Other claims from this paper (11)
- Intervention effect Grain yield increased significantly from 0 to 160 kg hm-2 nitrogen.
- Observation Total spikelets per area increased and accounted for the yield increase.
- Intervention effect N3 reduced grain filling percentage.
- Intervention effect N3 significantly reduced N harvest index and four nitrogen efficiency measures relative to N2.
- Intervention effect Shoot dry weight increased across nitrogen rates.
- Intervention effect Harvest index decreased as nitrogen increased to 240 kg hm-2.
- Intervention effect Flag leaf photosynthesis, zeatin compounds, and grain sucrose to starch enzymes increased up to N2.
- Intervention effect N3 did not improve those leaf and grain physiological measures versus N2.
- Intervention effect Root mass, architecture, oxidation activity and root zeatin compounds increased through N2.
- Intervention effect N3 further increased root mass and length measures relative to N2.
- Association Root oxidation and zeatin levels correlated positively with leaf photosynthesis, zeatin and grain enzyme activities.
