This study investigates the allelopathic effects of root exudate extracts from Chromolaena odorata on germination and growth six crop species. The results reveal variable sensitivity among species, with control treatment consistently exhibiting superior percentages. Initially, some including Abelmoschus esculentus (okra), Solanum lycopersicum (tomato), Cicer arietinum (chickpea), experienced a substantial decline in germination, indicating potential inhibitory effect exudates, although partial recovery was observed subsequent treatments. Phaseolus vulgaris (common bean) displayed moderate decrease, while Zea mays (corn) exhibited most significant drop rates, albeit slight at higher concentrations exudates. Conversely, Cucumis sativus (cucumber) appeared least affected by Moreover, all species demonstrated reductions shoot lengths increasing Chlorophyll content analysis revealed reduction across treatments, highlighting concerns regarding photosynthetic efficiency overall plant health. species-specific response to exudates suggests varying metabolic or adaptive mechanisms crops. Additionally, malondialdehyde (MDA) levels, indicative oxidative stress, varied A. P. showing dose-dependent increase, S. peak intermediate levels. Z. marginal elevation MDA content, potentially presence protective compounds within C. showed steady increase MDA, suggesting limited mitigation effects. These findings feature complexity interactions highlight need for further research into active their modes action develop sustainable weed management strategies safeguarding Understanding these dynamics is crucial maximizing benefits allelopathy agriculture.
