Abstract

A pot culture study was undertaken to investigate the allelopathic effect of leaf lopping of trees, when used as organic sources of nutrient, on the growth and yield of cowpea, maize, groundnut and ragi. The allelopathic effect of various tree leaf loppings varied with different crops. Leaf loppings of all trees except casuarina and mango reduced seed yield in cowpea with the greatest reduction caused by cashew, teak, rubber and cocoa. Leaf loppings of all the trees significantly reduced yield of maize with the maximum reduction caused by portia and cocoa. In groundnut, all trees except sapota and mango significantly reduced the yield with the maximum caused by rubber. In ragi, addition of guava leaf loppings reduced yield most. The study brought out the allelopathic compatibility of the various trees on the test crops.
