Should high nitrogen rates be applied to boost cereal protein in the Esperance Port Zone? locations
Aims

To optimise cereal protein by better understanding response to high nitrogen rates in a given season through demonstration trials while also better understanding disease response.

Key messages
  •  Grower practice N rates at both sites were the most economical
  •  Applying higher rates of N to maintain or increase protein was not profitable if yield did not also increase
  •  Grain markets should be watched in case higher quality grades fetch significantly higher prices
  •  Increased nitrogen can lead to increased incidence of powdery mildew if not controlled early in the season.
