Amaranthus viridis L. is a common wild vegetable and weed of cultivation.The studies indicated that seeds of Amaranthus viridis L. germinated better at25-30 degree C with or without any chemical/ mechanical treatment. Thegermination percentage decreased with increased sowing depth and waterstress. Seeds did not germinate at all the applied levels of salinity. The plantsgrew better in diffused and partial light conditions. However, the growth waspoor in water - stressed soils. The aqueous extracts from shoots, rainleachates, litter and root exudation significantly reduced the germination andseedling growth of pearl millet, wheat and corn. Shoot extract retarded thedevelopment of meristematic cells of test species. It was concluded that A.viridis germinates easily, grows better in diffused light with normal moisturecondition and it possess allelopathic potential against crops.
