Wheat yield increases of 1.19t/ha possible in the north.. Maps detailing actual and achievable yield data have been compiled by the CSIRO and will be made accessible through a Grains Research and Development Corporation (GRDC) funded project... Dr Hochman said the research found that the northern region's yields were 5.3% lower than relative yields in the southern region and 8.9% lower than in the western region, suggesting there is significant scope to boost yields in the north through better application of current technologies and best practice...

Figure 1: Feed grain demand estimate superimposed on predicted seasonal variability in supply.. Demand was calculated from feed grain usage based on animal numbers (feedlot cattle, pigs, poultry, dairy) as about 3.65Mt per annum... Risk was calculated as the percentage of years that did not exceed a threshold (near breakeven) yield, which was set at 1.5 t/ha...

" Agribusiness Crop Updates 2006 Analysis of a wheat-pasture rotation in the 330 annual rainfall zone using the STEP model Andrew Blake and Caroline Peek, Department of Agriculture, Geraldton mm.. KEYMESSAGES Self regenerating biserrula pastures grown in rotation with wheat were more profitable than volunteer pastures based on the assumption that the legume phase can lift wheat yields and improve grain quality... It was assumed that wheat grown in the first or second year after legume pasture would be higher in protein and attract the $10/tonne premium paid in the AH segregation...

Figure 1: Map of estimated average yield developed from the PYM approach.. A new tool allowing a low-cost rapid assessment of whole-farm yield variability - pseudo yield mapping - may help farmers justify investment in precision agriculture technology... Researchers from the Victorian DPI, Dr Peter Fisher and Dr Mohammad Abuzar, are using historical satellite images as a method of estimating the level of variability across paddocks or properties before growers need to invest in capital equipment...

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)...

It is important to remember that there are many ways in which PA can be adopted and used to make or save money, improve timeliness or environmental management and to carry out onfarm trials... If a grower purchases a GPS unit using one system and then changes to one using the other system, locations will not be translate accurately... Growers are not confident in using the currently available indices in making cropping decisions...

4. Desiccate late season weeds Desiccating the crop too early can result in greater lodging particularly if harvest is then delayed, and may impact on both grain yield and quality... Sorghum growers and advisers in Qld have appeared more comfortable with optimal timing of sorghum spray-out, largely based on grain black layer (abscission zone) development... There was no impact on yield or grain quality from any timing...

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 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...

Australian grain growers respond to the pressure of rising cost of production by adopting and adapting new technologies to narrow the gap between their actual yields (Ya) and their water limited yield potential (Yw)... The project will use annual maps of Ya, Yw and Yg to develop an interactive tool that will enable farmers and their advisers to assess the yield gap of their fields relative to Yw and Ya in their statistical local area (SLA)... The decision to aim for a higher yield is a trade-off between profit and risk...

Maps detailing actual and achievable yield data have been compiled by the CSIRO and will be made accessible through a Grains Research and Development Corporation (GRDC) funded project... The study suggests that farmers in the northern region could achieve average yields of 2.9 t/ha," Dr Hochman said... Dr Hochman said the research found that the northern region's yields were 5.3% lower than relative yields in the southern region and 8.9% lower than in the western region, suggesting there is significant scope to boost yields in the north through better application of current technologies and best practice...
