A research project in the Great Southern region has demonstrated that the decision tool Yield Prophet could help local growers maximise crop yields and minimise risks associated with management decisions... "Following a number of extremely variable seasons, many growers in the region have lacked the confidence to implement management practices to maximise yields, and have been taking an approach of 'less risk' for their in-season decision making," Mr Whisson said... Mr Whisson said the benefit of Yield Prophet to local growers over the course of the season was obvious, especially when it came to making nitrogen and fungicide decisions based on forecast yield, as well as providing side benefits such as yield estimates for insurance purposes...

Although a high-risk crop, oaten hay has the potential to outperform all other cereals with respect to gross margins... The widespread use of genetic analysis in agriculture is limited by economic factors... In the short term, fungicides used at seeding (seed dressings or applied in-furrow with fertiliser) and foliar fungicide sprays will mitigate risk and minimise losses...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

Queensland University of Technology's Professor Peter Grace discusses strategies to help avoid nitrogen losses at a recent GRDC Grains Research Update... The loss is caused by chemical reactions on the surface of the soil, and only occurs in alkaline soils when ammonium-based fertiliser is broadcast and there is no rain to wash it into the soil... Rain is required to wash the fertiliser deeper into the soil profile, but not too much that it could cause denitrification or leaching...

Figure 1 Growth of wheat plants treated with Hoag land nutrient solutions of varying salinity.. Experiments in our project have shown that transient salinity - accumulation of salt in root zone layers not influenced by the watertable - affects crop yield and growth in dryland regions, mainly by reducing water-use efficiency of crops through osmotic effect... Hoagland solution was used to reduce the specific ion toxicity to a minimal level and find out the effects of osmotic pressure, irrespective of the type of salt...

Bentleg opener brings speed and control to no-till.. A University of South Australia (UniSA) engineering project is a step closer to delivering a new furrow opener design that reduces soil disturbance and increases operating speeds in no-till seeding... "We need to investigate this interaction between opener design and speed to maintain low soil disturbance, to see why some designs perform better at high speed," he says...

Although biochar addition to soil did decrease inorganic N leaching, soil N mineralisation either decreased or did not change... The application of pyrolysed organic matter or biochar to soil can remediate decreased SOM and sequester C. The application of biochar to soil has also been shown to improve soil fertility and enhance yields of crops such as maize, wheat and peanuts... As biochar addition to soil can increase microbial community size and activity, previous research has hypothesised that this mechanism may be responsible for enhanced N mineralisation rates and contributes to the demonstrated improvements of N fertiliser use efficiency (up to 90%) in glasshouse-based agronomic research...
