Resumo: | The aim of the study was to evaluate if the presence of hydrogel affects the physical and chemical properties of the substrate and the ratio of hydrogel in the fertilization rates of developing seedlings. In the substrate with and without hydrogel, it was carried out an analysis for the chemical and physical characteristics. The production of seedlings was conducted in a greenhouse under reduced irrigation using a randomized design factorial arrangement 2 X 6 in which the levels of factor ‘A’ referred to the presence (6 g L-1) or absence of hydrogel and the levels of factor ‘B’ to the doses of controlled-release fertilizer - FLC (0; 25; 50; 75; 100 and 125% of the usual dosage). After 90 days of sowing, there was the evaluation of morphological parameters of seedlings. The use of hydrogel showed improvement of physical and chemical characteristics of the substrate, especially the attributes involving water retention and availability of the plants. Together with the addition of hydrogel and approximately 50-75% of conventional fertilization, there was an increase in height, diameter collect, dry mass, root and all, in addition to the Dickson Quality Index. Along with the use of hydrogel and fertilization over 100%, the growth of seedlings decreased. On the other hand, without the addition of the polymer, the best performance was obtained from seedlings at doses higher than 100% of conventional fertilization. In general, the use of the polymer allows a reduction of at least 25% of the conventional fertilization (6 g L-1), reaching up to 50%. |

No substrato com presença e ausência do hidrogel foi realizada análise de características químicas e físicas. A produção de mudas foi conduzida em casa de vegetação sob irrigação reduzida, utilizando delineamento inteiramente casualizado em arranjo bifatorial 2 x 6, em que os níveis do fator “A” referiram-se a presença (6 g L-1) ou ausência do hidrogel e os níveis do fator “B”, às doses do fertilizante de liberação controlada – FLC (0; 25; 50; 75; 100 e 125% da dose usual). Após 90 dias de semeadura foi realizada a avaliação de parâmetros morfológicos das mudas. O uso do hidrogel apresentou melhoria das características físicas e químicas do substrato, principalmente aos atributos que envolvem retenção e disponibilização de água às plantas. Com a adição do hidrogel e aproximadamente 50-75% da adubação convencional, houve aumento da altura, diâmetro de coleto, massa seca radicular e total, além do índice de qualidade de Dickson. Com o uso do hidrogel e adubação superior a 100% há redução do crescimento das mudas. Já, sem a adição do polímero, o melhor desempenho das mudas é obtido com doses superiores a 100% da adubação convencional. Em geral, o uso do polímero permite a redução em, pelo menos, 25% da adubação convencional (6 g L-1), podendo ser reduzida em até 50%.Universidade Federal de Santa Maria2016-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2510610.5902/1980509825106Ciência Florestal; Vol. 26 No. 4 (2016); 1155-1165Ciência Florestal; v. 26 n. 4 (2016); 1155-11651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/25106/pdfCopyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessNavroski, Marcio CarlosAraújo, Maristela MachadoCunha, Fernando da SilvaBerghetti, Álvaro Luís PasquettiPereira, Mariane de Oliveira2017-04-05T17:12:16Zoai:ojs.pkp.sfu.ca:article/25106Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-05T17:12:16Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
