The allelopathic effect of medicinal leaf extracts of Ocimum sanctum L., Calotropis procera(Ait.) Ait.f and Astragalus tribuloides Delile on the radical length of mungbean (Vigna radiata L. Wilczek) in Vitro conditions. The results indicated that different extracts such as alcoholic, aqueous acidic and alkaline extract of Ocimum sanctum L., Calotropis procera(Ait.) Ait.f and Astragalus tribuloides Delile showed different radical length of mungbean in Vitro conditions. Alcoholic extract of Ocimum sanctum L. showed highest radical effect in comparison of other extracts. The aqueous acidic extract of Calotropis procera(Ait.) Ait.f, produce considerably higher as compared to control followed by alcoholic but alkaline extract showed negative effect on radical length of mungbean. However, the alcoholic extracts of Astragalus tribuloides Delile showed positive effect than aqueous acidic extract and alkaline on the radical length of mungbean.
