Response of Paddy Planted under Butea monosperma Trees in Chhattisgarh

Abstract


Butea monosperma (Lamk.) Taub, locally known as palash is a multipurpose tree species. It yields fibre, dye and fuelwood for local consumption. Studies conducted in Bilaspur district to explore tree- crop interaction undertraditionally natural agroforestry system cleared that the crop parameters of paddy declined towards the bole of thetree. With increasing distance from tree bole these parameters increased. Among crop parameters studied shoot5 1 number was maximum towards the open area (305.6 ± 9.8 m-2) for D and D had minimum towards the tree base5 (205.0 ± 5.2 m-2). Maximum (12.6 ± 0.40 Mg ha-1) shoot biomass was observed for D (open area), followed by4 3 2 1 D , D , D and D . Grain yield also increased with increasing distance of crop from the tree base and was highest5 for D (5.2 ± 0.20 Mg ha-1). As the component plant species in agroforestry system depend on the same reserve ofgrowth resources such as light, water and nutrients and hence there will be influence of one component of a systemon the performance of the other components as well as system as a whole. It can be speculated that along withcompetition, this decrease may be due to the decreased availability of light.
