Yield response of canola and wheat to nitrogen application – Tamworth 2017

Abstract

Key findings •• Results from this study highlight the yield responsiveness of canola to nitrogen (N) application. •• Canola yield increased with higher rates of N application before the yield response plateaued at 425 kg N/ha. •• Compared to canola, wheat was not as responsive to increasing rates of N, with the response plateauing at 100 kg N/ha. •• Canola protein levels increased with higher rates of N, however, there was an inverse relationship between oil concentration and increasing rates of N. •• Wheat protein levels were almost linear in response to N applications up to 225 kg N/ha, increasing from 10% to 12.6%.
