Abstract

Abstract Field experiments were carried out to study the effect of three tillage depths (5, 15 and 30 cm) on soil physical properties and on yield of maize ( Zea mays), sorghum ( Sorghum bicolor) and cotton ( Gossypium hirsutum) on a ferruginous tropical soil. The increase in porosity due to deep tillage was only temporary and differences in water storage and movement were only noticeable during the early part of the rainy season. Deep tillage increased the yield of maize and cotton by about 10% but sorghum yield was not affected.
