Other claims from this paper (8)
- Intervention effect First-year converted plots had better rice growth than long-term direct sowing plots.
- Intervention effect First-year converted plots had better rice yield than long-term direct sowing plots.
- Association The first-year growth and yield advantage was more apparent in well-drained fields.
- Intervention effect Conversion increased total inorganic available nitrogen in soil early in the first year.
- Intervention effect Conversion decreased soil nitrate nitrogen early in the first year.
- Intervention effect Postharvest direct sowing soil drained and harrowed more easily and had more porosity than transplanted soil.
- Observation The soil physical properties of direct sowing appeared in the first year after conversion.
- Recommendation The authors concluded that alternating direct sowing and transplanting could counter the yield decline.
