Abstract: Allelopathy is a type of interaction in which plants release allelochemicals that can have detrimental effects on the growth and development of neighboring plants.Melia dubia Cav., ashort rotation tree species, with rapid growth that has a number of commercial and therapeutic purposes, is becoming more common in agroforestry systems. Hence, the current study is undertaken to investigate the effect of leaf extracts of Melia dubia Cav. on field crops such as Arachis hypogaea L., Cicer arietinum L., Vigna radiate L., and Zea mays L.Bioassay was conducted to test the allelopathic effects of aqueous leaf extracts on seed germination, growth, and biomass and relative allelopathic effect was calculated according to the standards. In this study aqueous extracts were prepared at varied concentrations [25%, 50%, 75%.100% and Control (0)] (in w/v) and were tested on the aforesaid agricultural crops. The bioassay findings revealed that the germination percentage, shoot androot development of the tested crops significantly decreased as the concentration of the extracts increased.
