Resumo: | The mineral nutrition of the coffee tree is very important for its yield, and several places that previously were considered unfit for the cultivation, today exhibit highly productive crops, where soil fertility correction, over time, combined with proper mineral nutrition, are some of the main factors for this success. The aim of this research was to evaluate four new coffee cultivars at initial growth under different doses of nitrogen, phosphorus and potassium. The trial was carried out at the Experimental Farm of EPAMIG, in São Sebastião do Paraíso, MG, Brazil, on February 2012. Four cultivars were used in twelve treatments (factorial scheme, four cultivars, three nutrients and four doses), under randomized block design. Joint analysis of the data was made. The traits evaluated were: height, diameter of the stem, growth of the first plagiotropic branch, number of plagiotropic branches, chlorophyll index and soil and leaf analyzes. It was concluded that in the initial chemical conditions of the soil used in the experiment, fertilizations with N, P and K, both in cover fertilization and first-year fertilization, can be reduced in up to 50% in coffee plantations of the cultivars Pau Brasil MG1, Paraíso MG H419-1 and Topázio MG 1190. |

Observa-se que diferentes cultivares de diversas espécies exigem níveis de nutrição diferenciados, para expressarem seu máximo potencial produtivo sob determinadas condições de cultivo. Objetivou-se, neste trabalho, avaliar quatro novas cultivares de cafeeiro quanto ao seu crescimento inicial, sob diferentes doses de nitrogênio, fósforo e potássio. O experimento foi instalado na Fazenda Experimental da EPAMIG, em São Sebastião do Paraíso – MG, em fevereiro de 2012. Foram utilizados quatro cultivares de cafeeiro que foram submetidos a doze tratamentos (esquema fatorial, sendo quatro cultivares, três nutrientes e quatro doses), contendo três repetições, sob delineamento em blocos casualizados. Foi feita uma análise conjunta dos dados. As características avaliadas foram: altura, diâmetro do colo, crescimento do primeiro ramo plagiotrópico, número de ramos plagiotrópicos, índice de clorofila e foram feitas análises de solo e foliares. Concluiu-se que nas condições químicas iniciais do solo utilizado no experimento podem-se reduzir em até 50% as adubações com N, P e K, tanto em adubação de cobertura como para adubação de primeiro ano, em lavouras cafeeiras plantadas com as cultivares Pau Brasil MG1, Paraíso MG H419-1 e Topázio MG 1190.Editora UFLA2017-11-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfimage/jpegimage/jpegimage/jpegimage/jpegapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370Coffee Science - ISSN 1984-3909; Vol. 12 No. 4 (2017); 552 - 561Coffee Science; Vol. 12 Núm. 4 (2017); 552 - 561Coffee Science; v. 12 n. 4 (2017); 552 - 5611984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/pdf_1370https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1822https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1823https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1824https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1825https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1826https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1370/1827Copyright (c) 2017 Coffee Scienceinfo:eu-repo/semantics/openAccessVilela, Diego JúniorCarvalho, Gladyston RodriguesBotelho, Cesar EliasCarvalho, Alex MendonçaPraxedes, Marina AngélicoSantos, Milena ChristyFernandes, Fernando Costa2017-11-28T15:57:51Zoai:coffeescience.ufla.br:article/1370Revistahttps://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:2024-05-21T19:54:03.641597Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
