This work was accomplished with the objective of evaluating the effect of different levels of salinity of the irrigation water in the development of cowpea. The used design was it entirely randomized with five treatments (0.5, 2.13, 2.94, 3.5 and 5.0 dS m-1) and three replications. The plants were collected to the 45 days after sowing, being appraised: the diameter of the stem, number of nodules in the roots, height, number of leaves, leaf area and total matter dries. The salinity influenced lineally in the vegetative growth of the bean cowpea, being all the reduced characteristics with of the saline level. The most affected characteristics for the largest saline level were leave area (65.90%), the matter dries (69.10%) and the number of nodules (98.71%).
