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.
