Comparative performance and effect of selected agroforestry tree species on maize productivity in semi-arid Kenya

This study was carried out to determine performance of selected five agroforestry tree species under different treatments and their effect on crop yield in semi-arid (Juja) Kenya. The aim was to correctly pinpoint at what stage of the trees’ growth they start exacting effect on the intercrop and compare what has been reported on some of the experimental trees elsewhere. The specific objectives of the study are; 1. To assess dynamics of growth of the selected agroforestry trees 2. To determine difference in maize yield near and away from the selected trees
