Resumo: A water absorbent polymer can guarantee plant water supply in regions presenting water deficits. Stockosorb® is an inert acrylic polymer that transforms into a gel when it absorbs water and can later gradually release this water to plants. This research was aimed at studying the effects of the water-holding polymer Stockosorb®, associated or not to organic matter, upon the initial field development of coffee (cv. Catucaí) seedlings. A randomized block design was utilized, in a 2 x 2 x 3 factorial arrangement with four replications totalizing 12 treatments. The following factors were considered: a) two planting systems (SP) (no tillage and conventional); b) two organic matter dosages (MO) (no organic matter and 500 grams per hole); c) three polymer dosages (DP) (no polymer, 3.0, and 6.0 grams per hole). The polymer, in a powdered form, was appplied to the holes before seedling planting. The experiment was carried out at Univesidade Federal de Lavras, in Minas Gerais, Brazil. Planting systems showed significant effect, however, the dosages of organic matter and polymer did not effect the initial plant development.

Um polímero hidroretentor pode garantir o suprimento de água para as plantas em regiões que apresentam deficiência hídrica. O Stocksorb® é um polímero acrílico inerte que ao absorver água passa a constituir um gel, podendo, posteriormente, liberar essa água para a planta, gradativamente. Com o presente trabalho, objetivou-se estudar os efeitos do polímero hidroretentor Stockosorb®, associado ou não a matéria orgânica, sobre o desenvolvimento inicial de mudas de cafeeiro cultivar Catucaí, no campo. Utilizou-se o delineamento em blocos casualizados, em esquema fatorial 2 x 2 x 3 com 4 repetições, num total de 12 tratamentos. Foram utilizados: a) dois sistemas de plantio (SP) (direto e convencional) no primeiro fator; b) duas doses de matéria orgânica (MO) (0,0 e 500 gramas por cova) no segundo fator; c) três doses de polímero (DP) (0,0; 3,0 e 6,0 gramas por cova) no terceiro fator. O polímero, na forma de pó, foi aplicado na cova, antes do plantio. O experimento foi conduzido na Universidade Federal de Lavras. Os sistemas de plantio apresentaram efeito significativo, porém, doses de matéria orgânica e polímero não afetaram o desenvolvimento inicial das plantas.Editora UFLA2007-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/12Coffee Science - ISSN 1984-3909; Vol. 1 No. 1 (2006); p. 7-13Coffee Science; Vol. 1 Núm. 1 (2006); p. 7-13Coffee Science; v. 1 n. 1 (2006); p. 7-131984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/12/8https://coffeescience.ufla.br/index.php/Coffeescience/article/view/12/65https://coffeescience.ufla.br/index.php/Coffeescience/article/view/12/66Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessVale, Geraldo Fernando Rezende doCarvalho, Samuel Pereira dePaiva, Leandro Carlos2013-02-23T12:09:00Zoai:coffeescience.ufla.br:article/12Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:25.446084Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
