Abstract
Phytochemicals are secondary metabolites produced by a variety of plants that can prevent competitor species from germinating. Allelopathy is the name for this process, mediated by various substances, the most common of which are phenolic compounds. Plant allelochemicals can thus be employed in agricultural systems to suppress weeds and crops. This study aimed to determine how Melia azedarach (L.) aqueous leaf extracts affected Sesamum indicum (L.) and Abelmoschus esculentus (L.) seedlings in terms of germination, seed index, seedling length, and biochemicals of crops. Aqueous extract of Melia azedarach L. leaves was assayed at 10%, 20%, 40%, 60 %, and 80% concentration on germination and initial growth of sesame and okra in pot culture. However, the results of a pot experiment with test crops revealed that leaf extract had stimulatory and inhibitory phytotoxic effects on germination, seedling growth, and biochemicals compared to control. Depending on the plant species and extract content, the efficiency of these inhibitory actions differed.
