Nitrogen response of six wheat and four barley varieties across two sowing dates – Nyngan 2016 locations
Aims

To investigate nitrogen response of six wheat and four barley varieties across two sowing dates.

Key messages
  • The experiment was highly responsive to nitrogen application (N).
  • Averaged across the two sowing dates, yield ranged from 0.89 t/ha in LRPB DartA without applied N to 4.95 t/ha in LRPB FlankerA with the highest application rate of 160 kg N/ha.
     
Nyngan NSW 2016 Barley

Ten varieties × 6 N rates × 2 sowing dates. Three replicates of each treatment blocked for sowing date with N rate and variety randomised within these blocks.
