To compare 5 fertiliser application regimes commonly used in barley in a replicated trial.
Application of DAP fertiliser at time of sowing improves yield in barley. Application of additional nitrogen lifts yields further, and improves protein levels in the grain. Results suggest efficiencies in nitrogen application can be achieved with placement in the root zone compared to surface application. Further work needs to be undertaken to better understand the process.
