Nitrogen rate and timing at Conmurra locations
Aims

To assess the impact of applying nitrogen at different rates and timings on grain yield 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
