Other claims from this paper (13)
- Intervention effect Farmer-selected intensification practice (FIP) significantly increased rice grain yield by about 12% over farmers’ practice.
- Intervention effect RAP with NPK application produced about 33% extra yield over farmers’ practice.
- Observation RAP gave the highest mean net income, about USD 220 per hectare.
- Observation RAP+NPK gave the lowest mean net income, about USD 50 per hectare, because of fertilizer costs.
- Association Weeding and fertilization timing contributed most to yield variation among fields.
- Intervention effect Each day of delay in weeding created an average yield loss of 5.3 g m-2.
- Intervention effect Each day of delay in fertilization created an average yield loss of 1.9 g m-2.
- Observation Exploitable yield gap averaged 24% across treatments.
- Observation Exploitable yield gap averaged 29% under farmers’ practice.
- Intervention effect RAP reduced the exploitable yield gap to 25%.
- Intervention effect FIP reduced the exploitable yield gap to 26%.
- Intervention effect RAP+NPK reduced the exploitable yield gap to 12%.
- Recommendation Farmers with good water management should combine timely weeding with other crop management practices to realize yield gains.
