Zinc is micronutrient essential for normal growth and development of plants. It is required for the functioning of many different enzymes and proteins involved in various metabolic pathways in plants for instance, in photosynthesis and carbohydrate metabolism, protein as well as auxin metabolism, the maintenance of membrane integrity, pollen formation and resistance to pathogen attack. Zinc deficiency in food crops cause decreased crop yields and nutritional quality. Generally, the regions in the world with Zn-deficient soils are also characterized by widespread Zn deficiency in humans. Zinc deficiency is attributed by large zinc removals due to high crop yields and intensive cropping systems, lesser application of organic manures, increased use of phosphatic fertilizers resulting in P-induced zinc deficiency. Zinc deficiency in crop production can be managed through agronomy and genetic improvement. Fertilization could correct zinc deficiency and ensure optimum yields and increased zinc concentration in grain. Indiscriminate fertilizer use has polluted the soil and water hence the use of biofertilizers (Zn solubilizing bacteria) along with integrated nutrient management is sustainable approach for managing zinc deficiency.
