affirms, “Colonial states had a strong interest in affective knowledge and a sophisticated understanding of affective politics” (Carnal 142). Colonising discourses, then, are inextricably linked to regimes of sense and feeling. Stoler also writes that European-ness was established through cultivation of an inner sense of self-worth associated with ethics, individuality and autonomy (Haunted 157). The development of a sense of belonging to Europe was hence executed through feeling good in both moral and affective senses of the word. Although Stoler argues her case in terms of the affective politics of colonial sexualities and desire, her work is highly instructive for its argument that emotion is crucial to structures of power in colonial regimes. Bringing Stoler’s work into closer proximity with Ahmed’s postulation of State happiness and its objects, I am now going to suggest that coffee is a palimpsestic cultural site at which to explore the ways in which the politics of good feeling obscure discomforting and complex questions of power, exploitation, and disadvantage in global economies of coffee production and consumption. Direct Trade In the so-called “third wave” specialty coffee market that is enjoying robust growth in Australia, America, and Europe, “direct trade” across the globe between roasters and plantation owners is consistently represented as friendly and intimate despite vast distances and cultural difference. The “third wave” is a descriptor that, as John Manzo describes in his sociological exploration of coffee connoisseurship in privileged Western online and urban fora, refers to coffee enthusiasts interested in brewing devices beyond high-end espresso machines such as the cold drip, siphon, or pour-over. Jillian Adams writes further that third wavers: Appreciate the flavour nuances of single estate coffee; that is coffee that is sourced from single estates, farms, or villages in coffee growing regions. When processed carefully, it will have a distinctive flavour and taste profile that reflects the region and the culture of the coffee production (2). This focus on single estate or “single origin” coffee refers to beans procured from sections of estates and plantations called micro-lots, which are harvested and processed in a controlled manner.The third wave trend toward single origin coffees coincides with the advent of direct trade. Direct trade refers to the growing practice of bypassing “middlemen” to source coffee beans from plantations without appeal to or restriction by regulatory bodies. Rather, as I will show below, relationships and partnerships between growers and importers are imagined as sites of goodwill and good feeling. This focus on interpersonal relationships and friendships cannot be disarticulated from the broader cross-cultural context at stake. The relationships associated with direct trade invariably take place across borders that are also marked by economic, cultural and political differences in which privileged Western buyers engage with non-Western growers on low incomes. Drawing from Ahmed’s concern that the politics of good feeling is tied to colonial nostalgia, it is compelling to suggest that direct trade is haunted by discourses of colonisation. At this point of intersection, I suggest that Western mass cultural associations of coffee with ease, intimacy and pure intentions invite consumers to join a neocolonial saga through partaking in imagined communities of global coffee friends. Particularly popular in Australia and America, direct trade is espoused by key third wave coffee roasters in Melbourne, Portland and Seattle. Melbourne Coffee Merchants are perhaps the most well-known importers of directly traded green bean in Australia. On their Web page they describe the importance of sharing good feelings about high quality coffee: “We aim to share, educate, and inspire, and get people as excited about quality coffee as we are.” A further page describing the Merchants’s mission explains, “Growers are treated as partners in the mission to get the worlds [sic] finest beans into the hands of discerning customers.” The quality of excitement that circulates through the procuring of green beans is related to the deemed partnership between Merchants and the growers. That is, it is not the fact of the apparent partnership or its banality that is important, but the treating of growers as partners that signifies Merchants’s mission to generate good feeling. This is a slight but crucial distinction. Treating the growers as partners participates in an affective economy of excitement and inspiration—how the growers feel is, presumably, in want of such partnership.Not dissimilarly, Five Senses Coffee, boutique roasters in Melbourne and Perth, offer an emotional bonus with the purchase of directly traded coffees. “So go on, select one of our Direct Trade products and bask in the warm glow you get knowing that the farmer who grew the beans that you’re enjoying is reaping the rewards too!” The rewards that the growers are deemed to be receiving are briefly explained in blog posts on the Five Senses news Web page. I am not suggesting that these friendships and projects are not legitimate. Rather, the willingness of Five Senses to negotiate rates with growers and provide the community with an English teacher, for example, fuels an economy of Westerners’s good feelings and implies conventional trading produces unhappiness. This obscures grounds for concern that the provision of an English teacher might indeed serve the interests of colonising discourses. Perhaps a useful entry point into this narrative form is founded in the recently self-published book Coffee Trails by Toby Smith, founder of boutique Australian roaster Toby’s Estate. The book is described on the Toby’s Estate Web page as follows:Filled with personal anecdotes and illustrating his relationships developed over years of visiting the farmers to source his coffee beans, Smith’s commentary of his travels, including a brush with Jamaican customs officials and a trip to a notoriously dangerous Ethiopian market, paints an authentic picture of the