" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Prices dictate profitable nutrition.. A simple framework has been developed to help growers and advisers make better fertiliser decisions based on maximising profits, rather than crop yields... Her analyses of N and wheat prices during the past decade indicate gross margins are optimised when growers and advisers can predict the yield response to a wide range of nutrient rates, rather than those typically used for the expected yield...

We in the north are still working out where and how best to use P in our fertiliser programs... The representation for different crop species, soil types and seasons is somewhat limited... GRDC Grains Research Update Goondiwindi, March 2014 Figure 3...

When choosing varieties, consider long term yield and protein results for your region, disease resistance/tolerance packages and target grades... In 2013 variety choice played a significant role in final grain yield and grain protein concentration, which influenced the capacity to achieve APH... Across-site analysis was conducted to determine the contribution of trial factors (trial site, nitrogen rate and variety) to grain yield, grain protein concentration and grain nitrogen yield across the 2013 trials (Table 1)...

GRDC Grains Research Update Coonabarabran, February 2014 most sites achieved those returns within 2 crop seasons after deep P application may at least partly reflect the string of wetter seasonal conditions in recent years, although the results from Jandowae, Capella and Gindie all included dry seasons in at least one of the crops followed... Overall, the performance of the barley grain only varieties showed they are capable of producing around 6 t/ha of dry matter and still yielding between 2.7 and 3.4 t/ha of grain... Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)...
