Foliar application of leaf extracts of neem (Azadirachta indica L.) and kalmegh (Andrographis paniculata L. (50g/500ml each) on 30 days old plants of horse gram (Dolichos biflorus L. cv. BR 5) and grass pea (Lathyrus sativus L. cv. BIOL 212) under field conditions resulted in significant increase of the potential status of plants. The levels of chlorophyll, protein, insoluble carbohydrate, DNA and activity of catalase enzyme in leaves of seedlings were found to be higher in the treated plant samples. On the other hand, soluble carbohydrate contents were found to be lower in treated samples than control ones. The promising effects of the plant extracts on plant potentiation of horse gram and grass pea are apparent in this investigation.