colourful countries that produce the second most traded product in the world. [...] Coffee Trails has been Smith’s labour of love over the past two years and the end product is a wonderfully personal account of a man fulfilling his lifelong dream and following his passion across the world. Again, the language of “passion” and “love” registers direct trade coffee as a happy object. Furthermore, despite the fact that coffee is also grown in Australia, the countries that are most vivid in the epic imagination are those associated with “exotic” locations such as Ethiopia and Jamaica. This is arguably registered through the sense that these locations were where Smith encountered danger. Having embarked on a version of the quintessential hero’s journey, Smith can be seen as devoted to, and inspired by, his love-object. His brushes with uncivilised authorities and locations carry the undertones of a colonial imaginary, in which it can be argued Smith’s Western-ness is established and secured as goodwill-invoking. After all, he locates and develops relationships with farmers and buys their coffee which, following the logic of happy objects, disperses and shares good feelings.Gloria Jean’s Coffees, which occupies a similar market position in Australia to the multinational “specialty” coffee company Starbucks (Lyons), also participates in the dispersal of coffee as a happy object despite its mass scale of production and lack of direct trade capability (not unexpectedly, Starbucks hosts a Relationships campaign aimed at supporting humanitarian initiatives and communities). Gloria Jean’s campaign With Heart allocates resources to humanitarian activities in local Australian communities and worldwide in coffee-growing regions. Their Web page states: “With Heart is woven throughout Gloria Jeans Coffee houses and operations by the active participation of Franchise Partners, support office and team members and championed across Australia, by our With Heart Ambassadors.“ The associative message is clear: Gloria Jean’s Coffees is a company indissociable from “heart,” or perhaps loving care, for community.By purchasing coffee, Gloria Jean’s customers can be seen to be supporting heartening community projects, and are perhaps unwittingly working as ambassadors for the affective economy in which proximity to the happy object—the heart-centred coffee company—indicates the procurement of happiness for someone, somewhere. The sale of good feeling enables specialty coffee companies such as Gloria Jean’s to bypass market opportunities associated with Fair Trade regulatory provisions, which, as Carl Obermiller et al. find in their study of Fair Trade buying patterns, also profit from consumers’ purchase of good feeling associated with ethically-produced objects. Instead, assuring consumers of its heart-centredness, Gloria Jean’s Coffees is represented as an embodiment not of fairness but kindness, and perhaps love, for others. The iconography and history of direct trade coffee is most closely linked to Intelligentsia Coffee of Chicago in the USA. Intelligentsia describes its third wave roasting and training business as the first to engage in direct trade in 2003. Its Web page includes an image of an airplane to which the following pop-up is linked: “Our focus is not just identifying quality coffee, but developing and rewarding it. To do this means preserving and developing strong relationships despite the considerable distance. At any given time, there is at least one Intelligentsia buyer at origin.” This text raises the question of what constitutes quality coffee. It would appear that “quality coffee” is knowledge that Intelligentsia owns, and which is rewarded financially when replicated to the satisfaction of Intelligentsia. The strength of the relationships in this interaction is closely linked to the meeting of clear conditions and expectations. Indeed, we are reassured that “at any time” an Intelligentsia buyer is applying these conditions to the product. Quality, then, is at least in part achieved by Intelligentsia through its commitment to travelling long distances to oversee the activities and practices of growers. This paternalistic structure is figured in terms of “strong relationships” rather than, perhaps, a rigorous and shrewd business model (which is assumedly the province of mass-market Others).Amid numerous examples found in even a cursory search on the Web, the overwhelming message of direct trade is of good feeling through care. Long term relationships, imagined as virtuous despite the opacity of the negotiation procedure in most cases, narrates the conviction that relationship in and of itself is a good in what might be called the colonial redramatisation staked by an affective coffee economy. Conclusion: Mourning CoffeeIn a paper on happiness, it might appear out of place to reference grief. Yet Jacques Derrida’s explication of friendship in his rousing collection The Work of Mourning is instructive. He writes that death is accommodated and acknowledged “in the undeniable anticipation of mourning that constitutes friendship” (159). Derrida maintains close attention to the productivity and intensity of Otherness in mourning. Thus, friendship is structurally dependent on impending loss, and it follows that there can be no loss without recognising the Otherness of the other, as it were. Given indifference to difference and, hence, loss, it is possible to interpret the friendships affirmed within direct trade practices as supported by a kind of mania. The exuberant dispersal of good feeling through directly traded coffee is narrated by emotional journeys to the primordial beginnings of the happy-making object. That is, fixation upon the object’s brief survival in “primitive” circumstances before its perfect demise in the cup of discerning Western clientele suggests a process of purification through colonising Western knowledges and care. If I may risk a misappropriation of Sara Ahmed’s words; so you make the trip to origin, and you know “just” what to pay for this bean and that. Failure to know this “just” is often felt as a failure of care.
