| Abstract | A study carried out in the tree nursery of College of Forestry, Vellanikkara,<br/>Thrissur to assess the autoallelopathic effect of selected multipurpose trees and the<br/>effect of their leachate on agricultural test crop. The study on allelopathy is very<br/>essential in agroforestry as it effect the yield and performance of the trees and crops<br/>grown together and is essential to make judgment on the compatibility of trees and<br/>crops. The allelopathic effect of different tree part leachates such as leaf leachate,<br/>bark leachate and root leachate of selected trees viz., Acacia auriculiformis, Acacia<br/>mangium, Ailanthus. triphysa, Grevillea robusta and Swietenia macrophylla on the<br/>germination and growth of their own seedling and an agricultural test crop cowpea<br/>(Var. Anaswara) were studied. The soil for the pot culture experiment was collected<br/>from well established plantations of the MPTs and is used as potting mixture with<br/>sand in equal proportion. The pots were irrigated with leachates of different tree parts<br/>of these trees by soaking the tree part in water for 24 hours in 1:10 w/v concentration.<br/>The monthly variation in nutrient status of the soil used for pot culture experiment<br/>and the variation in the physicochemical properties of leachates at six intervals is also<br/>estimated.<br/>The effect of tree part leachates considerably varied among the germination<br/>and biomass production in both allelopathic and autoallelopathic studies. The<br/>observations on the germination per cent in allelopathic and autoallelopathic study<br/>revealed greater inhibition in the pots treated with leaf leachate in all tree species,<br/>except for S. macrophylla. With regard to biometric observations and biomass<br/>production also, S. macrophylla performed as the best compared to other selected<br/>species investigated for autoallelopathy. In case of the test crop also, it showed a<br/>better growth in pots treated with the leachates from S. macrophylla.<br/>The physicochemical analysis of the leachate of tree parts used to irrigate the<br/>pots showed increasing trend in total solid, electrical conductivity, total phenol, total<br/>carbohydrate and a decreasing trend in pH upto 36 hours. The physicochemical<br/>analysis of leachates for total phenol showed a greater concentration in the leaves<br/>than the bark and root.<br/>Results converge to the generalisation that among the five selected tree<br/>species the effect of auto allelopathy is negligible in case of S. macrophylla. The<br/>better growth performance of the test crop in S. macrophylla tree part leachates shows<br/>the compatibility of the test crop with the tree than the other selected tree species.<br/> |
