| Fertiliser |
11 kg P/ha, 11 kg S/ha, 27 kg K/ha and foliar Zn, Cu and Mn to ensure other nutrients were nonlimiting. Fertiliser was applied as 50 kg/ha MAP + 1% Zn at sowing (5kg N) and any additional fertiliser was applied after the crop emerged at 2-4 leaves by top dressing with Urea (at 30 or 80 kg N/ha) on the 21st of June. |
