Aims

To evaluate the influence of different rates and timings of 46 %N prilled urea applied N prior to later applications of liquid N applied as fertigation applied in grain maize.

Key messages
  • With an average grain yield of 17.29t/ha there were no significant differences in header grain yield from varying nitrogen rate or timing of prilled urea (46%N) when 230 kg N/ha was applied as fertigation post sowing.
  • Dry matter was between 30 and 35t/ha at harvest with approximately 50% of this dry matter present as grain and the remaining 50% as stover.
  • In terms of nitrogen uptake in the crop at harvest 70% of the N on average was in the grain with 30% in the stover (leaves, stalk and cob husk).
  • There was some evidence that additional N increased grain N content, but this was not associated with yield increases.
  • The trial results are similar to the same trial run in 2019/20 which following oaten hay had an average yield of 18.2t/ha compared to 17.3t/ha when sown maize on maize.
