Maize nitrogen rate × hybrid responses – Gurley 2014–15 locations
Aims

To compare plant characteristics and grain yield responses of three maize hybrids with varying rates of N applied at sowing or in-crop under dryland conditions at Gurley, south-east of Moree. 

Key messages
  • The trial site suffered from very dry conditions for the first three months after sowing.
  • As a result, final grain yields were very low, averaging 0.3 t/ha.
  • There was no impact from varying nitrogen rate on any aspect of plant growth or grain yield at this site except for cob number per plant.
  • Hybrid selection affected crop yield.
