Nowadays, potassium silicate
is considered as an agronomically essential element because of its beneficial effects of Si, including enhancement of growth and quality, photosynthesis stimulation, transpiration reduction and increasing plant resistance to biotic and abiotic stresses, are well-established in several agricultural crops(Kamenidou et al., 2008).Also the previous studies reported that, the foliar application of amino acids mixture caused an enhancement in plant growth and yield in a number of vegetable crops, potato(El-Zohiri and Asfour, 2009); onion (Shaheen et al., 2010) and beans (Abdel-Mawgoud et al.,2011).
LED lights, an air pump, a humidifier, a dehumidifier, 28 pots, 1 pH meter, grow stones, 1 bottle of potassium silicate
, and other chemicals, were also found in Chen's home, according to CNA.
Chemicals such as Acibenzolar-S-Methyl (ASM), analogue of salicylic acid, organic acids and polyphenols (OAP), compounds derived from microorganisms such as phosphorylated mannan-oligosaccharides from the cell wall of Saccharomyces cerevisiae Meyen (SC) and potassium silicate
(SiK) can trigger the production of signals to various reactions against pathogens, by chemical or structural responses that prevent or delay the entry or colonization of a microorganism in the plant (COSTA et al., 2010).
In this context, given that potassium and nitrogen supply is important for lettuce, and considering the possible benefits that fertilization with silicon can offer to its culture, this study aimed to evaluate the effects of varying doses of nitrogen and potassium silicate
when applied by fertigation on curly lettuce plants, cultivar Vera.
This study aimed to compare vitroplants of Catasetum x apolloi grown under natural light and artificial light and different concentrations of potassium silicate
, providing data on anatomical plasticity that might assist in the acclimation process of this endemic species from the northern Mato Grosso.
Sodium silicate solution ([Na.sub.2]Si[O.sub.3]) and potassium silicate
solution ([K.sub.2]Si[O.sub.3]) were used in some mix designs.
The [Fe.sub.3][O.sub.4] powder, carbon black spherical powder with particle size distribution of 0.4-12 [micro]m, and potassium silicate
solution were purchased from the local market and used as received.
The engineering technology published in 1898 by Sevres Ceramics Factory in France pointed out that modern zinc crystalline glaze was the compound of zinc oxide and potassium silicate
and was the crystal separated out by melting and cooling down in the kiln.
Liu, Slow-Release Potassium Silicate

 who studied the inhibitory effects of potassium silicate
on several soil-borne fungi including V.
Sources of silica were as follows: a solution of commercial potassium silicate
(PS; [K.sub.2]O Si[O.sub.3][H.sub.2]O) produced by the Colombian company "Productos Quimicos Panamericanos S.A."(PQP), which consisted of 13.06% [K.sub.2]O, 26.38% Si[O.sub.2], and 60.56% [H.sub.2]O; a commercial SF called SikaFume[R]; and RHA obtained by controlled heat treatment of rice husks at 600[degrees]C.
Traditionally Si is missing from commonly used plant nutrient solutions; however Si in the form of potassium silicate
([K.sub.2]Si[O.sub.3]) is now available for greenhouse use.
