Nitrogen management for wheat protein and yield in Bonnie Rock locations

Aims

To reduce costs in poor seasons and maximise yield in good seasons by having a greater understanding of tactical nitrogen application and how it affects wheat protein and yield.

Key messages

There was no protein or yield penalty in delaying all nitrogen to four weeks after emergence.
Delaying all nitrogen application to 10 weeks after emergence resulted in reduced grain yield due to little follow-up rain.
