Other claims from this paper (14)
- Intervention effect Palisadegrass intercropping decreased rice shoot dry matter and grain yield by 11%.
- Intervention effect Guineagrass intercropping decreased rice shoot dry matter and grain yield by 11%.
- Intervention effect Guineagrass intercropping decreased milled rice productivity by 10%.
- Intervention effect Rice grain yield, grain protein and milled productivity increased with nitrogen application rate.
- Observation Palisadegrass dry matter production and second-cut crude protein were greatest in the rice plus palisadegrass system.
- Intervention effect Palisadegrass first-cut production increased with nitrogen up to 80 kg N ha-1.
- Intervention effect Guineagrass first-cut production increased with nitrogen up to 80 kg N ha-1.
- Intervention effect Palisadegrass second-cut production increased linearly with nitrogen.
- Intervention effect Guineagrass second-cut production increased linearly with nitrogen.
- Intervention effect Rice-palisadegrass intercropping at 80 kg N ha-1 had the greatest land equivalent ratio, 1.96.
- Intervention effect Rice-guineagrass intercropping at 80 kg N ha-1 had the greatest land equivalent ratio, 1.55.
- Intervention effect Relative nitrogen yield of rice-palisadegrass was greatest at 120 kg N ha-1, at 220%.
- Intervention effect Relative nitrogen yield of rice-guineagrass was greatest at 120 kg N ha-1, at 173%.
- Recommendation The authors conclude that forage intercropping systems are economically and environmentally more favorable despite greater grain yield under rice monocropping.
