To understand the risks and rewards of sowing canola early, in particular, the risks associated with March sowing and how it impacts crop establishment, growth and yield.

Key Messages

• Sowing canola in March resulted in no yield penalty, unlike sowing in May, which had significantly lower yields (P < 0.05).
• While March sowing led to significantly lower plant densities (P < 0.05), this did not translate into reduced yields, highlighting the crops’ ability to compensate.
• Earlier sowing emphasises phenological differences of varieties vernalisation requirements influencing peak flowering periods.
