Resumo: The use of silicate is a practice that has been frequently adopted in annual crops, although few studies have been conducted in order to verify its efficiency in forest tree species. The main objective of this research was to evaluate the effect of calcium and potassium silicates in the growth of seedlings of Eucalyptus grandis. The experiment was conducted in a greenhouse, in Alambari county, State of São Paulo. A completely randomized experimental design was adopted, with eight treatments, three replications and 25 plants per plot, maintained at the field capacity moisture level. Seedlings were planted in plastic tubes using local substrate, basic fertilization and silicates. Diameter, height and fresh and dry biomass of the seedlings were determined 150 days after silicates treatments were applied. The use of silicates either in the substrate or through foliar application, in the production of eucalypt seedlings has proven to be inadequate when the substrate presents a balanced basic composition in terms of nutrients and pH.

O objetivo principal desta pesquisa foi avaliar o efeito da aplicação de silicatos de cálcio e de potássio no crescimento de mudas de Eucalyptus grandis. O experimento foi conduzido em casa de vegetação, no Município de Alambari, SP. O delineamento usado foi inteiramente ao acaso, com oito tratamentos, três repetições e 25 plantas por parcela, sendo mantidas na umidade de capacidade de campo. As mudas foram plantadas em tubetes de plástico, utilizando substrato local, com adubação básica e silicatos. Diâmetro de colo, altura e biomassa verde e seca das mudas foram determinados 150 dias após a aplicação dos silicatos. Verificou-se que a aplicação dos silicatos, via substrato ou foliar, em mudas de eucalipto, mostrou-se inadequada quando o substrato utilizado apresentou composição básica equilibrada em termos de nutrientes e pH.Embrapa Florestas2011-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/15010.4336/2011.pfb.31.66.83Pesquisa Florestal Brasileira; v. 31 n. 66 (2011): abr./jun.; 83Pesquisa Florestal Brasileira; Vol. 31 No. 66 (2011): abr./jun.; 831983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/150/208Copyright (c) 2011 Itamar Antonio Bognola, Lina Avila Clasen, Luziane Franciscon, Jose Luiz Gava, Renato Antonio Dedecek, Fernando Márcio da Silvahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessBognola, Itamar AntonioClasen, Lina AvilaFranciscon, LuzianeGava, Jose LuizDedecek, Renato AntonioSilva, Fernando Márcio da2017-04-28T13:06:42Zoai:pfb.cnpf.embrapa.br/pfb:article/150Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T13:06:42Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
