“…Monalisa. Ayman et al (2020) showed that SiNPs by soil or by spraying significantly improved the uptake of N, P and K content and reduced the uptake of Na + content in wheat seedlings. As for the combined effects of DSW levels and used concentrations of NPs of Si and Ag, data tabulated in Table (10 and 11) cleared that the different used combinations of the applied factors had various exhibit impacts on the chemical composition of D. erecta…”

Evergreen shrub Duranta erecta "Golden Edge" is utilized for ledges, summer color, and expanding specimens in landscaped gardens. It is projected that the landscaping and gardening of these places will suffer due to a lack of non-saline irrigation water and fewer ornamental species that can grow in these conditions. Thus, pot experiments were conducted in the seasons of 2021 and 2022 to investigate the impact of diluted seawater (DSW), which was assigned as the main plot, and nano-silica (SiO2NPs) and nano-silver (AgNO3NPs), which were situated as the subplot. The data gathered indicated that the "Golden Edge" D. erecta survival rate was 100% up to 30% DSW. Whitest at 40 and 50%, there was little chance of survival. DSW levels had adverse effects on vegetative growth traits (plant height, branches per plant, stem diameter, fresh and dry weights of aerial parts, roots per plant, and leaf greenness degree), chemical composition (N, P, K, Si and total carbohydrates and water content%), and relative to the control (tap water). With rising DSW% during the two seasons, the values of these attributes significantly and gradually dropped. On the other hand, DSW increased proline content, Na, and Cl% when compared to the control. Nevertheless, SiO2NPs and AgNO3NPs applications at 150 and 300 mg/l of each considerably enhanced vegetative and chemical features except for Na and Cl%, which decreased in comparison to the control. In some cases, the rate of 300 mg/l AgNO3NPs and 300 mg/l SiO2NPs had no appreciable variations in their effects on the maximum significant values of vegetative characteristics, N, P, K, total carbohydrates %, and proline content. While the control had the highest Na and Cl% results. The highest plant water content and Si content were given at the same time by 150 and 300 mg/l SiO2NPs. The interaction between 300 mg/l AgNO3NPs and irrigation with tap water (control) produced the greatest values of the abovementioned traits, apart from Na and Cl% and proline content, whose highest values were recorded for the plants irrigated by 30% DSW combined with non-sprayed and 300 mg/l AgNPs, respectively. Also, the plants that received tap water irrigation and were successively sprayed with 150 and 300 mg of SiO2NPs during the two seasons had the highest water content.

“…In addition, it may be because of the effect that the nano-fertilizer particles have on the various metabolic reactions in the plant [35,36], and the role of effective foliar nano-fertilizers in increasing the speed of enzymatic and biological reactions due to the large surface area of nanoparticles leading to an increase in the production of flower initiators and their numbers, and thus the number of grains per panicles and the number of panicles and its role in stimulating the action of enzymes and increasing the activity of chemical reactions and reducing the effect of free radicals that negatively affect the efficiency of the work of some organelles in plants [37]. In addition, the improvement in the vegetative development features of the oats plants, as well as the rise in the number of panicles and the number of grains per panicle, contributed to the overall increase in the yield of oats grains that was seen throughout the experiment [38][39][40]. The interaction between the two varieties and the nano-silicon spraying achieved a significant effect, with the interaction between the Shifa variety and the high concentration of nanosilicon 2 ml L -1 achieving superior results in terms of the number of panicles, the number of grains in the panicles, and the grains yield ton.ha -1 , respectively.…”

A field experiment was conducted in the winter of 2021-2022 in the Babel Governorate-Al-Shomali district, which is 68 km southeast of the city of Hilla, to examine the effect of spraying nano-silicone on some characteristics of vegetative growth and yield of two cultivars of oats. A two-factor experiment with three replicates was carried out using a randomized complete block design (RCBD). Both Shefaa and Carlop oats were used in the first factor, and in the second factor, nano-silicon was sprayed at 0, 1, and 2 ml L-1. The results showed that the Carlop cultivar significantly excelled and recorded the highest averages in plant height and flag leaf area when treated with nano-silicone sprays, as well as in the characteristics of growth, yield, and its components. When compared to the control treatment (spraying only distilled water), the cultivar Shifa produced higher averages of cuttings per square meter, panicles per square meter, and grains per hectare than its counterpart. Nano-silicone spraying at 2 ml L-1 resulted in considerably higher plant height, flag leaf area, chlorophyll content, number of tillers, number of panicles per m2, biological yield, and grains production (7.294 tons ha-1) compared to the other treatments. Because of the high averages obtained in most of the attributes investigated, it is clear that the interaction between the Shifa cultivar and sprays of nano silicon had a substantial effect.

“…Due to the stimulation of plant photosynthesis by SiO 2 nanoparticles, silicon plays a critical role in improving the plant antioxidant system's efficiency, promoting plant growth under salt stress, and increasing the plant's tolerance to abiotic and biotic stressors. Therefore, SiO 2 nanoparticles provide excellent solutions for enhancing the capabilities of the soil to support agricultural activities [12,22]. TiO 2 nanoparticles have several uses in agroecosystems due to their attractive physical and chemical characteristics, availability, cheap cost, and excellent stability.…”

Nanotechnology can change agricultural systems and methods used via nanofertilization. It contributes to reducing pollution, protecting the environment, as well as reducing the costs of using chemical fertilizers. Nanofertilizers provide soluble nutrients that are quickly absorbed and reduce their build-up in the soil. Also, it increases plant growth and development and enhances plant resistance to biotic and abiotic stresses. Nanofertilizers' effect on plants varies according to the plant type, method of application, and the size and concentration of different nanoparticles. Moreover, it is necessary to highlight their adverse effects related to toxicity. In addition, we will discuss the future prospects for the use of nanofertilizers. Mechanisms of the effect of nanofertilizer in: 1- Plant growth and development 2- Crop yield 3- Soil fertility 4- The relationship between nanofertilizer and stresses 5- The role of nanofertilizer in environmental protect 6- Toxicity of nanofertilizer 7- The future prospects
