“…However, in our experiment, the nano-Fe 3 O 4 solution increased the protein content by 2.7 and 7.34% in drought and well-watered conditions, respectively, compared to the untreated plants (Table 6). The application of nanofertilizers enhanced the protein content of bean seeds, and the highest content was observed in Fe + Zn treatment (FatollahpourGrangah et al, 2020). These results agree with Abd El-Aziz and Balbaa (2007), who reported that exogenously applied micronutrients, such as Fe and Zn, increased nitrogen percentage and protein content.…”

Drought is one of the most destructive abiotic stresses that impact the growth, physiology, yield, and nutritional quality of seeds of crop plants. In modern agriculture, the use of nanoparticles can be beneficial due to their large surface area and higher potentiality to enter into the plant leaf during foliar application. This study aims to evaluate the effects of foliar spray containing varying doses (0, 100, and 200 ppm) of the nano-iron (Fe3O4) on the growth, physiology, yield, and seed nutritional quality of soybean under drought (40% of field capacity, FC) and well-watered (80% of FC) conditions. Leaf water status, chlorophyll content of leaves, the height of the plant, fresh leaf weight, fresh stem weight, fresh petiole weight, total dry weight, seed yield, and protein and oil content in soybean seeds were found to be suppressed by the applied drought stress. Under both drought (40% of FC) and controlled well-watered (80% of FC) conditions, the foliar application of nano-iron substantially improved the growth, physiology, yield, and quality of soybean seeds. The nanoparticles at 200 ppm increased soybean seed yield by 40.12 and 32.60% in drought and well-watered conditions, respectively, compared to the untreated plants. Furthermore, nano-iron increased the oil content of soybean seeds by 10.14 and 7.87% under drought and well-watered conditions, respectively, compared to the untreated control. Our results indicate that the application of nano-iron improved drought tolerance, yield, and seed quality of soybean, so exogenous foliar sprays of 200 ppm Fe3O4 were more effective than the other treatments in enhancing drought tolerance and can be utilized to reduce losses caused by drought stress in soybean-growing areas.

“…Water deficiency reduced the concentration of nitrogen (N), potassium (K), manganese (Mn), and Zn in plants (Semida et al, 2021), which was a consequence of a reduction in nutrient uptake, transpiration flux, and membrane stability (Dimkpa et al, 2017). The application of NPs (ZnO) through soil and applied by foliar spray significantly improved the uptake of N, phosphorous (P), K, and Zn, and attenuated the adverse effects of DS (Mangena, 2018;Dimkpa et al, 2019;Fatollahpour Grangah et al, 2020;Mustafa et al, 2021;Semida et al, 2021;Akhtar et al, 2022). Ahmed et al (2021) noted that Fe-and Hg-NPs significantly increased N (51%), P (61%), K (27%), calcium (Ca) (53%), and magnesium (Mg) (62%) uptake compared to the control.…”

Drought stress (DS) is a serious challenge for sustaining global crop production and food security. Nanoparticles (NPs) have emerged as an excellent tool to enhance crop production under current rapid climate change and increasing drought intensity. DS negatively affects plant growth, physiological and metabolic processes, and disturbs cellular membranes, nutrient and water uptake, photosynthetic apparatus, and antioxidant activities. The application of NPs protects the membranes, maintains water relationship, and enhances nutrient and water uptake, leading to an appreciable increase in plant growth under DS. NPs protect the photosynthetic apparatus and improve photosynthetic efficiency, accumulation of osmolytes, hormones, and phenolics, antioxidant activities, and gene expression, thus providing better resistance to plants against DS. In this review, we discuss the role of different metal-based NPs to mitigate DS in plants. We also highlighted various research gaps that should be filled in future research studies. This detailed review will be an excellent source of information for future researchers to adopt nanotechnology as an eco-friendly technique to improve drought tolerance.

“…Besides drought stress tolerance, simultaneous alleviation of heavy metal (Cd) tolerance has also been observed by applying nano-ZnO by reducing Cd uptake and oxidative stress (Adrees et al, 2021). Combined application of nano-ZnO and other NPs like nano-Fe resulted in improved morphological and physiological traits in Glycine max and Phaseolus vulgaris (Fatollahpour Grangah et al, 2020;Vaghar et al, 2020). Salehi et al (2021) demonstrated foliar application of ZnONPs and ZnSO 4 to produce more remarkable effects on plant metabolism and performance compared to soil application evident from the morpho-biochemical and omics analysis of P. vulgaris.…”

Biogenic Synthesis of Zinc Nanoparticles, Their Applications, and Toxicity Prospects

Nanofertilizers effectively deliver the micronutrients besides reducing the phytotoxicity and environmental damage associated with chemical fertilizers. Zinc, an essential micronutrient, is significant for chloroplast development, activation of certain enzymes, and primary metabolism. Nano zinc oxide (ZnO) is the most widely used zinc nanoparticle. Concerns regarding the toxicity of conventional physical and chemical methods of synthesizing the nanoparticles have generated the need for a green approach. It involves the biogenic synthesis of metallic nanoparticles using plants and microorganisms. Microbe-mediated biogenic synthesis of metallic nanoparticles is a bottom-up approach in which the functional biomolecules of microbial supernatant reduce the metal ions into its nanoparticles. This review discusses the biological synthesis of nano-ZnO from microorganisms and related aspects such as the mechanism of synthesis, factors affecting the same, methods of application, along with their role in conferring drought stress tolerance to the plants and challenges involved in their large-scale synthesis and applications.
