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.

Intervention effect Rice yield was highest in the 90-hill plot.
Intervention effect Rice yield above 120 hills was lower than in the 90-hill plot.
