Indian soils at an average of 50% are Zinc deficient which limits the adequate Zinc levels of 20-100 mg/kg leaf (on dry weight basis). Zinc requirement in different crops varies greatly but it is one of the most essential micronutrients that promotes Nitrogen metabolism and imparts syntheses of carotene, protein, amino acids and starch, boosts chloroplast, produces enzymes and plant cells, increases chlorophyll content, reduces several diseases like khaira disease in paddy, mottled and bronzing leaf of citrus, little leaf of cotton, white bud of maize and zinc deficiency disorders, protects crops against extreme hits and colds, increases uptake of soil nutrients, increases growth and enhances flower, fruit, grain, cane, tuber, straw and fodder yields.
