Under salt stress, plant growth and development are negatively affected due to physiological changes,requiring strategies such as fertilization management minimize these effects. In this scenario, study aimedto evaluate the effect of combinations nitrogen, phosphorus, potassium on growth, leaf waterstatus, electrolyte leakage, gas exchange West Indian Cherry grown under water stress in secondyear production. The experiment was conducted a protected environment Campina Grande - PB.The treatments were distributed randomized block design with 2 × 10 factorial arrangement threereplications corresponding two electrical conductivity levels irrigation water– ECw (0.6 4.0 dS m-1)and ten (80-100-100; 100-100-100; 120-100-100; 140-100-100; 100-80-100; 100-120-100; 100-140-100; 100-100-80; 100-100-120, 100-100-140% therecommendation second year production).
