The yield response of several sweet potato varieties to salinity stress has been extensively studied in the scientific literature, but no research on the Koganesengan and Beniazuma varieties has been identified. The purpose of this study was to examine the effects of various irrigation salinity levels on the growth (vine and tuber lengths, stem and tuber diameters, and number of leaves, shoots, and tubers), yield (fresh, dry, tuber, and total yields, and water use efficiencies for vine, tuber, and total yields), and quality parameters (dry matter, ash, crude fiber, starch, phenolic matter, antioxidant activity, ß-carotene, ascorbic acid, protein, saccharose, glucose, and fructose contents) of these sweet potato varieties under drip irrigation. The findings show that without a varietal difference, increasing water salinity levels increased soil salinity and decreased soil pH values. Some growth and yield parameters of “Beniazuma” were negatively affected by the salinity level, but not those of “Koganesengan”. Irrigation salinity levels only had an effect on the crude fiber content and antioxidant activity of “Koganesengan” and the ash, starch, ß-carotene, and ascorbic acid contents of “Beniazuma”. Significant variations between varieties were only seen under the control treatment for all yield parameters (except dry vine yield) and water use efficiency values. According to the calculated salinity threshold and slope values, “Beniazuma” is more sensitive to salt stress than “Koganesengan”.
