The experiments were conducted at Chaudhary Sarwan Kumar Krishi Vishavidhyalaya,Palampur, Himachal Pradesh, India to see the allelopathic effect of medicinal leaf extracts of Ocimum sanctum L., Calotropis procera(Ait.) Ait.f and Astragalus tribuloides Delile on the plumule length of mungbean (Vigna radiata L. Wilczek) in vivo 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 plumule length of mungbean in vivo conditions. All the extracts of Ocimum sanctum L.showed no effect in comparison of control. The alcoholic extract of Calotropis procera(Ait.) Ait.f, produce considerably higher as compared to control followed by aqueous, acidic but alkaline extract showed negative effect on plumule length of mungbean. However, the alcoholic and alkaline extracts of Astragalus tribuloides Delile showed positive effect than aqueous acidic extract on the plumule of mungbean. http://www.agriculturejournal.org/volume4number1/allelopathic-effect-of-extracts-of-medicinal-plants-on-mung-bean-in-vivo-conditions/ Extracts of Medicinal Plants; Plumule Length; Vivo Condition
