Other claims from this paper (12)
- Intervention effect In wet seasons, CF grain yield was 15–20% above organics in the first two years.
- Intervention effect Wet-season OF yields later improved to 4.8 to 5.4 t ha−1, comparable with CF and INM.
- Intervention effect In dry seasons CF outyielded OF for four consecutive years, with parity in the fifth.
- Intervention effect In dry seasons INM outyielded OF for four consecutive years, with parity in the fifth.
- Observation N and P partial nutrient balances were positive and greater with OF and INM than CF.
- Observation K partial nutrient balance was positive with OF but negative with CF and INM.
- Intervention effect After five years OF raised soil organic carbon by 50–58% over CF.
- Intervention effect After five years OF raised available N by 3–10% over CF.
- Intervention effect After five years OF raised available P by 10–30% over CF.
- Intervention effect After five years OF raised available K by 8–25% over CF.
- Intervention effect The soil sustainability index was maximal under organics at 1.63, versus 1.33 under CF.
- Recommendation Organic farming needs more than two years to stabilize rice productivity and improve soil quality and sustainability.
