Maize nitrogen application rate × hybrid under irrigation – Breeza 2014–15 locations
Aims

To compare grain yield responses with variations in three maize hybrids and six nitrogen rates under raised-bed flood irrigation at Breeza on the Liverpool Plains.

 

Key messages
  • There was no difference in the yield performance of the three hybrids. Differences between the hybrids were evident for cob number and grain quality only.
  • The highest maize yields were obtained from the 150 kg N/ha, 200 kg N/ha at sowing and the 75:75 kg N/ha split nitrogen (N) treatments, which all produced similar yields.
