      abstract = {This study investigated Chromolaena odorata's allelopathic influence on Citrillus lanatus and Cucumis sativus seedling emergence and growth. We used a completely randomized design with three treatments (T1: 5g, T2: 10g, T3: 15g) in 300g of soil, each with four replicates. We assessed seedling emergence percentage (SE%), seedling emergence index (SEI), time spread of emergence (TSE), allelopathic response index (ARI), seedling lengths (SL), and dry weights (DW), analyzing data with ANOVA and Tukey's HSD test. C. lanatus SE% (97.5%, 97.5%, 92.5%, 72.5%) and SEI (15.9, 14.9, 13.6, 10.9) were not significantly reduced. SE% (90%, 50%, 55%, 30%) and SEI (13.2, 9.5, 5.5, 2.3) of C. sativus decreased non-significantly. TSE values in the treatment plots were all higher than the control while ARI values were negative indicating delayed and inhibited emergence in both crops. Contrary to the inhibitory effect of T1, T2 and T3 on SL of C. sativus, T1 and T2 stimulated SL in C. lanatus while T3 inhibited growth. DWs did not reduce significantly but was concentration-dependent. This study underscores the variable allelopathic effects that C. odorata possesses which is influenced by plant species, allelopathic material concentration, and crop growth phase. Consequently, C. odorata can be strategically incorporated into crop rotation and weed control practices.},
