Can we economically increase grain protein at flowering? locations
Aims

To increase grain protein (%) in wheat and barley by means of late applications of nitrogen (N) applied as UAN.

Key messages
  • N applications at flowering in 2012 increased grain protein (%) in barley and improved grain quality, but were not economically viable. In the Wimmera, 20kg N/ha/t grain at flowering time increased grain protein by 1% in wheat.
  • Applying UAN late (GS65) in wheat did not increase grain protein and resulted in no economic returns.
