Abstract
Gas Chromatography Mass-Spectrometry (GC-MS) analysis revealed that leaf litter of Melia dubia contain phenolic acids and its derivatives, unsaturated fatty acid, alkaloids, methyl ketones (volatile allelochemical), aromatic ketone, chromene etc. Further it was reported that the aqueous leaf extracts (0, 25, 50, 75 and 100% concentration) and leaf litter (0, 5, 10, 15 and 20 g/pot) inhibited the germination, growth (shoot length, shoot length and vigour index) and initial biomass (shoot, root and total biomass) of green gram and black chickpea. Percentage of inhibition in germination and initial growth parameters increased with the increasing the concentration of aqueous extract or litter amount of M. dubia. However, pot experiments, carried out till crop maturity, revealed that there was no significant allelopathic effect on growth, biomass and grain yield of the test crops. This indicates that the allelochemicals present in M. dubia leaf litter are volatile in nature and their effect is transient in nature.
