“… Liang et al (2005) and Farooq et al (2016) reported that tolerance to Cd in maize was obtained by administration of exogenous Si. Exogenous Si treatment in canola declined the adverse impacts of Cd on photosynthesis and other plant growth parameters ( Baryla et al, 2001 ; Bukhari et al, 2021b ). See Table 2 for some recent examples of Si-induced metal tolerance.…”

Sustainable agricultural production is critically antagonistic by fluctuating unfavorable environmental conditions. The introduction of mineral elements emerged as the most exciting and magical aspect, apart from the novel intervention of traditional and applied strategies to defend the abiotic stress conditions. The silicon (Si) has ameliorating impacts by regulating diverse functionalities on enhancing the growth and development of crop plants. Si is categorized as a non-essential element since crop plants accumulate less during normal environmental conditions. Studies on the application of Si in plants highlight the beneficial role of Si during extreme stressful conditions through modulation of several metabolites during abiotic stress conditions. Phytohormones are primary plant metabolites positively regulated by Si during abiotic stress conditions. Phytohormones play a pivotal role in crop plants’ broad-spectrum biochemical and physiological aspects during normal and extreme environmental conditions. Frontline phytohormones include auxin, cytokinin, ethylene, gibberellin, salicylic acid, abscisic acid, brassinosteroids, and jasmonic acid. These phytohormones are internally correlated with Si in regulating abiotic stress tolerance mechanisms. This review explores insights into the role of Si in enhancing the phytohormone metabolism and its role in maintaining the physiological and biochemical well-being of crop plants during diverse abiotic stresses. Moreover, in-depth information about Si’s pivotal role in inducing abiotic stress tolerance in crop plants through metabolic and molecular modulations is elaborated. Furthermore, the potential of various high throughput technologies has also been discussed in improving Si-induced multiple stress tolerance. In addition, a special emphasis is engrossed in the role of Si in achieving sustainable agricultural growth and global food security.

“…For example, in cucumber roots infected with Pythium spp., Cherif et al [22] reported that Si supply induced peroxidase and polyphenoloxidase activities. In particular, in Brassica napus and Brassica juncea exposed to salinity or drought, Si was shown to upregulate a wide range of non-enzymatic (ascorbate and glutathione pools) and enzymatic antioxidants activities [23][24][25][26]. In addition to alleviating drought and salinity stresses, many studies report that Si supply is also beneficial in helping plants overcome main macronutrient (N, P, K) deficiencies.…”

Silicon (Si) is known to alleviate many nutritional stresses. However, in Brassica napus, which is a highly S-demanding species, the Si effect on S deficiency remains undocumented. The aim of this study was to assess whether Si alleviates the negative effects of S deficiency on Brassica napus and modulates root sulfate uptake capacity and S accumulation. For this, Brassica napus plants were cultivated with or without S and supplied or not supplied with Si. The effects of Si on S content, growth, expression of sulfate transporter genes (BnaSultr1.1; BnaSultr1.2) and sulfate transporters activity in roots were monitored. Si supply did not mitigate growth or S status alterations due to S deprivation but moderated the expression of BnaSultr1.1 in S-deprived plants without affecting the activity of root sulfate transporters. The effects of Si on the amount of S taken-up and on S transporter gene expression were also evaluated after 72 h of S resupply. In S-deprived plants, S re-feeding led to a strong decrease in the expression of both S transporter genes as expected, except in Si-treated plants where BnaSultr1.1 expression was maintained over time. This result is discussed in relation to the similar amount of S accumulated regardless of the Si treatment.

“…The effect of silicon (Si) on the major activities of antioxidant enzymes including catalase (CAT), ascorbate peroxidase (APX), peroxidase (POD), chlorophyll contents, accumulation under drought stress in three different growth stages of wheat plants (Triticum aestivum L.) was observed (Sara and Raheem, 2011). The application of Si signi cantly improved the ability of plants to withstand drought stress by improving Si uptake in plants and also improving Si uptake in plants and increased the production Ascorbate peroxidase (APX), peroxidase (POD), superoxide dismutase (SOD) and catalase activities (CAT) (Adnan et al, 2020).…”

Drought stress is considered one of the most severe stresses, which can result in devastating yield reduction in agriculture crops. There are many approaches recommended by the researchers and adopted by the farmers to minimize the devastating effect of drought. However, exogenous application of growth regulators in combination to plant nutrients is the innovative attitude to ameliorate the shocking effects of drought stress. So we planned a study to investigate the ameliorative effect of exogenously applied potassium silicate wheat (Triticum aestivum L.) crop under water deficit conditions. The current study was conducted at the Agronomic Research Farm area, Faculty of Agriculture and Environment, The Islamia University of Bahawalpur. RCBD-Split plot design with four repeats was used. The treatments consist on “T0” (Control), “T1” (exogenous application of potassium silicate @ 1% solution), “T2” (exogenous application of potassium silicate @ 2% solution), “T3” (exogenous application of potassium silicate @ 3% solution). The results of our study revealed that drought stress can significantly affect crop yield as a result of the reduction in chlorophyll-a (1.07), chlorophyll-b (0.49), total chlorophyll contents (1.62), flag leaf area (38.33 cm2), plant height (100.17cm), number of nodes per plant (3.91), tiller height (92.42), number of tillers m− 2 (191.17), spike length (7.58 cm), number of spikes per plant (10.25), number of grains per spike (25.08), 1000-grain weight (36.66g), total dry weight per plant (309.75g), biomass yield (23424kg/ha) and grain yield (4564.2 kg/ha). On the other hand, the exogenous application of potassium silicate at 2% solution showed promising results in terms of ameliorating the drought effect by significantly enhancing chlorophyll-a (1.21), chlorophyll-b (0.64), total chlorophyll contents (1.92), flag leaf area(45.25 cm2), plant height (123.50cm), number of nodes per plant (5.25), tiller height (99.42), number of tillers m− 2 (276.26), spike length (12.92cm), number of spikes per plant (14.25), number of grains per spike (38.33), 1000-grain weight (44.33g), total dry weight per plant (385.00g), biomass yield (24000 kg/ha) and grain yield (5074.8kg/ha). These findings led us to conclude that the exogenous application of potassium silicate has a great ability to compensate for the detrimental effects of drought in wheat crops.
