Effect of sowing date and nitrogen rate on grain yield of six wheat varieties locations
Aims

Aimed at establishing variety responses to sowing dates and different N rates and timings

Key messages
  • Increased nitrogen application rates equated to increased grain yield.
  • Eary sowing had a grain yield advantage of 0.74t/ha averaged accross all varieties and nitrogen application rates.
  • Corack was the highest yielding variety in this trial.
  • Splittimg nitrogen application in the second time of sowing increased grain yield. 
  • Grain protein concentration increased as nitrogen application rates increased.
  • The highest protiens occured at the maximum nitrogen rate of 160kg/ha in Lancer, EGA_Gregory and SPitfire from the 12th May sowing.
