Nitrogen nutrition for hyper-yielding canola locations
Aims

To determine optimum nitrogen nutrient management (including rate and timing) for hyper-yielding canola.

Key messages

 All nitrogen treatments yielded more than nil N and 100% Upfront (all N applied at sowing) treatment.
 N was possible lost from denitrification just after sowing as the site became waterlogged.
 There was no yield difference between nitrogen timing for all treatments applied after sowing.
 Oil concentration was highest where nil N was applied.
 A nitrogen trial will be sown in 2021 with the inclusion of a winter cultivar.
