Do high inputs always lead to high returns? locations
Aims

A high input trial was created in 2012, with the aim of demonstrating that a crop will continue to respond to nitrogen if the season is suitable, leading to higher yields.

Key messages
  • The highest yielding plots were the ‘Medium’ input which was 150kg urea at tillering and 100kg/ha urea at stem elongation.
  • The High input plots were the lowest yielding.
  • Protein levels were directly related to nitrogen at stem elongation.
  • Nitrogen response is varied depending on timing of application so make decisions wisely!
