e0“relative to cover crop without subsoiling treatment interaction, subsoiling led to 200 and 228% increase in maize grain yields during the short rains season of 2009 (SR09) and long rains season of 2010 (LR10) respectively (significance p=0.05)”

- Intervention effect Subsoiling increased maize grain yield by 228% in the long rains of 2010 relative to cover crop without subsoiling.
- Association Grain performance was inversely related to soil moisture at 30 cm depth.
- Intervention effect Subsoiling with cover crop had consistently low soil moisture across both seasons.
- Intervention effect Mulching had consistently high soil moisture across both seasons with or without subsoiling.
- Mechanism Low soil moisture without subsoiling was probably due to roots being unable to access deeper soil horizons.
- Mechanism Enhanced root penetration and water uptake after subsoiling were interpreted to produce healthier, leafier crops and depress soil moisture through greater transpiration.
- Recommendation The study highlights subsoiling and soil surface modification as important management practices for maize productivity under erratic rainfall.
