Zinc (Zn) is a micronutrient, which is involved in activating many physiological and biochemical processes. Inadequate supply of Zn affects crop growth, development and in turn yields. Most of us depend on agriculture based foods which are grown under inadequate Zn supply and hence we get less of Zn as recommended. A few strategic approaches are being adapted to overcome inadequacy of Zn in food. Biofortification is one of the best strategies to enhance the Zn content in the food grain. Among these, direct fertilizer application to the plant is the easiest way to enhance the Zn content in the food grain. Perhaps, excess use of Zn is not recommended because of heavy metal and di cationic characteristic properties. In this context application of the nano fertilizer enhances efficacy of targeted delivery and nutrient use efficiency. | ZnO nanoparticle improves maize growth yield and seed zinc under high soil pH condition
