Resumo: Among the methods of estimating reference evapotranspiration, the Penman-Monteith-FAO is considered the most accurate, however, it requires a large number of meteorological variables, making this estimate costly due to the high cost of the agrometeorological stations. On another hand, there are some others methods that require less dada, so consequently they result in a cheaper way to get the reference evapotranspiration, a condition that must be observed when users of irrigation systems are small farmers. The objective of this study was to evaluate the performance of the methods of Hargreaves-Samani, Thornthwaite-48, modified Thornthwaite, Camargo-71, Blaney-Criddle, Jensen-Haise, Radiation FAO 24, Aerodynamic and Energy balance, in estimate the reference evapotranspiration in the area of influence of the São Francisco River Transposition. The meteorological data cover the period from 1995 to 2014. The performance of the Hargreaves-Samani and Thornthwaite modified methods were rated as "great", and as they require only air temperature data, it can be recommended as an alternative for small agricultures to estimate reference evapotranspiration in the study area.

Porém, necessita de grande número de variáveis meteorológicas, tornando essa estimativa onerosa pelo elevado custo das estações agrometeorológicas. Por outro lado, existem outros métodos que demandam menos dados, representando uma maneira menos onerosa de se estimar a evapotranspiração de referência, condição essa que deve ser observada quando os usuários de sistemas de irrigação são pequenos produtores. O objetivo deste trabalho foi avaliar o desempenho dos métodos de Hargreaves-Samani, Thornthwaite-48, Thornthwaite modificado, Camargo-71, Blaney-Criddle, Jensen-Haise, Radiação FAO 24, Aerodinâmico e Energético, na estimativa da evapotranspiração de referência na área de influência da Transposição das águas do rio São Francisco. Foram utilizados dados meteorológicos do período de 1995 a 2014. O método de Hargreaves-Samani obteve desempenho classificado como “ótimo”, sendo este desempenho consistente ao longo da área estudada. Por necessitar somente de dados de temperatura do ar, sugere-se esse método como alternativa de uso aos pequenos produtores na estimativa da evapotranspiração de referência na região estudada.Universidade Federal de Viçosa - UFV2017-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/68210.13083/reveng.v25i6.758Engineering in Agriculture; Vol. 25 No. 6 (2017); 526-539Revista Engenharia na Agricultura - REVENG; v. 25 n. 6 (2017); 526-5392175-68131414-398410.13083/reveng.v25i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/682/pdfIde, Andre KeiitiSilva, Cícero Lopes dainfo:eu-repo/semantics/openAccess2023-01-19T13:33:21Zoai:ojs.periodicos.ufv.br:article/682Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:33:21Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
