Ground Cover Supplement : GC Supplement - Pulse breeding
PULSE BREEDING GROUND COVER AGRONOMY 13 OZP0602 is high yielding and suitable for low and medium-rainfall areas where it may not need to be sown as early as KaspaA to maximise yields. This makes OZP0602 a safer option where sowing needs to be delayed due to disease, frost, weeds or excessive growth issues. n Optimising management in dry seasons NSW research shows that under stressed conditions, grain production is inevitably maximised when biomass is maximised. This results from a combination of adopting early flowering and quick-maturing varieties; sowing early (1 to 15 May); using narrow row spacing (less than or equal to 30cm); and targeting plant densities of 40 or more plants per square metre. However, these management options do not apply when seasonal conditions are more favourable, as was more often the case throughout the 1990s. Results from the Southern Pulse Agronomy Project's trials on early sowing and row spacing were reported in the Ground Cover agronomy supplement (July--August 2009). □ Show and tell A series of specialist pulse field days provided a unique opportunity for all sectors of the industry to meet and share THERE IS NO substitute for seeing how new varieties perform in the paddock and talking to experts face to face. A series of pulse field days run by members of the Southern Pulse Agronomy Project and Pulse Australia gave growers the opportunity to do both. Grain growers attending the events held in South Australia, Victoria and New South Wales were able to talk to the Pulse Breeding Australia breeders and agronomists, pathologists and marketers about current and new varieties, and to international pulse breeders from Canada and Syria. At these events the new chickpea variety PBA SlasherA and the two new lentils PBA FlashA and PBA BountyA were launched. "These new varieties are better adapted to pulse- growing regions, and with improved yield and quality they should improve production stability for both growers and marketers, which in turn should provide confidence to grow the market," said South Australian Research and Development Institute (SARDI) research agronomist and PBA breeding collaborator Larn McMurray. For major pulse crops, breeding and agronomy research is carried out concurrently and at each event the latest agronomy research was displayed and discussed. For example, at the event at Yenda, western NSW, the agronomy focus was on pulse management for tough seasonal conditions when there is minimal subsoil moisture at sowing. Eric Armstrong and colleagues from the NSW Department of Industry and Investment (DII) demonstrated how matching crop type to available soil moisture at sowing influenced production. Chickpeas and field peas have been found to be the two pulses most adapted to this region, but chickpea production is more stable with good subsoil moisture at seeding. If subsoil moisture at sowing is limited field peas are the better performer. "Ultimately we need to maximise biomass to maximise production; our trials show that sowing early flowering, fast maturing varieties, in the first two weeks of May, at 30cm row spacing to achieve plant populations of at least 40 plants/m2, produces the best yield in these tough conditions," Eric Armstrong says. In Victoria, presentations included information on inter-row sowing into standing stubble at different row spacings, and on the herbicide tolerance and weed control research. Time of sowing and inoculation of pulses were two of the agronomy topics presented in SA. Representatives from pulse seed commercialisation companies, processors, marketers and exporters provided information to help growers maximise pulse value. A pulse pathologist and researchers involved with the National Rhizobium Program were also participants in most events. "Having an event focused on pulses enables all members of the value chain to contribute, which makes these events exciting, informative and valuable to all participants," says Jason Brand of the Victorian Department of Primary Industries. "More than 400 growers and agronomists attended these events, which illustrates the current high level of interest in pulses." □ GRDC Research Code DAV00084 More information: Dr Jason Brand, research agronomist -- pulses, Victorian DPI, 03 5362 2341, email@example.com; Larn McMurray, research scientist, SARDI, 08 8842 6265, firstname.lastname@example.org; Eric Armstrong, research agronomist (pulses), NSW DII, 02 6938 1814, email@example.com LATEST AGRONOMY RESEARCH WAS DISPLAYED AND DISCUSSED.
