“…Si reduces transpiration due to accumulation in the tissues of cuticles (Keller et al, 2015). The results are in accordance with those of El-Shawa et al (2022) found that the highest increase in plant height, leaf width, stem diameter and leaves the number of philodendron plants duo to 60mg/l AgNPs in compression to control, FeNPs and ZnNPs. And Ismail et al (2022) revealed that SiNPs application at the rate of 3 mM caused a significant increase in plant height, fresh and dry weights and total yield of Pisum sativum plant when compared to the control.…”

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.

“…The application of nano silica and melatonin individually or in combination led to an increased membrane stability, which induced the plant defenses by adjusting the enzymes activity, total phenolic compounds and proline content, which scavenged the ROS and protected the cells of the pea plants from oxidative damage under salt stress compared to the stressed pea plants that did not receive treatments. The helpful effect of SNPs on enzyme regulation was also recorded by Mukarram et al [85], El-Shawa et al [103] and Khedr et al [43]. SiNPs can regulate CAT, APX and SOD activities and the AsA-GSH cycle, which improves the defense system.…”

The effect of nano silica (50 mL L−1) and melatonin (75 µM) individually or in combination in foliar applications on the morphophysiological, biochemical and yield properties of pea plants under salinity stress conditions was evaluated. Salt stress caused a remarkable decrease in the growth and yield characteristics; for example, the plant dry weight, plant height, number of flowers plant−1, number of pods plant−1, weight of 100 green seeds and protein concentration in the pea plants during both seasons were decreased compared with the control. Similarly, their physiobiochemical characteristics were negatively affected; chlorophyll a, chlorophyll b and the relative water content (RWC) were significantly reduced in the stressed pea plants. However, malondialdehyde (MDA), hydrogen peroxide, the electrolyte leakage (EL%), super oxide and the antioxidant components (catalase (CAT), superoxide dismutase (SOD), peroxidase (POX) and total phenolic compounds) were significantly increased when the plants were under salt stress compared with the control plants. On the other hand, the foliar application of nano silica and melatonin individually or in combination enhanced the physiobiochemical characteristics, morphological characteristics and yield of the stressed pea plants. The best treatment was the combination treatment (nano silica + melatonin), which caused significant increases in the plant dry weight, plant height, number of flowers and pods plant−1, weight of 100 green seeds, protein concentration, chlorophyll concentrations and RWC in the stressed pea plants. Additionally, the combination treatment significantly decreased the EL%, MDA, O2⋅− and H2O2 and adjusted the upregulation of the antioxidant enzymes, proline and total phenolic compounds in the stressed plants compared with the stressed untreated pea plants. Generally, it can be suggested that the co-application of nano silica (50 mL L−1) + melatonin (75 µM) plays a positive role in alleviating the adverse impacts of salinity on pea plants by modifying the plant metabolism and regulating the antioxidant defense system as well as scavenging reactive oxygen species.

“…Consequently, the application of Si-NPs could serve as a useful tool for increasing rice's tolerance to oxidative stress by bolstering its enzymatic defences against ROS. In this regard, (Mukarram et al, 2022) (El-Shawa et al, 2022) (Elshayb et al, 2021) reported that the use of Si-NPs increased antioxidant enzymes against oxidative stress. Grain yield is the ultimate product of the physiological processes of different stages of plant development.…”

ATER deficit is a major environmental stress that has a tremendous effect on the physiological processes and productivity of rice. Thus, it is crucial to enhance rice tolerance to drought stress, especially under unpredictable climate changes and the increasing global population. This investigation aimed to study the impact of foliar-supplied nano-silica (Si-NPs) and potassium sulfate (K-sulphate) on some physiological, agronomic characters and crop water productivity of rice plants under water deficit and well-watered conditions during two summer seasons. The experimental design was a spilt-plot with four replications. The main plots were assigned to the two irrigation treatments; every 4 days (well-watered) and 12 days (water-deficit) after transplanting. The sub-plots were allocated by the three foliar treatments, namely, untreated control (distilled water application), foliar application of Si-NPs, and K-sulphate. The results displayed that the foliar applications, irrigation treatments, and their interactions had a significant influence on all the evaluated traits. Drought stress significantly reduced number of panicles per plant, number of grains per panicle, 1000-grain weight, and grain yield. However, water deficit considerably elevated antioxidant enzymes catalase (CAT) and peroxidase (POD) proline content compared to well-watered conditions. The foliar application of Si-NPs and K-sulphate was efficient in boosting drought tolerance by promoting antioxidant enzymes (CAT and POD) as well as proline accumulation compared with untreated plants. These positive influences were displayed in improving grain yield and its related traits as well as crop water productivity under drought stress conditions. Consequently, the utilization of foliar-applied Si-NPs and K-sulphate represents an applicable approach to enhance yield traits and crop water productivity of rice under water shortage conditions.
