Abstract:- Weeds are undesirable plant growing in an area where they are not wanted. These plants are generally highly competitive and adaptable to very wide environmental conditions. While competing with crop plants for light, nutrients and moisture contents of the soil, many weeds have allelopathic effects on crop plants. Effect of ten weeds leaf extract at different concentration such as 5, 10, 15 and 20% were tested on seed germination and seedling development of Vigna aconitifolia (Jacq). The distilled water was used as a control. The Portulaca oleracea L., Euphorbia hirta L., Lagerra decurren showed stimulatory effect as concentration increases. Tribulus terrestris L. has shown inhibitory effect while Sphagneticola trilobata L., Oxalis corniculata L., Strobilanthes callosus, Gomphrena serrate L., Ageratum conyzoides L., Phyllanthus amarus L. have moderate inhibitory effect on seed germination, root length, shoot length and seedling growth of Vigna aconitifolia L. This indicates that allelochemical present in aqueous extract of ten different weeds have shown inhibitory or stimulatory effect on plant growth.
