Other claims from this paper (8)
- Intervention effect Irrigation significantly and positively increased maize biomass yield compared with rainfed conditions.
- Intervention effect Crop rotation with legumes increased soil nitrogen and carbon content in maize fields.
- Intervention effect Crop rotation with legumes gave a higher maize yield than continuous maize, by 11.1 dt ha−1 y−1 on average.
- Intervention effect The significant effect of crop rotation on the yield of the following maize crop continued after two 4-year rotation cycles.
- Intervention effect No-tillage gave significantly lower maize yield than plow tillage, from 3 years onward.
- Intervention effect Tillage significantly positively affected maize yield from the fourth year.
- Observation Irrigation had the most relative importance as a management factor compared with tillage and crop rotation.
- Observation The two-way interactions between rotation, tillage and irrigation were significant only in extremely dry years.
