The experiment was carried out in Diyala Governorate, Khalis District, for the agricultural season 2021–2022 to study the effect of spraying with zinc, calcium, and sorbitol alcohol on qualitative yield traits of the potato cultivar of Arizona. The treatments of spraying zinc, calcium, and sorbitol individually on potato plants significantly increased all studied traits, such as the percentage of protein, dry matter, starch, total sugars, and total soluble solids (TSS%). The treatments of sorbitol (10 g. L-1 ) + Zn (200 mg. L-1 ) + Ca (1 g. L-1 ) gave the highest percentage of protein in the tubers, reaching 11.56% compared to the control treatment of 8.106%, the treatments of sorbitol (10 g. L-1 ) + Zn (0 mg. L-1 ) + Ca (0.5 g. L-1 ) gave the highest percentage of dry matter in the tubers, reaching 18.69% compared to the control treatment of 11.88%, the treatments of sorbitol (10 g. L-1 ) + Zn (0 mg. L-1 ) + Ca (0.5 g. L-1 ) gave the highest percentage of starch in the tubers, reaching 12.66% compared to the control treatment of 6.61%, the treatments of the sorbitol (10 g. L-1 ) + Zn (100 mg. L-1 ) + Ca (0 g. L-1 ) gave the highest percentage of total soluble solids, reaching 6.203%. In contrast, the control treatment gave the lowest value, reaching 3.4130%; the treatments of sorbitol (10 g. L-1 ) + Zn (0 mg. L-1 ) + Ca (1 g. L-1 ) gave the highest percentage of total sugars, reaching 3.547%, compared to the control treatment of 2.231%. Keywords. Potato, zinc, calcium, sorbitol alcohol
