In potatoes, Zinc deficiency symptoms are variable. In general, the Leaves are smaller and the plants are stunted in growth. The leaves fold inwards giving a fern-like appearance, grayish brown to bronze-colored Blotches appear first on the middle leaves and latest on all leaves. Yield responses to zinc can be expected in crops grown on soils with a low or high pH if the Zinc levels are low. Therefore, Zinc has an important role in potato production. Zinc maintains the active state of auxin and lack of it leads to excessive destruction of auxin due to an increase in oxidation. Zinc is also essential for the function and structure of aldolases, dehydrogenases, phosphatases, aspartate transcarbamylase, and isomerase.
