Resumo: | The objective of this work was to evaluate the effect of N and K fertilization on the yield and production bienniality of dense coffee plantations, in a long‑term study. Two experiments were evaluated in the Zona da Mata region of Minas Gerais, Brazil, under a randomized complete block design, split‑plotted in time. In the first experiment, carried out with 1.5x0.7 m spacing (9,523 plants per hectare), the effects of seven doses of N + K2O in the proportion of 1:1 were evaluated (0, 200, 400, 600, 800, 1,000, and 1,200 kg ha‑1 per year) during eight crop seasons (2001/2002 to 2008/2009). Since the fertilizer had 1:1 proportion, in order to obtain the dose for each nutrient (N or K2O), the total dose must be divided by two. The second experiment was done with 2.5x0.6 spacing (6,666 plants per hectare), under a factorial arrangement, with five doses of N (0, 150, 300, 450, and 600 kg ha‑1 per year) and five doses of K2O (0, 150, 300, 450, and 600 kg ha‑1 per year), during six crop seasons (2005/2006 to 2010/2011). The doses related to the maximum yield of processed coffee ranged from 424 to 560 kg ha‑1, for N, and from 21 to 338 kg ha‑1, for K2O. Nitrogen fertilization reduces the effect of production bienniality of coffee plants, and K2O fertilization, in years of low productivity, promotes yield recovery of coffee plants in the next year. |

Foram avaliados dois experimentos, na região da Zona da Mata de Minas Gerais, conduzidos em blocos ao acaso, com parcelas subdivididas no tempo. No primeiro experimento, realizado no espaçamento de 1,5x0,7 m (9.523 plantas por hectare), foram avaliados os efeitos de sete doses de N + K2O na proporção 1:1 (0, 200, 400, 600, 800, 1.000 e 1.200 kg ha‑1 por ano), durante oito safras (2001/2002 a 2008/2009). Como o fertilizante utilizado tinha proporção 1:1, para obter a dose utilizada de cada elemento (N ou K2O), deve-se dividir a dose total por dois. O segundo experimento foi conduzido no espaçamento de 2,5x0,6 m (6.666 plantas por hectare), em arranjo fatorial, com cinco doses de N (0, 150, 300, 450 e 600 kg ha‑1 por ano) e cinco doses de K2O (0, 150, 300, 450 e 600 kg ha‑1 por ano), durante seis safras (2005/2006 a 2010/2011). As doses associadas à máxima produtividade de café beneficiado variaram de 424 a 560 kg ha‑1, para N, e de 21 a 338 kg ha‑1, para K2O. A adubação com N reduz os efeitos da bienalidade da produção do cafeeiro, e a adubação com K, em anos de baixa produtividade, favorece a recuperação da produtividade do cafeeiro no ano seguinte.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraValadares, Samuel VasconcelosNeves, Júlio César LimaRosa, Gustavo Nogueira Guedes PereiraMartinez, Hermínia Emília PrietoAlvarez Venegas, Víctor HugoLima, Paulo César de2013-06-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13235Pesquisa Agropecuaria Brasileira; v.48, n.3, mar. 2013; 296-303Pesquisa Agropecuária Brasileira; v.48, n.3, mar. 2013; 296-3031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13235/11167https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13235/9001info:eu-repo/semantics/openAccess2013-06-06T21:18:08Zoai:ojs.seer.sct.embrapa.br:article/13235Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-06-06T21:18:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
