Nutrition for Hyper Yielding Wheat locations
Aims

To assess the value of higher nutrition input (N, P, K & S) for wheat in the growing season and as an “N bank” for the following season.
Individual objectives specific to the trials were:
- To assess the value of additional nutrients in the growing crop (set up as small plots at the HYC Research sites) and for the following crop (mirror image trial set up in the host farmer’s surrounding paddock).
- To assess the value of adding increased P, K, and S when targeting higher yield potential rather than N alone.

Key messages

• There was no response above the standard N input of 148kg N/ha, which also included a standard of 100kg/ha MAP at sowing (10N, 21.9P).
• Protein levels in the standard control were increased from 9.7% to 11% with additional N application but the increases were not associated with higher grain yields.
• At harvest there was no evidence of dry matter increases associated with greater nutrition input.
• Test weight was unaffected by the nutrition strategy in this trial, but there was a very slight increase in screenings.
