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...

Trials provide success tips for canola.. For example, where seed was placed 5cm deep, the establishment of ATR-StingrayA was reduced by 45 per cent compared with the 2.5cm sowing depth, but there was no establishment reduction for Pioneer 44Y84 CL ( Figure 1 )... Where seed was placed 7.5cm deep, the establishment of ATR-Stingray was reduced to 12 plants/m (20 per cent) compared with 30 plants/m for Pioneer 44Y84 CL (50 per cent)...

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...

Hybrids generally have larger seed than open pollinated varieties... In 2012 trials were conducted across northern NSW to investigate the effect of sowing depth, fertiliser rate and retained stubble on the establishment of several hybrid and open pollinated canola varieties... The paper reports only one season's trial data; there are several consistent messages from the trials across the northern region...

Varieties listed in the paper are covered by PBR... At both 77 and 101 mm, Fleet showed the least reduction in emergence, followed by Buloke, Commander and Schooner... Overall, the results emphasise the need to sow varieties that have short coleoptiles at shallow depths and to take care with seed grading and the use of seed dressings...
