Resumo: | The aim of this work was to evaluate the treated sewage sludge (LET) associated with commercial substrate based on pinus bark (SC1) or based on coconut fiber (SC2), in different proportions, as substrate for the production of vinatic seedlings. The study was led in a greenhouse, located in the research support unit of the State University of North Fluminense. The treatments considered as substrates were 20, 40, 60, 80% of LET associated with SC1 or SC2, 100% of LET and the treatment with SC1 with conventional fertilization (control). The sewage sludge was sanitized with addition of lime to 15% of dry weight. The results showed that the lower LET proportions in the substrate resulted in seedlings with better growth in height, stem diameter, leaf area, dry mass of shoot and root system, root length and volume. The nodulation was negatively influenced in the seedlings produced in proportions above 20% LET. The aggregation of the clod was not influenced by the addition of LET, however, there was increase of the curvature of the clod in the seedlings produced in larger amounts of LET. The shoot content of N, P and K was lower in the seedlings with LET. For the production of vinatic seedlings, 20% of sewage sludge associated with SC1 or SC2, is suggested, with no losses in relation to the seedlings produced in commercial substrate thatreceived fertilization, used commercially. |

O experimento foi conduzido em casa de vegetação, localizada na unidade de apoio a pesquisa da Universidade Estadual do Norte Fluminense, de junho a novembro de 2016. Utilizaram-se 20, 40, 60, 80% de LET associados ao SC1 ou ao SC2, 100% de LET e o tratamento com SC1 com adubação convencional (controle). O lodo de esgoto foi higienizado com adição de cal a 15% do peso seco. Os resultados revelam que as menores proporções de LET no substrato resultaram em mudas com melhor crescimento em altura, diâmetro do coleto, área foliar, massa seca da parte aérea e do sistema radicular, comprimento e volume radicular. A nodulação foi negativamente influenciada nas mudas produzidas em proporções acima de 20% de LET. A agregação do torrão ao substrato não foi influenciada pela adição de LET, entretanto, houve aumento da curvatura do torrão nas mudas produzidas em maiores quantidades de LET. O conteúdo da parte aérea de N, P e K foi menor nas mudas produzidas em substrato com LET. Para produção de mudas de vinhático, sugere-se a proporção de 20% de lodo de esgoto associado ao SC1 ou SC2, não havendo prejuízos em relação às mudas produzidas em substrato comercial adubado, utilizado comercialmente.Universidade Federal de Santa Maria2019-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2729710.5902/1980509827297Ciência Florestal; Vol. 29 No. 2 (2019); 728-739Ciência Florestal; v. 29 n. 2 (2019); 728-7391980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27297/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessSiqueira, David PessanhaBarroso, Deborah GuerraWeiss de Carvalho, Giovanna Campos MamedeErthal, Rommel MonneratRodrigues, Maria Clara CoutinhoMarciano, Claudio Roberto2019-09-05T20:40:55Zoai:ojs.pkp.sfu.ca:article/27297Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-09-05T20:40:55Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
