The presence of allelochemicals in the soil affects the growth, survival, and reproduction of neighbouring plants. This phenomenon influences crop yield and the dynamics of weed-crop interactions. This study was conducted with the aim of comparing the allelopathic effects of four plant species collected from Nigeria Police Academy, Wudil against the growth of beans (Phaseolus vulgaris l.). Results revealed that, comparing the concentrations of the extracts used, 20 mg/l had the greatest effect on the research materials. Euphorbia hirta was observed to create the highest inhibition on shoot and root lengths (25.98 and 38.49 %) respectively. Similarly, Tridax procumbens produced the highest inhibition on germination percentage (17.19 %) while, Cynodon dactylon and Euphorbia hirta had the highest inhibiton on seedling vigour (20.03 and 19.78 %) respectively. Based on the results obtained from this study, it can be concluded that all the tested weeds had an effect on the growth of beans. The greatest inhibitory effect was observed when the extracts of E. hirta was used. It was also observed that 20 mg/l of the extracts had the highest effect.
