Nitrogen rate and timing at Conmurra locations
Aims

To assess the impact of applying Nitrogen at different rates and timings on grain yields of selected wheat varieties.

Key messages
  • The influence of nitrogen on grain yield and protein depends on the amount of fertilizer applied, the timing and the growing season.
  • Fertilising to increase grain protein is profitable if farmers are being paid a premiums for protein above 10.5 -11%.
  • Multiple wheat varieties responded to nitrogen when applied at GS31, particularly at the high rate of 100 kg/ha.
  • A 7.2% yield increase was observed by treating SQP-Revenue with fungicide
