Micronutrient deficiencies (hidden hunger), particularly in iron (Fe) and zinc (Zn), remain one of the most serious public health challenges, affecting more than three billion people globally. A number strategies are used to ameliorate problem micronutrient improve nutritional profile food products. These include (i) dietary diversification, (ii) industrial fortification supplements, (iii) agronomic approaches including soil mineral fertilisation, bioinoculants crop rotations, (iv) biofortification through implementation biotechnology gene editing plant breeding. efforts must consider patterns culinary preferences consumer stakeholder acceptance new biofortified varieties. Deficiencies Zn Fe often linked poor status agricultural soils, resulting low amounts and/or availability these nutrients staple crops such as common bean. This review describes genes processes associated with accumulation bean, a significant source Africa that plays an important role security. We discuss conventional breeding, transgenic being deployed beans. also requirements successful bean programmes, highlighting gaps current knowledge, possible solutions future perspectives.

Abstract Iron (Fe) is necessary for plant growth and development. deficiency disrupts major metabolic cellular activities such as respiration, DNA synthesis, chlorophyll synthesis. also activates various pathways vital to numerous enzymes. widely distributed in soil, but plants do not readily absorb it. In addition neutral pH, Fe forms insoluble complexes under alkaline conditions. The fundamental cause of chlorosis an imbalance between the solubility soil demand by plants. Various fertilizers, including organic, chelated, inorganic, are administered leaves treat chlorosis. Currently, used fertilizers expensive, easily adsorb on particles, leach out with water, thereby diminishing their efficiency. They need be applied repeatedly, resulting excessive fertilizer concentration that can harm usage nanofertilizers agricultural production has expanded address disadvantages existing fertilizers. advantages nanosized include physical chemical characteristics, high surface area volume ratio aids easy absorption plants’ roots leaves. Controlled‐release iron oxide supply regulated release nutrients a way coordinated nutritional needs crops. This improves accumulation plant, filling gap nutrient lowering environmental risks due leaching. possibility nanoparticles micronutrient uptake mechanism action, advantages, limitations critically highlighted this review article.

Iron (Fe) oxide nanoparticles (NPs) improve crop growth. However, the comparative effect of root and foliar-applied different sources Fe NPs on plant performance at morphological physiological levels still needs to be discovered. In this study, we characterized growth responses hydroponic-cultured maize seedlings four (i.e., α-Fe2O3, γ-Fe2O3, Fe3O4 NPs, bulk Fe3O4) two application methods (root vs. foliar). Results showed that concentration in shoot increased by elevating level from 100 mg L-1 500 L-1. Overall, were as follows: > γ-Fe2O3 α-Fe2O3 Fe3O4. The concentrations ranging had no significant effects various parameters maize, including biomass, chlorophyll content, length. biomass 23-37% application, whereas it was 5-9% foliar application.
