Özet
Theyield response of several sweet potato varieties to salinitystress has been extensively studied in the scientific literature,but no research on the Koganesengan and Beniazuma varieties has beenidentified. The purpose of this study was to examine the effects ofvarious 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 efficienciesfor 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 findingsshow that without a varietal difference, increasing water salinitylevels increased soil salinity and decreased soil pH values. Somegrowth and yield parameters of Beniazuma were negativelyaffected by the salinity level, but not those of Koganesengan.Irrigation salinity levels only had an effect on the crude fiber contentand antioxidant activity of Koganesengan and the ash,starch, ss-carotene, and ascorbic acid contents of Beniazuma.Significant variations between varieties were only seen under thecontrol treatment for all yield parameters (except dry vine yield)and water use efficiency values. According to the calculated salinitythreshold and slope values, Beniazuma is more sensitiveto salt stress than Koganesengan.
