Other claims from this paper (11)
- Intervention effect No-tillage, residue retention and crop rotation/intercropping maintained higher soil organic carbon and total soil N than conventional tillage after four years.
- Intervention effect Soil bulk density was higher under no-tillage than under conventional tillage after four years.
- Intervention effect Tillage and cropping systems did not differ significantly in maize or soybean yields in the first three seasons.
- Intervention effect In the fourth season, crop rotation (CT maize after soybean) increased maize yield by 49% compared with NT maize.
- Intervention effect Averaged across farmers, CT cropping systems increased maize and soybean yield by 23 to 39% compared with NT cropping systems.
- Observation Maize yield in farmer-managed trials ranged from 520 to 2700 kg/ha under CT.
- Observation Maize yield in farmer-managed trials ranged from 300 to 2000 kg/ha under NT.
- Intervention effect NT systems reduced the cost of producing maize or soybean by 20 to 29% compared with CT practice.
- Intervention effect NT systems gave higher returns to labor than CT practice for maize or soybean.
- Intervention effect NT cropping systems were more profitable than CT systems, as shown by benefit-to-cost ratios.
- Recommendation Conservation agriculture with NT, crop rotation, intercropping and residue retention is a win-win scenario for maize and soybean.
