Key messages
  • In this water-limited scenario, with 70 kg/ha N available in the soil at the start of the season, in-crop nitrogen application served to significantly reduce yield relative to the zero N control.
  • Yield depression was strongly significant (p=0.001) when nitrogen was applied at GS30 (start of stem elongation) but was less evident when applied at GS37 (flag leaf first visible).
  • Unusually, the yield reduction from GS30 nitrogen timing was associated with higher grain protein than the later flag leaf first visible (GS37) timing. This result looks likely to have been influenced by protein concentration effect accompanying the stronger yield reduction at GS30.
