“…As plants need more amount of macronutrients especially NPK for their growth and production, it is assumed that global utilization of composite NPK fertilizer will increase up to 263 million ton by 2050 [ 48 ]. Though this employment of NPK fertilizers will largely contribute to per-capita wheat production, it will also serve as a source of soil and water pollution [ 49 ]. In this scenario, the enhanced use of macronutrient NFs in wheat production can be a more environment-friendly and sustainable approach.…”

“…Wheat nanobiofortification should be employed in the light of recommended daily allowance of nutrients for human that is 1000 mg Ca, 3000–4000 mg K, 700 mg P, 200 mg, 1500 mg Na, 2.3 mg Mn, 1.2 mg Cu, 1–3 mg Fe, and 36–150 µg Zn [ 5 , 100 ]. The natural properties of different nanomaterials such as their required dosage concentrations, material types, coatings, solubility, size, shape, and surface area can contribute to the severe health risks to human beings [ 49 ]. The chemical and physical strategies for NPs synthesis can have greater toxicity as compared to the biogenic synthesis of nanoparticles.…”

“…Additionally, due to their smaller size, NPs can be easily absorbed by plants and enter in food chain increasing the risks of health hazards. Thus, scientists, growers, and consumers should be carefully educated about the do’s and don’ts of nanofertilized wheat crops and NPs should be used for wheat biofortification under the regulatory framework [ 49 ].…”

The deficiency of nutrients in food crops is a major issue affecting the health of human beings, mainly in underdeveloped areas. Despite the development in the methods of food fortification, several barriers such as lack of proper regulations and smaller public-private partnerships hinder its successful implementation in society. Consequently, genetic and agronomic biofortification has been suggested as the potential techniques for fortifying the nutrients in diets. However, the time-consuming nature and restricted available diversity in the targeted crop gene pool limit the benefits of genetic biofortification. In agronomic biofortification, organic fertilizers face the problem of prolonged duration of nutrients release and lesser content of minerals; while in inorganic fertilizers, the large-sized fertilizers (greater than 100 nm) suffer from volatilization and leaching losses. The application of nanotechnology in agriculture holds enormous potential to cope with these challenges. The utility of nanomaterials for wheat biofortification gains its importance by supplying the appropriate dose of fertilizer at the appropriate time diminishing the environmental concerns and smoothening the process of nutrient uptake and absorption. Wheat is a major crop whose nano-biofortification can largely handle the issue of malnutrition and nutrients deficiency in human beings. Though several research experiments have been conducted at small levels to see the effects of nano-biofortification on wheat plants, a review article providing an overview of such studies and summarizing the benefits and outcomes of wheat nano-biofortification is still lacking. Although a number of review articles are available on the role of nanotechnology in wheat crop, these are mostly focused on the role of nanoparticles in alleviating biotic and abiotic stress conditions in wheat. None of them focused on the prospects of nanotechnology for wheat biofortification. Hence, in this review for the first time, the current advancement in the employment of different nanotechnology-based approaches for wheat biofortification has been outlined. Different strategies including the supply of nano-based macro- and micronutrients that have shown promising results for wheat improvement have been discussed in detail. Understanding several aspects related to the safe usage of nanomaterials and their future perspectives may enhance their successful utilization in terms of economy and fulfillment of nutritional requirements following wheat nano-biofortification.

“…Research has explored that NPs, due to their small size (<100 nm), can pass plant biological barriers, thus allowing efficient delivery of nutrients/micronutrients [4]. Therefore, NPs, as a versatile resource of plant nanobiotechnology, can improve the management of crop disease and crop loss, thereby increasing plant resistance to various environmental biotic and abiotic stressors.…”

Sustainable agricultural practices are still essential due to soil degradation and crop losses. Recently, the relationship between plants and nanoparticles (NPs) attracted scientists’ attention, especially for applications in agricultural production as nanonutrition. Therefore, the present research was carried out to investigate the effect of Fe3O4 NPs at low concentrations (0, 1, 10, and 20 mg/L) on three genotypes of barley (Hordeum vulgare L.) seedlings grown in hydroponic conditions. Significant increases in seedling growth, enhanced chlorophyll quality and quantity, and two miRNA expression levels were observed. Additionally, increased genotoxicity was observed in seedlings grown with NPs. Generally, Fe3O4 NPs at low concentrations could be successfully used as nanonutrition for increasing barley photosynthetic efficiency with consequently enhanced yield. These results are important for a better understanding of the potential impact of Fe3O4 NPs at low concentrations in agricultural crops and the potential of these NPs as nanonutrition for barley growth and yield enhancement. Future studies are needed to investigate the effect of these NPs on the expression of resistance-related genes and chlorophyll synthesis-related gene expression in treated barley seedlings.
