Sum16-21 N x K on canola


To investigate the response of canola to potassium (K) and nitrogen (N) rates.
Yield and grain quality can be limited if either of these macro nutrients is in short supply.

Fig 2: Yield response to N & K


  • Bonito canola showed significant responses to both N and K at this site.
  • Supplying 60 kg/ha of N and 25kg/ha of K was the best strategy for optimising returns under these conditions.
