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 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 sand at 1.5 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.
