High yielding barley - nitrogen modelling at Kendenup locations

Aims

To investigate the effect of seeding rate and nitrogen program (application rate and timing) on grain yield and quality to reduce the yield gap in the high-rainfall zone where there is high yield potential.

Key messages

Yield and quality response to nitrogen program and seeding rate was difficult to observe due to moisture stress throughout grain-fill.
Seeding rate had no significant effect on grain yield or quality.
Nitrogen program significantly affected N uptake and grain protein, but not yield or other quality parameters. Grain protein was very high overall.
