To determine the optimum combination of sowing date, nitrogen management and variety for growth, grain yield and oil concentration in Canola.
• Highest yields were obtained when flowering started in early to mid-August. Treatments that flowered in July were affected by frost and treatments that flowered in September were affected by heat and drought.
• The strongest yield response to nitrogen was on treatments that flowered in early to mid-August.
• Hybrids tended to recover better from frost damage than open-pollinated (OP) triazine tolerant (TT) varieties, but flowering date and nitrogen management were more important to maximise yield potential than variety type.
• The highest oil concentration was obtained from varieties that flowered in early to mid-August.
Although rainfall was low and frost incidence and severity was high in 2017, canola was still a productive option for growers. The yield response from correctly matching sowing date with phenology was the main message from 2017, reaffirming a consistent result from canola research conducted in recent years. Growers are advised to aim to have crops flowering close to the optimum start of flowering date for the environment in which they are grown; these dates are summarised in the E-Book 10 tips for early sown canola (Lilley et al. 2017). Secondly, benefits are obtained by managing the crop with optimum nitrogen fertility. Finally, with those factors in place, hybrid varieties can take grain yield to the next level, but varietal choice is not a ‘silver bullet’ in isolation.
