Abstract
The allelopathic effects of Eucalyptus camaldulensis Dehnh. and its control by farmyard manure was subjected by the application of different concentration of aqueous leachate of leaf litter and with the combined effects of E.camaldulensis litter leachate and farmyard manure through different dilutions. The experiment was carried on by the examined seed germination, seedling growth of green gram (Vigna radiata) (L.) Wilczek growing in plate culture. Different concentrations of aqueous leachate of Eucalyptus (Eucalyptus camaldulensis) litter affect differently along with different concentrations of farmyard manure (FYM). The investigations showed that E.camaldulensis leaf litter extract (leachate) had inhibitory effects on the growth of different parameters of vigna radiata. It was also observed that the combined effects of litter and farmyard manure markedly reduced the inhibitory effects of leachate and thus increased the growth of gram. The results suggested that if Vigna radiata L. is to be cultivated in an agricultural land surrounded by E. camaldulensis trees, its growth rate may be enhanced by the application of FYM. In the absence of FYM, Vigna growth is significantly arrested due to allelopathic effect of E. camaldulensis leaf litter.
