AbstractAlthough zinc is considered as micronutrient it has a vital role in plant growth. Among all metals, the largest number of proteins required zinc for their catalytic function. Zinc-binding proteins make up nearly 10% of all protein in biological systems. Zinc plays a vital role in biological systems like structural integrity of membrane and contribution to protein synthesis also gene expression. According to FAO that zinc is considered as most commonly deficient in agriculture soils about 50%. Sometimes add more phosphorus may lead to the deficient of zinc in the soil for some reason. In plants zinc deficient can be noticed by the leaf chlorosis, necrotic spots on leaves, bronzing of leaves, resetting of leaves, stunting of plants, dwarf leaves, malformed leaves. Zinc deficient soil can as treat well in many ways and the most used method is the application of zinc-containing fertilizers. Zinc sulphate is a widely used fertilizer. If soils are untreated it may cause up to 40% yield loss without the appearance of distinct leaf symptoms. One percent zinc-containing NPK and urea fertilizer are available in many countries. Zinc also is used as seed treatment instead of the application of fertilizer and root dipping or transplant seedlings. Thus, zinc is considered an important micronutrient for plant growth.
