Effect of Reduced Tillage on Soil Properties and Cowpea Yield in Rainforest Zone of South West Nigeria

M.A. Awodun
In order to investigate the suitability of zero and reduced tillage methods for cowpea production under a humid tropical condition, the soil properties and grain yield given by five tillage treatments, namely: zero tillage, manual clearing, ridging once, twice and thrice for three cowpea crops were compared. Compared with ridging, zero tillage and manual clearing increased soil nutrient and moisture status. Zero tillage and manual clearing gave higher soil bulk density and lower values of grain yield. Soil bulk density decreased and grain yield increased with increased frequency of ridging.
