Inhibitory effects of Mangifera indica L. leaf leachate on Pennisetum glaucum. L. (Pearl millet) growth.

Abstract

The given experiment was laid down to evaluate the allelopathic effect of Mangifera indica L. (mango) aqueous leaf leachate on physical growth of Pennisetum glaucum (Pearl millet). Leaf leachate in ratio of 5:100, 10:100 w/v (leaf : water) were supplied to 6 days old healthy plants of Pennisetum glaucum (Pearl millet) while control plants were irrigated with normal water. The leaf leachate of M. indica exhibited dose dependent effect as stimulatory as well as inhibitory on shoot and root elongation and also on dry matter of treated plants. The concluded result also indicated the allelopath inhibition was significantly pronounced at high concentrations of applied leachate (10%) with shoot and root length as well as with dry weight accumulation over control treatment, while the low concentration was found as less inhibitory for plant growth.
