Resumo: | In the face of climatic adversities associated with water lacking for irrigation, crop cultivation in greenhouses in Brazil has increased significantly, thereby demanding research that makes it possible to estimate crop water demand when grown in these environments. Therefore, the objective of this study was to evaluate the performance of Irrigameters to estimate the evapotranspiration of cowpea grown in protected environment. The experiment was conducted in the experimental area of the State University of Southwest of Bahia (UESB) under protected environment and the cowpea variety used was BRS Guariba. For this study, two Irrigameters were installed for the direct estimation of the daily crop evapotranspiration. Likewise, with the use of an automatic weather, the meteorological data were collected and the crop evapotranspiration (ETc) was estimated using the Kc values recommended for different phases of the crop. The data collected by the Irrigameter were compared with the data estimated by the Penman-Monteith method, as well as with Radiation and Blaney Criddle methods at one-, two- and three-day intervals. The results show that all the methods were efficient and accurate at estimating ETc at all studied intervals. |

Assim sendo, objetivou-se avaliar o desempenho do Irrigâmetro para estimativa da evapotranspiração da cultura do feijão caupi em ambiente protegido. A pesquisa foi conduzida na área experimental da Universidade Estadual do Sudoeste da Bahia (UESB), em ambiente protegido e a variedade do feijão caupi utilizada foi a BRS Guariba. Para este estudo instalaram-se dois Irrigâmetros para estimativa direta da evapotranspiração diária da cultura. Da mesma forma, com o uso de uma estação meteorológica automática, coletaram-se os dados meteorológicos e estimou-se a evapotranspiração da cultura (ETc), usando os valores de Kc recomendados para as diversas fases da cultura. Os dados obtidos no Irrigâmetro foram comparados com os dados obtidos pelo método de Penman-Monteith, fazendo-se o mesmo para o método da Radiação e Blaney Criddle, em intervalos de tempo um, dois e três dias. Os resultados mostram que todos os métodos foram eficientes e precisos na estimativa da ETc, em todos os intervalos de tempo estudados.Universidade Federal Rural do Semi-Árido2019-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/795510.1590/1983-21252019v32n322rcREVISTA CAATINGA; Vol. 32 No. 3 (2019); 778-785Revista Caatinga; v. 32 n. 3 (2019); 778-7851983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7955/10063Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessGonçalves, Lorena JúlioTaglieferre, CristianoCastro Filho, Manoel Nelson deGuimarães, Diogo Ulisses GomesRocha, Felizardo Adenilson2023-07-20T17:39:43Zoai:ojs.periodicos.ufersa.edu.br:article/7955Revistahttps://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:2024-04-29T09:46:37.471317Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
