Other claims from this paper (9)
- Observation Uniform stands at 30 plants m–2 achieved grain yield above 12 t ha–1.
- Association At about 100 plants m–2, stand distribution had negligible impact.
- Association Grain yield was maintained or increased at lower plant populations.
- Association more tillers per plant was maintained or increased at lower plant populations.
- Association more grains per panicle was maintained or increased at lower plant populations.
- Observation Aerial-sown rice reached maximum grain yield up to 14.9 t ha–1 with at least 100 plants m–2.
- Observation Drill-sown rice reached maximum yield with at least 100 plants m–2 and row spacing no greater than 27 cm.
- Association Large within-row gaps at 36-cm spacing reduced grain yield.
- Recommendation The authors identify 100–200 plants m–2 as a practical optimum for semi-dwarf rice with either sowing method.
