Abstract:

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. Cereal crops mainly rice which play an important role in satisfying daily calorie intake in developing world, but they are inherently very low in Zn and Fe concentrations in grain. It provides 21% of energy and 15% of protein requirements but does not provide essential micronutrients i.e. Zn and Fe to eliminate their deficiencies. So, the enrichment of rice with N, Zn and Fe fertilization can solve the problem of Zn and Fe deficiencies, which are two amongst the most serious nutritional problems affecting human beings. Among the strategies being discussed as major solution to Zn and Fe deficiency with the use different modes of fertilizers, agronomic biofortification appears to be a most sustainable and cost-effective approach useful in improving Zn and Fe concentrations in grain. Scientific evidences show this is technically feasible without compromising agronomic productivity.
