Other claims from this paper (11)
- Observation Almost all farmers used herbicides to control weeds in dry-seeded rice, and weed control is a major challenge.
- Intervention effect Farmers who grew a non-rice crop before the rice season had better weed control than those who did not.
- Intervention effect Ploughing intensity and the type of implement used for land preparation were not significant factors for weed control.
- Association Field bund management was one determinant of productivity differences among farmers.
- Intervention effect Cross-bunds or periphery- and cross-bunds improved the efficiency of rainwater conservation and input use.
- Intervention effect Cross-bunds or periphery- and cross-bunds increased yields.
- Association Fields with higher levelling precision had lower water stress.
- Association Fields with higher levelling precision produced better yields.
- Intervention effect On average a farmer lost 0.93 t/ha of yield because of land-levelling deficiency.
- Intervention effect Dividing large and medium farms into smaller plots improved levelling precision and water control.
- Intervention effect Dividing large and medium farms into smaller plots resulted in higher yields.
