Chasing high yields with high rates of nitrogen - what happened in 2014? locations
Aims

To investigate variety specific responses to applied N.
 

Key messages
  • Application of nitrogen fertiliser significantly increased yield compared to no fertiliser.
  • Grain protein results suggest that in 2014 nitrogen was not the limiting factor to yield especially at the higher rates; incremental increases in mean grain protein were recorded with each increase in N, up to 300 kg N/ha.
  • Variety choice had a significant effect on final grain yield and protein, however individual variety response to applied N rates were relatively similar.
  • There was a strong link between N rate and what was left in the soil after harvest, and the higher rates left a considerable amount.
