To examine the nitrogen use efficiency of canola grown under overhead irrigation
• Seed yield was not significantly different across the treatments receiving 120 kg N/ha or higher.
• Plant biomass and accumulated N differences were beginning to show at early flowering (4.89t/ha mean) and significantly less N in the unfertilised plots (75.5kg N/ha).
• Optimum yield of 4.19t/ha was produced from a crop canopy of 16.8t/ha biomass that had an N content of 245kg N/ha.
• Applying a rate of 120 kg N/ha or higher had no additional effect on harvest biomass or accumulated N content of the canopy.
• Application N fertiliser had no influence on oil content and test weight.
• While there was variation in the Harvest Index from 0.26 to 0.22, the differences were not statistically different.
• Water use efficiency was 9.7 kg/mm. Nitrogen use efficiency was 58.5kg N/t of grain.
