The aimed of this study was to evaluate the physical and physiological characteristics of the Pearl beans under different irrigation levels in Oeste Paulista region. The experiment was conducted in the city of Pirapozinho, Sao Paulo, using pots of 25 x 32 cm, under field conditions, from March to May. The experimental design was a randomized block with six depths of irrigation: 25%, 50 %, 75 %, 100 % , 125 % and 150 % crop evapotranspiration ( ETc ) and 5 replication. The parameters evaluated were plant height, shoot dry weight , root dry weight, number of pods per plant, pod weight, number of seeds per pod, seed germination and foliar proline. The data were analyzed using the F test and then the Tukey test for comparison of the probability level of 5 %. It was observed that the results were significant for the weight of the strings, the number of seeds per pod and the concentration of proline. It was concluded that the depth of irrigation of 75 % ETc resulted in higher seed production. The irrigation of 25 % ETc promoted water deficit, indicated by the higher concentration of proline in fresh leaves.
