The present work was carried out in order to verify the influence of different plant densities (133.3 to 533.3 thousand plants.ha-1), different row spacings (0.30 m, 0.45 m and 0.60 m) and number of plants per row (8, 12 and 16), in the yield components and in the crop growth of Phaseolus vulgaris L., cultivars IAC-Carioca Pyatã and IAC-Bico de Ouro. The experiment was conducted in a Latossol soil, under irrigation during the winter of May-August of 1995, in Selvíria, State of Mato Grosso do Sul, Brazil. A decrease was observed in the number of pods and number of grains per plant with the increase in the plant density or with the decrease in row spacing. Under row spacing decrease, there was an increase in the grain yield and seed mass, due to the larger number of plants ( larger plant population). Two of the cultivars showed larger grain yield under the plant density of 266.7 thousand plants.ha-1, and 0.30 m spacing and 8 plants per meter.
