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...

Previous cereal research work in northern NSW has focussed on in-crop nitrogen application as a "top-up" treatment with the greater proportion of N being applied to the seedbed... Work in 2006 and 2007 showed significant differences in canopy structure when nitrogen was delayed until stem elongation (GS31) but in both years that was no significant increase in grain yield compared to when N was applied at sowing... Figure 3: Influence of split N applications on grain yield from early and main sown EGA Gregory For the later sowing, results are very similar to those in 2006 and 2007 with split applied or N applied at GS31 maintaining grain yields but limited significant yield response compared to the seedbed N treatment (figure 3)...

Efficiency sits at the top of farm evolution.. Following dramatic changes to his family's practices since his grandfather began farming their property in the Toobeah district in 1936, Robert says their mixed-farming approach is now dominated by the pursuit of increased efficiency... "There are rising input costs, but there are also efficiency increases," Robert says...

Early or preventative foliar sprays, applied from GS32 onwards on moderately susceptible varieties, have provided the best returns in northern trials over the last three years High grain prices and low fungicide costs mean breakeven yield benefits required are often only 1-2% Application can be the major cost of treatment Consider timing when stripe rust in area but not in crop or in tank mixture with a late herbicide, near GS32, to eliminate extra application cost.. Fungicide recommendations for stripe rust management have been based on disease threshold levels on specific leaves... Recent northern evaluation by QDPI&F, NSW DPI and NGA has confirmed that the most effective management of stripe rust will be achieved by spraying at or just prior to disease becoming evident in a crop...

Liquid nutrients have been commercially applied as foliar sprays on horticultural crops for 100 years and foliar N sprays started seriously in the about 60 years ago when boom sprayers became widely used... Most of the basic research on foliar fertilisers was done more than 50 years ago in glasshouses... I discuss whether conditions in the northern grains region are sufficiently special to justify the use of foliar nitrogen sprays...
