Other claims from this paper (7)
- Observation Only early grown upland rice showed potential for increased productivity.
- Intervention effect Increasing seed density slightly increased productivity under upland direct sowing.
- Intervention effect Increasing nitrogen fertilizer slightly increased productivity under upland direct sowing.
- Intervention effect Higher nitrogen fertilizer slightly decreased productivity under water-logged direct sowing.
- Observation Late-sown Eiko yielded 34.6 kg/a of brown rice at 600 grains per m2.
- Recommendation Late rice cultivation should prevent cool-weather damage by heading within a set time limit.
- Recommendation Increasing main-stem panicles per area should help increase yield in late rice cultivation.
