To determine optimum nitrogen nutrient management (including rate and timing) for hyper yielding spring canola.
ï‚· A grain yield of close to 6t/ha was achieved where a high rate of nitrogen fertiliser was combined with the application of animal manure to replicate high fertility soils.
ï‚· The manure alone increased yield by 0.75t/ha and raised the bar on our understanding of achievable yield for canola for this environment.
ï‚· Yields responses to granular urea N peaked at 150kg N/ha and similar yields were achieved between 150, 225, and 300kg/ha of applied N.
