We have an unpredictable climate so timing the move from pasture to crop is a risk; lucerne is difficult to establish and remove; and the need to manage the water table never stops... "Simplistically, if we look at a six-year phase farming rotation with three years under crop and three years under lucerne, we"re at best achieving 50 percent of potential crop yield over that time," he says... "We"ve found that lucerne"s ability to control recharge is much better from the second year of establishment, so perhaps we have to look at crop being over-sown in the second year," he says...

The project has shown that the use of variety management packages for new pulse varieties has the potential to increase pulse production and reliability of production... Adoption of recommendations developed in this project will optimise grain yield benefits of new varieties, resulting in higher potential returns, and minimised production risks, preventing major economic losses that can occur with total crop failure... The aim of the project was to collect data for and develop simple regional variety specific agronomic management packages (VSAP) for new lentil, field pea and chickpea varieties...

Optimum canola densities tested for lower-rainfall zones.. Mark Seymour, leader of the GRDC-DAFWA tactical break crop agronomy project in WA, at a trial site examining canola plant density at Salmon Gums in 2013... Mr Seymour says, overall, the trials highlighted that economic optimum plant density for canola differs for each variety and herbicide-tolerance system and adjustments need to be made according to the rainfall zone...

Northern chickpea growers are advised to sow at optimal seeding rates, irrespective of sowing date, to ensure early canopy closure and minimise the risk of viruses... Dr Andrew Verrell, NSW Department of Primary Industries (NSW DPI) research agronomist says recent research supported by the Grains Research and Development Corporation (GRDC) shows growers should sow chickpeas at optimal seeding rates - irrespective of sowing date... Dr Verrell says there are more than 14 species of virus that naturally infect chickpeas and are spread by airborne insects, particularly aphids...

Western Australian research investigating whether it is economic to reseed a canola crop that has established poorly suggests that in many cases it might not be worthwhile... As part of the 'Tactical break crop agronomy project', funded by the Grains Research and Development Corporation (GRDC), Mr Seymour conducted trials last year aimed at determining the point at which reseeding a low density canola crop was worthwhile... The trials assessed sowing canola before or at the break of the season at plant densities of five, 10, 15 and 30 plants per square metre, compared with plots resown at 30 plants/m over the top of five and 10 plants/m and plots sown normally (not resown) at later dates at five to 60 plants/m ...
