Individual malnutrition is a worldwide problem that mostly affects people whose diets (often of plant origin) are deficient in essential vitamins and minerals. Low levels of micronutrients in plants are associated to declining soil concentrations and/or low bioavailability, as well as the presence of abiotic stressors that disrupt plant growth and development. Agronomic biofortification of crops is a promising technique to increase the concentration of micronutrients in edible sections of crops without sacrificing production, and it is often regarded as the most cost-effective strategy for addressing hidden hunger around the world. The focus of the study is on the elements that influence the efficacy of biofortified crops (a type of application, form, and a dose of applied microelement, biofertilizers, and nano fertilizers). The accumulation of zinc, and iron in edible sections of plants, their impacts on metabolism, morphological, and yield parameters, and their impact on plants' defense mechanisms against abiotic stress such as salt, high/low temperature, heavy metals, and drought were also studied. Finally, future agronomic biofortification research directions are suggested.
