One of the main factors responsible for decreases in agricultural production products, which affect food production, are weeds. Currently, the usual means of management for these invasive plants is the use of chemical control. However, the search for more sustainable ways to contribute to the alternative management of these environments is constantly being studied, with emphasis on the study of allelopathy, which can contribute significantly as one of the promising forms of ecological management of weeds in agroecosystems. Therefore, the objective of the research was to evaluate the allelopathic potential of cowpea (Vigna unguiculata L.) and green mung bean (Vigna radiata L.) in the germination and initial development of the cucumber culture. For the elaboration the experiment in the laboratory, a completely randomized design in a 2x4 factorial scheme was used. The factors were constituted by two species of beans and four concentrations of the extract of the seeds (0%, 7.5%, 15%, 30%), being the treatments formed by the combination of the studied factors, constituted by 4 repetitions for each treatment. Allelopathic potential was observed for all studied species, with cowpea extract being the most harmful for all analyzed variables, consisting of the most promising in studies on ecological management.
