Other claims from this paper (14)
- Intervention effect High N lowered grain yield relative to normal N in both rice types under dry cultivation and paddy rice under moist cultivation.
- Intervention effect High N raised upland rice grain yield under moist cultivation.
- Intervention effect Increasing N raised productive tillers in both rice types.
- Intervention effect Increasing N changed spikelets per panicle variably.
- Intervention effect Increasing N lowered ripened grain percentage in both rice types, more in paddy rice.
- Intervention effect Upland rice grain weight did not differ significantly across N levels.
- Intervention effect Dry cultivation did not significantly change upland rice grain weight.
- Intervention effect Dry cultivation significantly decreased paddy rice grain weight.
- Intervention effect Dry cultivation increased ripened grain percentage in both rice types, more in upland rice.
- Observation Upland rice had fewer adventitious roots and weaker nitrogen absorption and productive tillering than paddy rice.
- Observation Upland rice had fewer panicles and spikelets and lower yield than paddy rice.
- Observation Upland rice showed a quicker rise in adventitious roots and slower decline in leaf nitrogen from jointing to heading.
- Observation Upland rice showed faster postflowering chlorophyll decline.
- Observation Upland rice had less negative response to water stress and more positive response to N.
