Aim to sow large (>5 g/1000 seeds) canola seed to achieve adequate establishment rates from early sowing... Hybrid vigour (heterosis) has an indirect effect (larger seed size) and a direct effect (enhanced vigour) on canola establishment.. The results reported have greatest relevance for an early planting opportunity and a lesser relevance for canola that is dry sown or planted into moisture in May...

Phosphorus application improves grain yield regardless of variety choice, but limit the amount of P applied in direct contact with seed... Due to lack of adequate follow-up rain at both Nyngan and Trangie sites after the in-crop application, only the rate component of 2013 trials is reported ... Although N application can increase grain yield, it may reduce oil concentration in the grain...

Rural Management Strategies consultant Chris Minehan says using Yield Prophet and plant available water capacity mapping to manage nitrogen can be more profitable than applying a blanket rate... Recent research conducted by Rural Management Strategies in New South Wales has found that managing nitrogen separately across varying soil types using Yield Prophet and plant available water capacity (PAWC) mapping can be more profitable than applying a blanket rate of nitrogen due to savings in fertiliser costs... During the 2013 and 2014 winter cropping seasons, the Grains Research and Development Corporation (GRDC) funded trials at Barmedman to demonstrate the use of Yield Prophet and PAWC mapping to improve nitrogen decision-making in wheat and canola...

Early availability to phosphorus is crucial, phosphorus deficiency limits wheat grain yield principally by depressing early growth, leaf emergence rate and maximum rate of tiller emergence (Rodriguez et al. 1999).. Better placement of phosphorus has the potential to increase phosphorus use efficiency in cropping systems on all soil types... Table 1 notes: Mn, Cu, Zn and B are measured in g/tonne (*)...

Sandy, acid soils in high rainfall areas are most prone to potassium deficiency, particularly if cut for hay... Regional nutrient budgets show a progressive drawdown of potassium (K) as it is removed in plant products and, depending on cropping system and soils, there may be a need to consider the role of K. Use of K in Australia declined from 183 kt K in 2003 to 149 kt K in 2011 but did recover somewhat in 2012... Around ten times more K will be removed in hay than grain...
