To understand the risks and rewards of sowing canola early, in particular, the impact on yields and profitability.
2023:
• All six canola varieties sown at the start of April (time of sowing 1, 3 April 2023) had significantly higher yields than all varieties sown at the start of May (time of sowing 2, 2 May 2023).
• The early maturing varieties, Emu and Battalion, performed the best overall.
• 2022 and 2023 trials demonstrate the significant effect time of sowing has on yield and the rewards associated with sowing canola early (if the opportunity arises).
