Aims

To test canola and wheat yield response and the interactions between nutrients where N, P, K and S and micro-nutrients Zn and Cu are omitted.

Key messages

• National GRDC funded project ‘Optimising the yield and economic potential of high input cropping systems in the high rainfall zone’.
• Two nutrient omission trials sown in 2016 at Bool Lagoon to test canola and wheat yield response and the interactions between nutrients where N, P, K and S and micro-nutrients Zn and Cu are omitted.
• Relative to the treatment supplied with non-limiting nutrients, both canola and wheat grain yields were significantly lower if either P or S were not applied at sowing (38 and 30 % depression respectively for canola, 24% and 17% for wheat).
• Relative to the treatment supplied with non-limiting nutrients, canola biomass at flowering was 36 % lower without in-crop N and 8% lower without P at sowing, while wheat biomass at flowering was 40% lower without in-crop N and 12% lower without P at sowing.
