Agronomic Zn Biofortification of Cereal Crops a Sustainable Way to Ensuring Nutritional Security: A Review

Nutritional deficits in humans and animals constitute a hidden epidemic many impoverished areas across the world. The staple foods of developing South Asian African nations, such as rice, wheat, maize, are poor micronutrients. In recent past, lack food diversification i.e., cereal-based crops low minerals, is another danger to nutritional quality security. Because inherently low-level accumulation nutrients cereal crops, they primary target for bio-fortification among all crops. Among different micronutrients, zinc (Zn) an important micronutrient that plays vital role variety physiological functions, its scarcity will result lower crop yields productivity. Agronomic practices like application fertilizers soil, nutri-priming, foliar spray etc. enhance availability uptake Zn As result, growth development, parameters yield attributes enhanced significantly. Therefore, agronomic biofortification utmost achieve Furthermore, boosted productivity alleviate hunger, addition aspects, proving be sustainable cost-effective strategy. With soil fertiliser applications, including amendments, interventions boost concentration this review importance procedure improve agricultural solution solve security challenges discussed.
