“…Still regarding shoot development, studies performed with other plant groups also showed increased plant height, such as for rice (Zanetti et al, 2016;Couto et al, 2020), passion fruit (Costa et al, 2016), potato (Soratto et al, 2019), peanut (Dong et al, 2018), sunflower (Flores et al, 2018b), and tomatoes when not subjected to water stress (Moraes et al, 2020). Therefore, evidence demonstrates that for this parameter Si is highly responsive, and can be an alternative resource for plant development, especially for foliar application, as evidenced by the present study.…”

“…Another important feature is its ability to accumulate silicon (Si) (Epstein, 2009). Although studies on Si for this crop are incipient, its application has shown promising results, increasing yield when applied to Si-accumulating plants such as rice (Couto et al, 2020), sugarcane , maize (Oliveira et al, 2020a), sorghum (Flores et al, 2018a;Oliveira et al, 2020a), sunflower (Flores et al, 2018b;Peixoto et al, 2020), industrial processing tomato (Moraes et al, 2020), and wheat (Qamar et al, 2020).…”

“…However, soil application requires high doses mainly due to the low solubility of silicates used (Lanna et al, 2016). Si sources with high solubility are alternatives, with foliar application being efficient to supply Si to grasses (Flores et al, 2018a;Couto et al, 2020;, increasing Si uptake and transport efficiency in plants (Flores et al, 2018b), and increasing dry biomass production.…”

Millet is a grass that has been highlighted for silage production, especially for being a productive tropical plant, and undemanding concerning soil fertility. Silicon (Si) is an alternative low-cost solution to increase biomass production, and it has been noticed to be beneficial to plants, especially when there are stress conditions. So, we analyzed the effects of foliar silicon application to gas exchanges, dry biomass production, and economic efficiency. We used a completely randomized experimental design consisting of foliar application of the following five doses of Si: 0; 0.84; 1.68; 2.52; and 3.36 g L-1 of Si as potassium and sodium silicate, with five replications. We measured the plant height, leaf area, Si contents and accumulation in the plants, gas exchanges (stomatal conductance, transpiration, and photosynthesis net), dry matter production, Si uptake and transport efficiency by plants and its economic efficiency. The Si content enhanced and accumulated in all parts of millet plants, reaching values between 2.5 and 3.3 g L-1. There were linear increases of approximately 9 and 27% in height and leaf area of millet plants to 3.36 g L-1 of Si. Stomatal conductance and transpiration reached maximum values representing an increase of 44.60 and 101.30%, respectively. The concentration of 3.36 g L-1 of Si increased photosynthesis by 76% and shoot dry matter production by 15%, when compared to the control. Si application is economically viable. The operational costs of application are suppressed, reaching to about US $ 45.32 ha-1 with the application of 2.52 g L-1 of Si.

“…The increase in Si by plants does not have a direct relationship with the production of biomass and it not considered an essential element for the plant cycle, however the results of its use can be satisfactory or because a decrease in development according to the quantity adopted. According to Couto et al (2020), utilization showed efficiency with maximum estimated dose for application in rice of 1.68 g L -1 , using sodium and potassium silicate stabilized with sorbitol as a source. Positive results, through the application of Si, also reported in the productive performance and in the post-harvest of cauliflower (BARRETO et al, 2017;CURVELO et al, 2019;HOSSAIN et al, 2020).…”

The production of seedlings is an important step in the establishmentof the crop, with repercussions on yield, whose application of Si can improve phytosanitary and performance characteristics.The objective of the study was to analyze the increase of silicon in substrate on the development of seedlings of Brassica oleraceavar. botrytis. The experiment carried out in randomized blocks, with five amounts of silicon (0, 25, 50, 75 and 100 g kg-1of substrate) and four replications. Silicon oxide (98% SiO2) used, mixed with the substrate with subsequent filling of the polyethylene trays (128 cells) and seeding. The trays kept in a greenhouse. At 30 days after sowing, the height of seedlings, number of leaves, fresh weight of leaves and stem, dry weight of leaves, stem and root evaluated. The data subjected to analysis of variance by the F test and regression analysis. Of the variables analyzed, only the dry root mass did not show a significant difference. Quadratic models can represent the variation in components. Seedling height increased with the increase of silicon up to thedoseof 75 g kg-1. Other variables showed increases up to a dose of 50 g kg-1. The increase of silicon in the substrate was efficient in the development of seedlings of Brassica oleraceavar. botrytisin an amount of up to 50 g kg-1of substrate.

“…Couto et al (2020) avaliaram a aplicação de silício via foliar no crescimento, biomassa e qualidade fisiológica do arroz. Nesse ensaio foi feita a aplicação de doses crescentes de silicato de sódio e potássio os autores observaram que a qualidade fisiológica das plantas de arroz não é afetada pela aplicação de silício e foi observado que com a aplicação da dose superior a 1,68 g L -1 há uma redução no aproveitamento do silício pela planta Oliveira et al (2020).…”

RESUMONos solos o silício está presente na forma de sílica (SiO2) e a origem desse elemento no solo ocorre através do intemperismo de argilominerais, entretanto, a concentração desse elemento no solo é reduzida de acordo com o grau de intemperismo por ele sofrido, por isso, quanto maior o grau de intemperismo, menor será a concentração de silício no solo, além disso, cultivos contínuos também reduzem a concentração do silício no solo. Do ponto de vista nutricional o silício é classificado como elemento benéfico, ou seja, a planta é capaz de se desenvolver sem a presença do silício, mas a sua aplicação contribui para um melhor desenvolvimento e consequentemente para uma maior produtividade. O objetivo desse presente trabalho foi analisar o efeito do silício no solo e na planta, assim como as fontes que vem sendo utilizadas e modos de aplicação, através da busca trabalhos já publicados. Foi realizada uma busca utilizando as palavras-chaves "Silicon+ Sources+agriculture application", nessa busca foram encontrados 4.276 trabalhos publicados desde de 2000 até 2020, desses, 4.062 estavam revisados por pares. Realizou-se a seleção de trabalhos após uma leitura dos títulos e o critério utilizado foi selecionar aqueles que estavam diretamente ligados com fontes de silício e forma de aplicação na agricultura. Quanto as fontes são muitas as utilizadas (silicato de cálcio, casca de arroz, pó de rocha, silicato de potássio, farinha de rocha, xisto). E são aplicadas via solo como corretivo ou fertilizante, e via foliar. A aplicação de silício aumenta o acumulo do mesmo nos tecidos vegetais das plantas e diversas fontes de silício, independente do teor de silício total, mostraram ser eficientes tanto aplicadas via solo ou via foliar.
