“…A dose of 2 mmol L -1 Si added to the nutrient solution, regardless of Si source, increased dry matter yield of shoots (DMYS), roots (DMYR), leaf area, and leaf specific mass (LSM) of rice plants (Table 2). The significant increase of LA, DMYS, and DMYR in rice in response to Si application observed in this work was also observed by several other authors (CHAGAS et al, 2016;MAUAD et al, 2011;ZANÃO JÚNIOR et al, 2010). Rice plants treated with Si accumulate significant amounts of this beneficial element in leaves resulting in a larger leaf area.…”

The objective of this work was to evaluate the effects of various Si sources currently used in studies of Si doses in nutrient solutions on dry matter yield and the accumulation of nutrients and Si in rice plants. Treatments of rice plants with three sources of Si (monossilicic acid, sodium metasilicate, potassium metasilicate) and a treatment without Si were allocated in a randomized block design with ten replications. After 39 days in the nutrient solution, the following traits were evaluated: leaf area, leaf specific mass, dry matter yield of roots and shoots, and levels of K, Na, and Si in leaves and roots. Si increased leaf area, leaf specific mass, and dry matter yield of shoots and roots regardless of the Si source. Levels of Si in leaves and roots were significantly higher in relation to the control treatment but no significant difference among Si sources was identified. It was also observed that K and Na were adequately balanced across the treatments. Thus, a cheaper and easier to obtain Si source, such as sodium metasilicate and potassium metasilicate, may be chosen to carry out studies of Si additions to nutrient solutions.

“…Tem sido verificada correlação linear significativa entre as fertilizações foliares com Si e a DMAP das plantas de arroz (Shi et al, 2013;Cuong et al, 2017), além de maiores produções de massa seca de raízes (DMR) e DMEP de arroz com o aumento do fornecimento de Si (Ramos et al, 2008;Chagas et al, 2016). Em outras gramíneas, a aplicação foliar de Si também tem aumentado a DMAP, como verificado em plantas de milho (Campos et al, 2015) e cana-de-açúcar (Moraes et al, 2011).…”

“…No entanto, para o acúmulo de Si nas raízes, os maiores valores observados (102,14 g planta -1 ) foram observados com o uso de 3,19 g L -1 de Si. O fornecimento de Si para as plantas tem sido considerado viável para absorção e acúmulo do elemento nas plantas (Pereira et al, 2004;Chagas et al, 2016;), pois supre a necessidade nutricional e estimula os efeitos benéficos, principalmente em fertilizações foliares (Sousa et al, 2010), mesmo quando realizado poucas aplicações e baixas doses durante o ciclo das culturas (Soratto et al, 2012). Em pesquisas com a cultura do arroz, tem sido observado que a aplicação de Si foliar aumenta a concentração deste elemento no tecido vegetal, promovendo maior acúmulo pelas plantas (Detmannet al, 2012;Cuong et al, 2017).…”

“…Wang et al (2016) stated that the yield of apples was significantly increased in detriment of the application of Si. Chagas et al (2016), in a study with rice and pearl millet cultivated in the Brazilian savanna, reported that the application of Si increases the yield of these crops. Costa et al (2015) reported increased diameter of the Palmer mangoes associated with the application of Si.…”

Considering that the beneficial effects of silicon on human health and it´s accumulation in plants are little explored, studies of mineral nutrition in non-conventional vegetables are extremely relevant. Thus, the objective of this work was to identify non-conventional vegetables responsive to silica fertilization and evaluate the effect of fertilization on the content and accumulation of Si and macronutrients in these plants. The experiment followed a 4 x 5 factorial design, with four species of non-conventional vegetables (Rumex acetosa L., Amaranthus retroflexus L., Sonchus oleraceus L. and Stachys byzantina) and five doses of Si (0, 25, 50, 100 and 150 mg dm-3). The relative chlorophyll index, the fresh and dry matter masses, the content and accumulation of Si and macronutrients were evaluated. The species A. retroflexus, S. oleraceus. and S. byzantina showed the highest contents and accumulation of Si. The application of doses above 100 mg dm-3 promoted the highest silicon content estimated for the species. The species A. retroflexus, R. acetosa and S. byzantina are non-silicon accumulators, whereas S. oleraceus is intermediate.
