West Indian cherry stands out in the Brazilian fruit scenario due to the nutritional quality of its fruits, making it a promising crop in the generation of employment and income. However, the occurrence of water sources with high concentrations of salts is a limiting factor for the expansion of crop area. In this context, the objective was to evaluate the production and post-harvest quality of West Indian cherry cv. BRS 366 Jaburu under prolonged saline stress and potassium-phosphorus fertilization combinations in the second year of cultivation. The experiment was carried out in 250 L lysimeters in a greenhouse in the municipality of Campina Grande-PB, Brazil. Treatments were distributed in randomized blocks in a 5 x 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.6, 1.4, 2.2, 3.0, and 3.8 dS m-1) and four combinations of potassium- phosphorus fertilization (100/100, 85/85, 60/60, and 45/45% of K2O/P2O5 recommendation for the second year of cultivation) with three replicates. Irrigation water salinity of up to 3.8 dS m-1 does not compromise the post-harvest quality of West Indian cherry. The increase in water salinity reduces mean fruit weight and water consumption of plants, while waters with electrical conductivities of 3.0 and 2.0 dS m-1 promote the maximum values of total soluble solids and ascorbic acid in the fruits, respectively. The supply of 45/45% K2O/P2O5 of the fertilization recommendation provides the higher content of ascorbic acid in West Indian cherry fruits and, when associated with ECw of 1.4 dS m-1, promotes the higher production of the crop.
