e0“The inverse relationship especially after subsoiling was due to enhanced root penetration and soil water uptake that led to healthier and leafier crops hence higher water uptake through transpiration leading to depressed soil moisture content.”

Other claims from this paper (7)
- Intervention effect Subsoiling increased maize grain yield by 200% in the short rains of 2009 relative to cover crop without subsoiling.
- 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.
- Recommendation The study highlights subsoiling and soil surface modification as important management practices for maize productivity under erratic rainfall.
