Other claims from this paper (16)
- Intervention effect Zero tillage in rainy and winter seasons reduced weed dry matter about as well as conventional tillage.
- Intervention effect Zero tillage in rainy and winter seasons produced maize and system yield about as well as conventional tillage.
- Intervention effect Conventional tillage in rainy and winter seasons (CT-CT) and in rainy season with zero tillage in winter (CT-ZT) reduced weed density and weed dry weight in wheat.
- Intervention effect Conventional tillage in rainy and winter seasons (CT-CT) gave higher wheat grain yield than the rest of the tillage sequences.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased maize grain yield by 51.78% over the weedy check.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased net return of maize by 61.96% over the weedy check.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased wheat grain yield by 18.40% over the weedy check.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased net return of wheat by 17.23% over the weedy check.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased system yield by 31.78% over the weedy check.
- Intervention effect Integrated weed management in both crops (IWM-IWM) increased net return of the system by 34.96% over the weedy check.
- Intervention effect Zero tillage with or without residue improved soil pH, organic carbon and CO 2.
- Intervention effect Zero tillage with or without residue improved dehydrogenase activity in soil.
- Intervention effect The recommended herbicide sequence (RH-RH) gave a significantly higher benefit-cost ratio.
- Intervention effect IWM-IWM improved soil CO 2 and dehydrogenase activity relative to RH-RH sequences.
- Association Long-term zero tillage farming causes important yield losses.
- Observation Water infiltration rates were higher.
