The aim of this study was evaluate the agronomic p erformance of common bean cultivars ac- cording to phosphate fertilizing in the south of To cantins State. The experimental design was randomiz ed blocks with four replications. The treatments were constituted by 19 common bean cultivars submitted t o low and high levels of phosphorus in the soil (20 and 1 20 kg ha -1 of P 2 O 5 at planting, respectively). The increase of phosphorus promoted an addition in average of plant height, height of insertion of the first pod, stem diameter, number of pods per plant, number of grains per pod, number of grains per plant, weight of hundreds gra in and grains yield an cultivars IAC-Centauro, IAC-Galante , IPR-Juriti and IPR-Eldorado . The cultivars IAC-U na and IPR-Siriri present higher grains yield when sub mitted to the application of 120 kg ha -1 of P 2 O 5 .
