The aim of this trial was to investigate the effect of variety selection, sowing rate and sowing depth on canola establishment in marginal soil moisture conditions in the Southern Mallee.
• Marginal rainfall events result in false germination and patchy establishment.
• In marginal moisture conditions, it is better to sow shallow rather than deep.
• Hybrid varieties are less sensitive to sowing depth than open pollinated.
• Sowing too deep (> 30 mm) reduced yield.
