Resumo: | Spending on labor may represent more than 50% of the total production cost of Conilon coffee, and pruning and thinning responsible for most of these costs, behind only the harvest expenses. Some growth phytoregulator auxin group associated with potassium (K2O) can reduce bud emission. It is aimed to work verify the effect of naphthalene acetic acid (NAA) associated with potassium fertilization on budding Conilon coffee. The experiment was carried out from June 2014 to December 2015 in adult crop of non-irrigated Conilon coffee, the cultivate “G35-Verdebrás” located at the Federal Institute of the Holy Spirit - Campus Santa Teresa. The randomized blocks were used with the 5x4 factorial arrangement between levels of NAA and levels of K2O, respectively. They were applied five doses of NAA (0, 50, 100, 250 and 500 mg L-1) and four of K2O in the fertilizer (60, 120, 240 and 480 kg ha-1). It was observed that the application of NAA influences the emission of shoots for favoring apical dominance of the plants. K2O levels applied interfere with the action of NAA, and the application of high doses of nutrient can inhibit the action of this phytoregulator. The application of 344 mg L-1 NAA associated with fertilization of 120 kg ha-1 of K2O, reduced the number of shoots per plant without interfering with the productivity and development of the remaining shoots. |

Alguns fitorreguladores de crescimento do grupo das auxinas associados ao potássio (K2O) podem reduzir a emissão de brotos. Objetivaram-se com o trabalho verificar o efeito do ácido naftalenoacético (ANA) associado à adubação potássica na brotação de café Conilon. O experimento foi realizado de junho de 2014 a dezembro de 2015, em lavoura adulta de café Conilon não irrigada, da cultivar “G35-Verdebrás”, localizada no Instituto Federal do Espírito Santo – Campus Santa Teresa. Utilizaram-se o delineamento em blocos casualizados, com o arranjo fatorial 5x4 entre níveis de ANA e níveis de K2O, respectivamente. Foram empregadas cinco doses de ANA (0, 50, 100, 250 e 500 mg L-1), e quatro de K2O na adubação, (60, 120, 240 e 480 kg ha-1). Observou-se que a aplicação de ANA influencia a emissão de brotos por favorecer a dominância apical das plantas. Os níveis aplicados de K2O interferem na ação do ANA, sendo que a aplicação de dosagens elevadas do nutriente pode inibir a ação deste fitorregulador. A aplicação de 344 mg L-1 de ANA associada à adubação de 120 Kg ha-1 de K2O reduziu o número de brotos por planta sem interferir na produtividade e desenvolvimento das brotações remanescentes.Editora UFLA2017-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenttext/rtfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279Coffee Science - ISSN 1984-3909; Vol. 12 No. 2 (2017); 282-289Coffee Science; Vol. 12 Núm. 2 (2017); 282-289Coffee Science; v. 12 n. 2 (2017); 282-2891984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279/pdf_1279_2https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279/1752https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279/1753https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279/1754https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1279/1755Copyright (c) 2017 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessForça Baroni, DaniloSilva dos Reis, LuciléaCorona Baitelle, DiegoMoraes Vieira, KeziaCelestino Meireles, RobsonVerdin Filho, Abraão CarlosRamalho Haddade, Ismail2017-06-06T13:35:28Zoai:coffeescience.ufla.br:article/1279Revistahttps://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:2024-05-21T19:54:01.598672Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
