Abstract :

 The allelopathic effect of various concentrations of aqueous extracts of Neem (Azadirachta indica A. Juss.) leaves on Vigna unguiculata L., Vigna mungo (L.) Hepper, Vigna aconitifolia (Jacq.) Maréchal, and Cicer arietinum L. was conducted in sterile petri dishes at standard growth conditions. The results depicted that the aqueous leaf extract of Azadirachta indica significantly inhibited the seed germination, shoot length and root length. The inhibition of growth parameters were increased with the increased concentration of extract. The investigations also revealed that at 75% and 100% there was more inhibition in all test plants whereas at 50% concentration growth was enhanced in Vigna aconitifolia and Vigna unguiculata.
