  Background and Objective: Potassium plays a very important role in plant physiology and plays a significant role in plant resistance to biotic and abiotic stresses. The objective of this study was to compare the effect of using different sources of potassium fertilizers as foliar spray on the production and quality of early sweet grapes cv. under salinity stress. Materials and Methods: This study was carried out during two successive seasons (2019 and 2020) in a private vineyard orchard at west Samalout, Minia Governorate by choosing of 21 vines seven treatments each treatment replicated 3 replicates The chosen vines were 7 years old, grown in a sandy soil, planted 2×3 m, irrigated with drip irrigation system, all of the vines took the same fertilization treatment except the foliar application of potassium fertilizers. Results: Using of (K-MCT) was very effective in enhancing the vegetative growth characters like main shoot length, no of leaves per shoot, cane thickness, leaf area, total chlorophylls, the nutritional statute of leaves (N, P, K, Mg) and all of examined fruiting characters compare to control (untreated vines) and better than using of both of potassium sulphate and potassium Thio-sulphate at its two concentrates. The spraying of (K-MCT) at 500 ppm was significant to use it at 200 ppm. The using of (KTS) at 500 then at 200 ppm respectively gave results better than (K2SO4) but lower than (K-MCT) at their two concentrates. When using of two concentrates of (K2SO4) wasn’t significant. Conclusion: Using of (K-MCT) at 500 ppm was the superior treatment in all of the parameters which has been examined like vegetative growth characteristics (pigments and nutrient contents of leaves), fruit characterizes and yield.
