Stunting affects 41 % of children aged under 5 years. Zn is one of the key micronutrients that is associated with stunting. Zinc (Zn) is an essential trace element in the human diet, playing a critical role in numerous physiological processes, including immune defense against infectious diseases. Notably, the global distribution of dietary Zn deficiency closely mirrors regions of soil Zn deficiency. In South Asia, Zn malnutrition is particularly prevalent due to the heavy reliance on rice, a staple crop with inherently low Zn content. Among different interventions to combat Zn deficiency include dietary diversification, food fortification, supplementation, and biofortification Zn biofortification of rice stands out as the most cost-effective and sustainable strategy for the region. While conventional breeding and transgenic approaches have successfully enhanced Zn levels in cereals, their effectiveness diminishes in Zn-deficient soils. This review therefore emphasizes agronomic biofortification strategies specifically the timing, dosage, and method of Zn fertilizer application and examines how nitrogen and phosphorus management, along with crop establishment practices, influence Zn accumulation in rice. We further propose data-driven Zn recommendations to optimize crop responses to fertilization and advocate for targeted policies that support agronomic biofortification in regions where Zn fertilizer responsiveness is high.</p> Humayun Kobir Md.
