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!
No observed climate data available for this trial. Derived climate data is
determined from trial site location and national weather sources.
