Resumo: Little is known about the management of high-yield clonal Coffea canephora in the Amazonian Region, mainly for nutritional aspects and cultivation system efficiency. This study aimed to evaluate the influence of different nitrogen and potassium fertilization rates on coffee grain yield and fertilizer use efficiency of C. canephora trees. An experiment was performed at an experimental field of the Embrapa Rondônia in Porto Velho (RO), Brazil. It was carried out in a split-plot scheme with six doses of 20-00-20 NPK formulation (0; 250; 500; 1,000; 2,000; and 3,000 kg ha-1) and three years of evaluation (2014, 2015, and 2016). An interaction between fertilizer dose and crop year was observed. Fertilizer doses showed an exponential behavior, with maximum yields of 51, 114, and 79 bags ha-1 at 3,000 kg ha-1 in the crop years of 2014, 2015, and 2016, respectively. Such a behavior impacted average and accumulated yields in the three harvest seasons. As for crop year effect within each fertilizer dose, the highest yield was reached in the second harvest after pruning for renewal of orthotropic stems. Moreover, fertilizer use efficiency by plants decreased exponentially, with the highest value at the lowest dose. Increasing doses of 20-00-20 formulation promoted an exponential increase in grain yield but decreased its use efficiency by C. canephora plants. This management also stimulated a strong biannual production.

Assim, o objetivo neste estudo foi avaliar a influência de doses de adubação nitrogenada e potássica sobre a eficiência do uso de fertilizantes e a produtividade em cafeeiros C. canephora.  O experimento foi conduzido no campo experimental da EMBRAPA Rondônia em Porto Velho - RO, em esquema de parcelas subdivididas no tempo, composto pela combinação de 6 doses de fertilizantes (0; 250; 500; 1.000; 2.000 e 3.000 kg ha-¹ do formulado 20-00-20) e 3 anos de avaliação (safras 2014, 2015 e 2016). Foi observado interação entre os fatores doses e anos de avaliação.  Para efeito de dose dentro de cada safra foi evidenciado comportamento exponencial, com produções máximas de 51, 114 e 79 sacas ha-¹ na dose de 3.000 kg do formulado em todas as safras avaliadas, respectivamente. Este comportamento foi refletido nas produtividades média e acumulada das três safras. Quanto ao efeito de safras dentro de cada dose, a safra do ano de 2015 apresentou maior produtividade. Para a eficiência do uso dos fertilizantes, o comportamento foi exponencial decrescente apresentando maior eficiência na menor dose.  O aumento das doses do formulado promove incremento exponencial da produtividade e decréscimo na eficiência do uso de fertilizantes por cafeeiros Coffea canephora, e sob esse manejo ocorre forte bienalidade de produção.    Universidade Federal Rural do Semi-Árido2021-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/944810.1590/1983-21252021v34n225rcREVISTA CAATINGA; Vol. 34 No. 2 (2021); 486-493Revista Caatinga; v. 34 n. 2 (2021); 486-4931983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9448/10630Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessTorres, Josemar DávilaEspindula, Marcelo CuritibaAraújo, Larissa Fatarelli Bento deMarcolan, Alaerto LuizRocha, Rodrigo Barros2023-07-19T12:18:21Zoai:ojs.periodicos.ufersa.edu.br:article/9448Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:49.672720Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
