“…The application of Zn-NPs improved the values of antioxidant enzymes, and the results are in agreement with the findings of Rizwan et al [33] on maize (Zea mays L.). Metal NPs inhibit ROS formation by improving the antioxidant activity of the plant cells [34]. The increase in catalase activity in plants treated with Zn-NPs suggests that NPs can effectively modify the enzyme activity.…”

The study investigated the green and chemical approaches for the preparation of Zn nanoparticles and their effect on the growth of okra plants under saline conditions. The leaf extract of Sorghum bicolor L. was used for the green synthesis of zinc nanoparticles (Zn-GNPs). Zinc nanoparticles (Zn-NPs) were also produced by the co-precipitation method (Zn-CNPs). The synthesized NPs were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliarly in the range of 0.1%, 0.2%, 0.3% on okra plants. A marked increase in the shoot and root fresh and dry weight (g) and chlorophyll contents were observed under normal and saline conditions. An increase in antioxidant activity was observed under saline conditions. However, the foliar application of 0.3% Zn-GNPs was helpful in the regulation of the antioxidant defense system under a saline environment. Based on the results, it can be concluded that the use of Zn-GNPs is the most promising eco-friendly approach in mitigating salinity stress.

“…While Fe may have been required in excess to maintain photosynthesis, when K was low, other micronutrients may be implicated in the regulation of reactive oxygen species (ROS) and protection of cell membranes. Examples of such micronutrients include Se, involved in the production or regeneration of antioxidant enzymes such as glutathione and catalase [45]; Mn, a cofactor for the antioxidant enzyme superoxide dismutase [46]; and Zn, a scavenger of ROS and protector of cell membranes under salt stress [47]. affecting N tissue accumulation, regardless of K dose.…”

Two spinach (Spinacea oleracea L.) cultivars were evaluated for their response to deficient (0.25 mmol c L −1 or 0.25 K) and sufficient (5.0 mmol c L −1 or 5.0 K) potassium (K) levels combined with salinities of 5, 30, 60, 90, and 120 mmol c L −1 NaCl. Plants substituted K for Na proportionally with salinity within each K dose. Plants favored K + over Na + , regardless of salinity, accumulating significantly less Na at 5.0 K than at 0.25 K. Salinity had no effect on N, P, and K shoot accumulation, suggesting that spinach plants can maintain NPK homeostasis even at low soil K. Ca and Mg decreased with salinity, but plants showed no deficiency. There was no Na + to K + or Cl − to NO 3 − competition, and shoot biomass decrease was attributed to excessive NaCl accumulation. Overall, 'Raccoon' and 'Gazelle' biomasses were similar regardless of K dose but 'Raccoon' outproduced 'Gazelle' at 5.0 K at the two highest salinity levels, indicating that 'Raccoon' may outperform 'Gazelle' at higher NaCl concentrations. At low K, Na may be required by 'Raccoon', but not 'Gazelle'. This study suggested that spinach can be cultivated with recycled waters of moderate salinity, and less potassium than recommended, leading to savings on crop input and decreasing crop environmental footprint.

“…Although many nanoparticles have been applied as nano-fertilizers or nano-pesticides, which promote crop productivity, but might cause some problems in soil-plant interfaces particularly the over-doses ( Ragab and Saad-Allah, 2020 ). Several studies have depicted applied engineered-NPs as nano-fertilizers (e.g., Guo et al, 2018 ; Farshchi et al, 2021 ; Madzokere et al, 2021 ) to improve crop productivity under many stresses ( Ye et al, 2019 , Landa, 2021 ) like drought ( Sreelakshmi et al, 2020 , Ahmed et al, 2021 , Ali et al, 2021 ), salinity ( Manzoor et al, 2021 , Zulfiqar and Ashraf, 2021 ), pollution of heavy metals ( Noman et al, 2020 , Xin et al, 2020 , Manzoor et al, 2021 ), and biotic stress ( Tauseef et al, 2021a , Tauseef et al, 2021b ). These nanoparticles can enhance cultivated plants under stress through many mechanisms such as improving antioxidant defense system, promoting photosynthesis, increasing water, nutrient and phytohormones ( Zulfiqar and Ashraf, 2021 ).…”

Human health and its improvement are the main target of several studies related to medical, agricultural and industrial sciences. The human health is the primary conclusion of many studies. The improving of human health may include supplying the people with enough and safe nutrients against malnutrition to fight against multiple diseases like COVID-19. Biofortification is a process by which the edible plants can be enriched with essential nutrients for human health against malnutrition. After the great success of biofortification approach in the human struggle against malnutrition, a new biotechnological tool in enriching the crops with essential nutrients in the form of nanoparticles to supplement human diet with balanced diet is called nano-biofortification. Nano biofortification can be achieved by applying the nano particles of essential nutrients (e.g., Cu, Fe, Se and Zn) foliar or their nano-fertilizers in soils or waters. Not all essential nutrients for human nutrition can be biofortified in the nano-form using all edible plants but there are several obstacles prevent this approach. These stumbling blocks are increased due to COVID-19 and its problems including the global trade, global breakdown between countries, and global crisis of food production. The main target of this review was to evaluate the nano-biofortification process and its using against malnutrition as a new approach in the era of COVID-19. This review also opens many questions, which are needed to be answered like is nano-biofortification a promising solution against malnutrition? Is COVID-19 will increase the global crisis of malnutrition? What is the best method of applied nano-nutrients to achieve nano-biofortification? What are the challenges of nano-biofortification during and post of the COVID-19?
