In the present study, the allelopathic potential of Phyllanthus amarus (L.) Schum and Thoun. on seed germination and seedling progress of Vigna mungo (L.) Hepper. Var.CO. 653. Leaf and stem aqueous extracts of Phyilanthus amarus at 5, 10, 15, 20 and 25% concentrations were applied to produce their conclude on seed germination and seedling development of trial plant under laboratory conditions. Germination and seedling development trails were performed as CRD (Completely Ranndomized Design) with 3 replications. The aqueous (water) extracts from leaf and stem had inhibitory cause on seed germination of Phyllanthus amarus. The effects noted that the extracts brought about substantial inhibition in the germination of Vigna mungo seeds and in the development of its shoot length and root length extracts of Phyllanthus amarus declined the seed germination of Vigna mungo with raise in the extracts concentrations. The extracts also suppressed the root length, shoot length and dry weight of Vigna mungo seedling with raise in the extracts concentration compared with manage treatments. Aqueous extract of leaves noted the extreme inhibition while stem notable the minimum effect on Vigna mungo. These determination revealed that the inhibitory produce potency be due to the presence of the allelopathic phytochemicals in the extract of Phyllanthus amarus from the current study. Phyllanthus amarus leaf extracts were highest detrimental than stem extracts. The fact obtained could be utilized in the improvement of bioherbicide for future in the field.
