Abstract: Common bean new cultivars recommendation for farmers should always be accompanied by specific recommendations for plant populations and fertilizer doses. Then, this study was conducted during the summer season, at Ponta Grossa country, Parana State, Brazil. The objective was to investigate the effect of plant populations and nitrogen rates on growth and yield of the cv. IPR Tangara culivar, recently recommended for Paraná State. The statistical design was a randomized block with four replications and 4 x 4 factorial scheme involving four populations (100, 200, 300 and 400 thousand plants ha-1) and four N rates (0, 40, 80 and 120 kg ha-1 N) source urea, applied half at sowing and half-dressed. Were evaluated the final stand, plant height and grain yield with its primary components (pods number per plant, seeds number per pod and the one hundred grains weight). In these soil, the N increase up to 74 kg ha-1increases the yield. The population increase, in the 90-250 thousand plants ha-1range reduces the pods number per plant, but does not affect grain yield. The IPR Tangara cultivar has good agronomic performance and good yield and can be used byfarmers in Parana State.
