Nitrogen management and yield dynamics of canola locations
Aims

To investigate how different N management strategies affect growth, yield and WUE under different water regimes.

Key messages
  • Grain yield was driven by biomass production rather than harvest index.
  • Timing of nitrogen had relatively little impact on yield or nitrogen response.
  • Nitrogen rate had little effect on total crop water use.
  • Nitrogen use efficiency and water use efficiency were improved with additional water availability (irrigated treatment).
