The ability of one plant to compete with another is related to factors such as species, population, emergence time and morpho physiological characteristics .Soybean can be seen as a weed when it voluntarily appears in places from grains lost in the harvest, becoming a plant of competitive potential, which can cause losses. Having proposed it, the objective of this study was to evaluate the relative competitive ability of common bean cultivars with raccoon soybean by means of a substitute series arrangement. The experiment was conducted in an open place on the rural property of Mr. Ademir Julio in the municipality of Nova Esperança do Sudoeste -Paraná, in 2018. The experiment was carried out in a substitute series to test the competition of "raccoon" soy bean cv. TMG 7062 and cv. Bean (BRS Estilo e IPR Uirapuru) in five different population proportions (0%-100%, 25%-75%, 50%-50%, 75%-25%, 100%-0%), forbeans–soybean, respectively. Plastic vessels with a capacity of ten liters were used for the test in DIC. A previous germination test was performed using trays with sand to determine uniform germination. The variables studied were plant height (cm), leaf number and shoot dry mass (MSPA). The variables were submitted to the method of graphic analysis of relative productivity , through the construction of a diagram based on relative productivity (PR) and total relative productivity (PRT) in the different proportions of plants of the crop and weed, and subsequently calculated the indices relative competitiveness (CR),relative grouping coefficient (K) and aggressiveness (A), and submitted to dunnett test (α=0.05) for comparison of means. From the results, it was verified that the rew as competition between the crop and the weed, generating more significant losses for dry mass, and in as maller proportion for height and number of leaves, for both bean cul-tivars evaluated. Further more, the presence of intraspecific competition was observed instead of interspecific competition. It was noticed that the carioca beans ...
