“…The aim of research conducted in the years 2009–2010 in Poland was to determine the impact of the application of silicon (0, 250, 500, or 750 mg·dm −3 ) and manganese (5.2 or 52.0 mg·dm −3 ) on the size and chemical composition of heads of lettuce cv. Omega F1 cultivated in a greenhouse [ 47 ]. Silicon was applied to the substrate once when putting on an aqueous solution of colloidal silica.…”

This paper presents a research review of the effect of silicon fertilization on the yield quantity and quality in the last 15 years. The study focuses on plant species grown in Europe: cereals, soybean, rapeseed, sugar beet, potato, meadows, berries and vegetables, and orchard and ornamental plants. The use of silicon is most common in the production of vegetables in greenhouses. However, the use of this element for the fertilization of agricultural plants is rare. Positive prospects of silicon fertilization are associated with foliar application, which is much cheaper and more convenient to use than soil fertilization. Foliar application of silicon has a biostimulative effect, and the best results are observed in stressful conditions for plants such as salinity, deficiency or excess of water, high and low temperature, and the strong pressure of diseases and pests, etc. Based on the results of previous studies, it can be concluded that foliar nutrition should be introduced into production as a standard treatment in the crop management of many species of agricultural plants. It can help farmers to increase the yield of crops. It is also important that it is safe for the environment, which is particularly important in Europe.

“…Soil application of calcium silicate increased the content of silicon, phosphorus, calcium and copper, and lowered the amount of nitrogen, potassium, manganese and zinc in rice leaves (Fallah 2016). The silicon-fed lettuce contained significantly more phosphorus and potassium as well as less manganese compared to the control plants in which this element was not applied (Jarosz 2015). The use of Actisil fertilization by fertigation in the cultivation of lettuce on mineral wool with a high content of manganese in the medium significantly influenced the content of macronutrients in the above-ground parts of plants by reducing the nitrogen content and increasing the content of phosphorus, potassium, calcium and magnesium compared to the control.…”

The effect of marine calcite, a mixture of ortho- and polysilicic acid as well as orthosilicic acid applied as a foliar spray on the chemical composition of sugar beet leaves in the critical phase of nutrient supply (beginning of July) but also leaves and roots during harvest time in 2015–2016, was studied. The content of silicon in the leaves ranged from 1.24 to 2.36 g kg−1 d.m. at the beginning of July, 3.85–5.34 g kg−1 d.m. during harvest and 2.91–4.20 g kg−1 d.m. in the roots. The foliar application of silicon caused a significant increase in the content of magnesium and calcium in leaves (in July) as compared to the control. The sugar beet consumes approx. 75 kg Si ha−1, which is almost 3.5 times more than P and 20% more than Mg thus proving its importance for its species. About 70% of the silicon taken up by sugar beet is stored in roots and 30% in leaves. The pure sugar yield is most favorably influenced by two- and threefold foliar application of the product containing silicon in the form of orthosilicic acid stabilized with choline, and a threefold mixture of ortho- and polysilicic acid. The increase in the pure sugar yield is not the result of a change in the chemical composition of sugar beet plants, but their more efficient functioning after foliar application of silicon under stress conditions caused by water shortage.

“…Changes in the uptake of components and consequently changes in the chemical composition of plants should be treated as their adaptation to specific environmental factors. For example, the uptake and the translocation of nutrients in plants can be modified by silicon [48]. Also drought stress significantly increased the content of K, Na, Ca, Mg, and Fe in plants, whereas silicon treatment reduced the content of these elements [4].…”

Application of selenium and silicon to alleviate short-term drought stress in French marigold (Tagetes patula L.) as a model plant species

et al. 2020

Selenium (Se) and silicon (Si) are the beneficial elements that may significantly modify plants’ tolerance to various types of biotic and abiotic stress. They may be particularly important due to the current climate changes. The aim of model experiments was to assess how selenium and silicon could alleviate short-term drought stress in French marigold (Tagetes patula L. “Pascal”). Tagetes plant species are economically important annual plants and are also very popular decorative flowering species in city parks due to its beautiful colored flowers and resistance on drought stress. Silicon was applied in the form of silica sol and choline-stabilized orthosilicic acid (ch-OSA). Selenium was applied in the form of sodium selenate (Na2SeO4). They were tested at the following concentrations (mg dm−3 of NS): silica sol – level I (23.25), level II (31.0); ch-OSA – level I (0.21), level II (0.63); and Se – level I (0.4), level II (0.8). The experiment showed that silicon had stimulating effect on the biometric parameters of control plants cultivated under an optimal water regime. When the plants treated with selenium were exposed to stress, the values of their biometric parameters were generally higher than in the plants treated with silicon. Both silicon and selenium significantly modified the gas exchange parameters. During the growing season, the net photosynthesis activity (PN), stomatal conductance (gs), and transpiration rate (E) tended to decrease, but they increased significantly when selenium and silicon were applied. In general, the factors significantly modified the plants’ content of macro- and micronutrients as well as the proportions between them. Both selenium and silicon alleviated the short-term drought stress in French marigolds as a model plant, but when silicon was applied, the positive effect was modified by the source and its concentration.
