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...

Blackleg and its management has become an important issue for canola in the coming seasons... As most of the canola cultivars, irrespective of the level of their adult plant resistance, are susceptible to infection by the fungus at the seedling stage (may be termed as 'seedling susceptibility window') and consequent canker formation the timing of ascospore release in relation to the onset of adult plant resistance provides information on the risk of blackleg... The risk of blackleg appears to be both location and season specific...

Agriculture is under increasing pressure to develop management practices to minimise P loss... The modelling predicts that depending on location and the benefit from biochar a farmer can spend between $15 and $165 either buying or producing biochar on farm and break-even... In this type of seasons, P fertiliser placed at 14 cm depth remained in moist soil longer than P placed at 4 or 8 cm and was more available for crop uptake later in the season...

KEY poiNtS A range of soil test values used to determine if a nutrient is deficient or adequate is termed a critical range... recent research has highlighted that nitrogen applications can be wasted, even on cropping soils that have low n availability, if the levels of other nutrients such as potassium (K), phosphorus (P) and sulfur (S) are not adequate... The critical wheat soil S test value measured in the 0 to 30cm soil layer is 4.6 (4 to 5.3) mgS/kg for all soils to achieve 90 per_cent of maximum yield...
