Globally, micronutrient malnutrition alone affecting more than two billion people, mostly among resource-poor families in developing countries, with Zn, Fe, I and vitamin A deficiencies most prevalent. Approximately, five million children dies micronutrient malnutrition every year. Currently, micronutrient malnutrition is considered to be the most serious threat and global challenge to human kind and it is avoidable. Among different micronutrients, zinc and iron deficiency is a well-documented problem in food crops due to which crop yields and nutritional quality decreases. Generally, the regions in the world with Zn-deficient soils are also characterized by widespread Zn deficiency in humans. Current trend indicate that nearly half of world population suffers from Zn and Fe deficiency. | Agronomic biofortification of paddy through nitrogen zinc and iron fertilization A review
