A profitable canola crop can be grown from March seeding. Early sown canola had normal growth and development, albeit starting to flower earlier. There was a longer flowering period with earlier sowing time, for all varieties. This is likely to be a key contributor towards potential yield.
In this trial, the highest yields and gross margins were achieved from the early April seeding of InVigor T4510 (2.04 t/ha) and ATR Bonito (1.90). Yields from earlier (March 8) and Later (April 29) sowing were similar to each other, although lower than TOS2. Yields were severely reduced by seeding on May 24.
The early-mid varieties had highest overall yields and proved to be more adaptable than the long season varieties. The early-mid varieties had similar yield to the longer maturity varieties with March sowing, but significantly outyielded them for April sowing. This indicates there may be no need to source long season varieties for early sowing in this short season environment.

Plots were sown with 100 kg/ha Agras Xtra, and 50kg/ha urea top-dressed. A further 35 kg/ha urea was applied at 4WAS and 70 kg/ha at 7WAS. The total nitrogen application was approximately 85 kg/ha. |
