Resumo: This study aimed to determine the crop evapotranspiration (ETc) and crop coefficient (Kc) of fertigated sweet pepper, measured over time (15, 30, 45, 60, 75, 90 and 105 days after the transplant). The experiment was conducted on a battery of 40 drainage lysimeters, arranged in a 8 x 5 matrix, in the period October/2009 to January/2010, located in the Federal Rural University of Pernambuco (UFRPE) Campus in Recife, in a completely randomized factorial scheme 5 x 2, with four replications, being five irrigation depths (80, 90, 100, 110 and 120% of ETc) and two levels of potassium (80 and 120 kg K2O ha-1) where the experimental plot was composed of three plants in each lysimeter. The Mauchly Sphericity Test indicated multivariate variance analysis for the studied variables ETc (mm d-1) and Kc, the variables presented adjustment under quadratic effect of variation on observation times, when the irrigation depths were fixed, and descending linear adjustments under the variation of irrigation depths effect, when the times of observation were fixed in each potassium dose.

O experimento era conduzido em uma bateria de 40 lisímetros de drenagem, dispostos em uma matriz de 8 x 5, no período de outubro/2009 a janeiro/2010, localizada no campus da Universidade Federal Rural de Pernambuco (UFRPE), Recife, PE, em delineamento estatístico inteiramente casualizado e esquema fatorial 5 x 2, com quatro repetições, sendo cinco lâminas de irrigação (80, 90, 100, 110 e 120% da ETc) e duas doses de potássio (80 e 120 kg K2O ha-1), cuja parcela experimental era composta por três plantas em cada lisímetro. O Teste de Esfericidade de Mauchly indicou análise de variância multivariada para as variáveis estudadas ETc (mm d-1) e Kc, e as mesmas apresentaram ajustes quadrático sob efeito da variação das épocas de observação, quando se fixa as lâminas de irrigação, e ajustes linear decrescente sob efeito da variação das lâminas de irrigação, quando se fixa as épocas de observação, em cada dose de potássio.Departamento de Tecnologia Rural UFRPE, Rua Dom Manoel de Medeiros, s/n, Dois Irmãos, 52.171-900, Recife/PEFaculdade de Ciências Agronômicas de Botucatu UNESP, Rua José Barbosa de Barros, 1780, 18.610-307, Botucatu/SPFaculdade de Ciências Agronômicas de Botucatu UNESP, Rua José Barbosa de Barros, 1780, 18.610-307, Botucatu/SPUniversidade Federal Rural de Pernambuco (UFRPE)Universidade Estadual Paulista (Unesp)Albuquerque, Francimar da SilvaSilva, Ênio Farias de França EAlbuquerque Filho, João Audifax Cézar deLima, Géssica Silva [UNESP]2014-05-27T11:27:22Z2014-05-27T11:27:22Z2012-12-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article481-493application/pdfhttp://irriga.fca.unesp.br/index.php/irriga/article/view/399Irriga, v. 17, n. 4, p. 481-493, 2012.1413-78951808-3765http://hdl.handle.net/11449/739492-s2.0-848722509622-s2.0-84872250962.pdfScopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengporIrriga0,283info:eu-repo/semantics/openAccess2023-11-27T06:12:40Zoai:repositorio.unesp.br:11449/73949Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T18:50:43.250716Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
