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.
