Abstract:

The present study was carried out in Navsari Agricultural University Navsari, Gujarat, India, intended to analyze the phytochemicals in leaf litter of Indian lilac (Melia azedarach L.) and to examine its allelopathic influence in leaf aqueous extract and leaf litter form on two pulse crops. The phytochemicals in leaf litter of Indian lilac were analyzed through Gas chromatography mass-spectrometry (GC-MS). The allelopathic influence of leaf aqueous extracts (control, 25, 50, 75 and 100% concentration) and leaf litter (control, 5, 10, 15 and 20 g/pot) on germination and initial growth, and biomass of green gram (Vigna radiata L.) and black chickpea (Cicer arietinum L.) was carried out in laboratory and in pot culture. To comprehend the allelopathic effect of leaf litter on later stages of growth, biomass and grain yield of test crops, separate pot experiments were conducted. GC-MS analysis revealed different compounds like phenolic acids and their derivatives, alkaloids, methyl ketones (volatile allelochemical), unsaturated fatty acids, omega-3 fatty acid, benzofuran, propargyl acid, benzoxepine, fluorobenzoic acid, silicyclobutane, palmitic acid in leaf litter of M. azedarach. The leaf aqueous extract and leaf litter inhibited the germination, germination rate index, initial growth, and biomass of green gram and black chick pea in laboratory and pot culture bioassays. However, the results of pot experiment carried out till maturity of test crops showed no significant allelopathic effects of leaf litter on growth, biomass and grain yield. Thus the allelopathic effect of detected phytochemicals was fleeting in nature and it may have diminished with passage of time in pot soil due to volatilization.
