“…Gomaa et al (2021), who noted that the greatest values of 100-pod weight, number of pods/plant and pod yield/fed were recorded when peanut crop were irrigated after depletion of 55% available soil water under foliar application of potassium silicate, compared to depletion of 70 and 85% available soil water and tap water application. Foliar application of K-silicate not only increased seed yield, yield components, and oil content under fully irrigated but also alleviated the harmful effects of drought stress on rapeseed plants (Shirani Rad et al, 2022). Furthermore, results clearly indicated that spraying sesame intercropped with peanut with K-silicate could mitigate the reduction in the applied irrigation.…”

Climate changes are increasing over time, adversely affecting water availability and crop productivity. Potassium silicate (K-Si) or Triacontanol (TRIA) reportedly plays an important role in mitigating water stress conditions. A two-year field experiment was carried out during the 2021 and 2022 growing seasons to assess the effect of three irrigation treatments as 120, 100 and 80% of reference evapotranspiration (ETo) and foliar spraying with K-Si and TRIA, compared to control (no spraying) on the yield, water and land equivalent ratio as well as farmer's benefits of sesame intercropped with peanut system (33% S: 100% P). The average values of applied irrigation water were 9654, 8045 and 6436 m 3 /ha for irrigation with 120, 100 and 80% ETo, respectively. The results indicated that the highest yield of both crops was obtained under irrigation with 120% ETo and spraying with K-Si. Foliar spraying with K-Si or TRIA mitigates the adverse effects of low irrigation water application and its adverse effects on yield and its components in both crops under study. Irrigation with 100% ETo (saved 17% of the applied water under 120% ETo) and spraying with K-Si produced a higher yield of both crops than the obtained under irrigation with 120% ETo and no spraying. Furthermore, the highest value of water equivalent ratio (WER), land equivalent ratio (LER), total income (TI) and monetary advantage index (MAI) of sesame intercropped with peanut system were found under irrigation with 120% ETo and spraying with K-Si. However, irrigation with 100% ETo and spraying with K-Si produced higher values of these indices than the obtained under irrigation with 120% ETo and no spraying. Thus, it could be concluded that, to increase the productivity of unit land and water (LER and WER), as well as TI and MAI of sesame intercropped with peanut, irrigation with 120% ETo and spraying with K-Si should be utilized. Furthermore, to save 17% of the applied irrigation water, irrigation with 100% ETo and spraying with K-Si can be used and that obtained higher values of LER, WER, TI and MAI, than the obtained under irrigation with 120% ETo and no spraying.

“…In a similar vein, numerous studies have shown that silicon nanoparticles increase the antioxidant activity of various crops [51], [52], [53], [54]. Thus, potassium silicate treatment increases SOD, glutathione reductase [19], and catalase activities [55], slightly balancing the negative effects of drought on plants. Cotton growth and development are impeded during droughts because of uctuations in the nutrition balance [56].…”

“…Considering its signi cant nature of this concept offers numerous potential bene ts to plant functions and has been massive interest in evaluating different sources of silicon (Si) for the improvement of abiotic stress tolerance in various agricultural crops [17]. Consequently, foliar applied K-Si improved the tolerances of cotton to salinity stress [18], rapeseed (Brassica napus L.) cultivars to drought [19], maize crop (Zea mays L.) [20], [21], Banana (Musa acuminata L.) [22], Faba bean (Vicia faba L.) [23], Ajwain (Trachyspermum ammi L.) [24], Sorghum (Sorghum bicolor (L.) [25], Wheat (Triticum aestivum L.) [26], and other crop are reported. These reports showed that the imperative use of potassium silicate in plant abiotic stress and their management.…”

Cotton is a highly sensitive crop to drought stress. Consequently, it is crucial to devise strategies that optimize crop production in conditions of limited water availability. While potassium silicate has demonstrated effectiveness in mitigating drought stress in various crops, its specific impact on different cotton cultivars under drought conditions remains not fully clarified. This research aimed to assess the efficacy of six potassium silicate levels (ranging from 0, 100, 200, 300, 400 and 500 mg L-1) on four cotton cultivars (Zong main-113, Xin Nong-525, Xin lu Zhong-55, and Xin lu Zhong-66) under two field capacity levels (80% and 50% FC) in a sand culture. The application of foliar potassium silicate significantly improved photosynthetic efficiency, shoot biomass, root biomass, and leaf area under 50% FC. The most substantial reduction in H2O2, malondialdehyde levels, and electrolyte leakage was recorded with potassium silicate applied at a rate of 400 mg L-1. This concentration effectively mitigated reactive oxygen species accumulation, safeguarding plants against oxidative damage at 50% FC. Furthermore, potassium silicate contributed to maintaining water status, resulting in increased leaf water content and elevated water-soluble proteins in cotton plants. This research recommended that the foliar application of potassium silicate at a concentration of 400 mg L-1 significantly enhances cotton's resistance to drought, offering valuable insights for sustainable cotton cultivation in water-limited environments.

The aim of the study was the evaluation of silicon foliar application on sugar beet yield. In the years 2017–2019, the effect of a single foliar application of various forms of silicon (potassium silicate—PS, calcium silicate—CS, sodium metasilicate—SM, and orthosilicic stabilized acid—OSA) applied in the six-leaf phase of sugar beet, 7 and 14 days later on yield and technological quality of sugar beet roots was assessed. It was found that the form of silicon does not have a significant effect on the yield of sugar beet roots, and significantly modifies the biological yield of sugar and the pure sugar yield. The highest biological yield of sugar is achieved by the foliar application of PS, and the pure sugar yield by PS and OSA. The date of foliar application as well as the interaction of the date of application and silicon forms do not have a significant effect on the root yield, biological yield of sugar, and pure sugar yield. The form of silicon has a significant effect on the technological quality of sugar beet roots (sugar, α-amino nitrogen, potassium, and sodium content). The most beneficial effect on the sugar content and reduction of sodium content in sugar beet roots is the foliar application of OSA, and the reduction of α-amino nitrogen and potassium content—PS. The timing of the application of various forms of silicon has a significant effect on the sugar and potassium content in sugar beet roots. The most beneficial effect on the sugar content in the roots is the application carried out 7 days after the six-leaf phase of sugar beet, and the potassium content is most limited by the treatment 14 days after reaching this phase. The interaction of the timing of foliar application and the form of silicon significantly modifies the technological quality features of sugar beet roots: the content of sugar, α-amino nitrogen, potassium, and sodium. The results of the study proved the significant effect of silicon foliar application on the physiological parameters of plants, such as leaf area index (LAI), absorption of photosynthetically active radiation (PAR) and normalized difference vegetation index (NDVI) which are related to yield and sugar beet productivity.
