Canola responded to nitrogen fertiliser input across the dune-swale at Karoonda locations
Aims

To evaluate options to manage risk in canola crops without yield penalty, such as:

  • Delaying nitrogen inputs
  • Optimising nitrogen inputs according to soil type and management history
  • Optimising sowing date (while keeping canola at the very beginning of the sowing program)
Key messages
  • Time of nitrogen application was not as important as the quantity available to the plant.
  • Nitrogen is an important driver of canola yields across dune-swale soil types and must be managed in the low rainfall zone for the crop to be profitable.
