To determine optimum nitrogen nutrient management (including rate and timing) for hyper-yielding canola.
ï‚· All nitrogen treatments yielded more than nil N and 100% Upfront (all N applied at sowing) treatment.
ï‚· N was possible lost from denitrification just after sowing as the site became waterlogged.
ï‚· There was no yield difference between nitrogen timing for all treatments applied after sowing.
ï‚· Oil concentration was highest where nil N was applied.
ï‚· A nitrogen trial will be sown in 2021 with the inclusion of a winter cultivar.
