Nitrogen Use Efficiency Trial – N Timing (Peechelba East) locations
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 18.28t/ha there were no significant differences in header grain yield from varying nitrogen rate or timing of prilled urea (46%N).
  • Where no nitrogen was applied early in the season a significant decrease in nitrogen content was observed in the stalk of the plants at harvest, but there no influence on grain N content.
  • Test weight was significantly reduced when only 207kg N/ha was applied to the crop, there was no significant benefit in test weight when the highest rate of nitrogen was applied.
