HYC 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 (cv RGT Accroc).

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 Research Centre) .
- To assess the value of adding increased P, K, and S when targeting higher yield potential rather than N alone.

Key messages

 Nutrition treatments had no effect on harvest dry matter, grain yield, test weight or screenings.
 Based on the grain protein and yield of the unfertilised plots which received 100kg/ha MAP (10N), the unfertilised plots removed 225kg N/ha from the soil for the N present in the grain.
 If it is assumed that 75% of the N in the canopy resides in the grain with 25% in the straw and chaff, then it is assumed the crop removed 299kg N/ha from the soil to grow the crop.
 The trial indicated that additional N, P and K applied in this trial did not increase yield with a trend (not significant) for N application to reduce grain yield and harvest dry matter.
 With grain protein at 12.5% in the unfertilised plots there was a significant increase in protein when 150 – 240N was applied.
 Although not significant, the 0N and 120N treatments were the only treatments to achieve grain yield >10 t/ha.
