- Intervention effect Conventional tillage retained 10–31% more moisture than conservation agriculture on sand.
- Intervention effect Conventional tillage retained 27–40% more moisture than conservation agriculture on clay.
- Intervention effect The mulched conventional tillage intercrop retained the most soil moisture.
- Intervention effect On sand in the wetter season, maize intercrop yield was highest under conservation agriculture at 2.3 Mg ha−1.
- Intervention effect On sand in the wetter season, maize intercrop yield was lowest under mulched conventional tillage at 1 Mg ha−1.
- Intervention effect On clay, the mulched conventional tillage intercrop gave the best maize yield at 2.4 Mg ha−1.
- Intervention effect In drier seasons, mulched conventional tillage gave the best maize intercrop yield on clay at 1.4 Mg ha−1.
- Intervention effect Mulching raised maize grain yield by 55–90% in drier seasons.
- Intervention effect Mulching lowered water use efficiency about 15% in the wetter season.
- Observation Cowpea grain yield remained at or below 1 Mg ha−1 in both monocrop and intercrop over three seasons.
- Recommendation The authors recommend tillage and mulching choices by soil type to reduce rainfall variability effects on productivity.
