Late nitrogen application to increase grain protein in barley locations
Aims

To measure increases in grain protein in various barley varieties at flowering with different amounts of applied nitrogen.

Key messages
  • Commander was the only variety which did not meet the minimum protein of 9%.
  • 50kg/ha Urea was required to increase Commander’s protein into the malt range from 8.6 to 9.7%.
  • To increase grain protein by 1%, 10kg/ha Urea is required for every tonne of expected yield.
  • For example, a 5t/ha crop requires at least 50kg/ha Urea. applying nitrogen (N) later in the season, when the yield potential is relatively certain, knowing the N (available soil N, mineralisation and applied N) available to the crop, will help refine the amount of N required.
