- Intervention effect Nitrogen at tillering raised grain yields through more spikes and spikelets per spike.
- Intervention effect Nitrogen at tillering increased spike populations and mean spikelets per spike.
- Intervention effect Nitrogen at tillering generally lowered mean grain dry weights.
- Intervention effect Low rates of nitrogen at tillering reduced grain content.
- Intervention effect Nitrogen during spikelet growth tended to reduce spike populations.
- Intervention effect Nitrogen during spikelet growth depressed spikelets per spike and mean grain weight without nitrogen at tillering.
- Intervention effect Nitrogen during spikelet growth increased these components when high nitrogen was applied at tillering.
- Intervention effect Nitrogen at tillering generally increased grain nitrogen content and nitrogen yield.
- Intervention effect Nitrogen at tillering had little influence on grain yield.
- Association Seeding rate increments changed yield components.
- Association Spike populations increased linearly with seeding rate.
- Association Mean spikelets per spike declined with seeding rate, especially with lower nitrogen.
- Mechanism Nitrogen appeared limiting for grain set at low seeding rates.
- Mechanism Assimilates appeared limiting at higher seeding rates.
