Resumo: Coffee is a crop with high economical importance to Brazil. It is cultivated on about 2,4 millions hectares spread in almost all the country. Nitrogen fertilizers are routinely used by coffee growers and alternatives to reduce their applications are important. In this study, coffee plants (Coffea canephora Pierre ex Froehn) intercroped with gliricídia (Gliricidia sepium (Jacq.) Steud.) and banana (Musa paradisiaca L.) and banana alone for shade were evaluated. After pruning of gliricidia, their leaves and branches were analysed for the biomass, decomposition rate and their influence on coffee nitrogen nutrition. Gliricidia demonstrated to be an important source of nitrogen for coffee, since it maintains the leaves above the critical levels, as compared to coffee with banana alone treatment, independently of the pruning process. Gliricidia branches were not an important source of Nitrogen due to their low content in nutrients and slow decomposition rate, reaching only 30% of the total in a period of 6 months, while the half life for leaves was 19 days.

O uso de fertilizantes, entre eles o nitrogenado, é bastante difundido. Alternativas que possam reduzir a necessidade de aplicação deste nutriente são importantes. Neste estudo avaliou-se o efeito do cultivo do cafeeiro (Coffea canephora Pierre ex Froehn) sombreado com Gliricidia sepium (Jacq.) Steud. e bananeira (Musa paradisíaca L.), em comparação com o café crescendo somente com a bananeira. Foram determinados, após a poda da gliricidia, a biomassa e a taxa de decomposição de folhas e ramos, e suas influências na nutrição nitrogenada do cafeeiro. A gliricídia se comportou como importante fonte de N para o café, cujos teores em folhas mantiveram-se acima do nível crítico, quando comparado ao café cultivado somente com a banana, independentemente da realização de podas. Os ramos da gliricídia tiveram pouca importância como fertilizante, devido ao seu baixo conteúdo de nutrientes e sua baixa taxa de decomposição, que alcançou 30% do total num período de 6 meses, enquanto as folhas apresentaram tempo de meia vida de 19 dias.Editora UFLA2007-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/15Coffee Science - ISSN 1984-3909; Vol. 1 No. 1 (2006); p. 21-27Coffee Science; Vol. 1 Núm. 1 (2006); p. 21-27Coffee Science; v. 1 n. 1 (2006); p. 21-271984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/15/10https://coffeescience.ufla.br/index.php/Coffeescience/article/view/15/69https://coffeescience.ufla.br/index.php/Coffeescience/article/view/15/70Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessCoelho, Renato AlvesSilva, Gabriela Tavares ArantesRicci, Marta dos Santos FreireResende, Alexander Silva de2013-02-23T12:11:02Zoai:coffeescience.ufla.br:article/15Revistahttps://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:2024-05-21T19:53:25.756Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
