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.

The experiment was conducted in a completely randomized design with a split-plot arrangement and four replications. Industrial seed treatment technologies were assigned to the main plots, while storage periods (0 and 50 days) were allocated to the subplots. Seed physiological quality was assessed using the standard germination test, first germination count, accelerated aging test, seedling emergence in a sand substrate, seedling length, and seedling dry biomass. The results indicated that the inclusion of the biostimulant fertilizer improved physiological performance compared with treatments without fertilizer, with the formulation composed of thiophanate-methyl + fluazinam associated with bifenthrin + imidacloprid combined with fertilizer (Composition III + Fertilizer) showing the most consistent performance across the evaluated variables. Storage for 50 days reduced seed vigor and germination, particularly in untreated seeds. Among the evaluated technologies, only Composition II + Fertilizer, Composition III, and Composition IV + Fertilizer maintained commercial seed quality after storage. These findings demonstrate that integrating a biostimulant fertilizer into industrial seed treatment protocols enhances seed physiological performance and mitigates storage-related deterioration, representing a technically viable strategy to preserve soybean seed quality during commercialization and short-term storage.</p> Melissa Cassou Trindade Nunes Helen Mariana Cock Protzek Diego Vaz Gutoski Isabella Trevisan Schneider Alessandro Lucca Braccini Copyright (c) 2026 2026-03-06 2026-03-06 11 1 22 31 10.55284/cjac.v11i1.1763
