USE OF IRRIGAMETER TO ESTIMATE REFERENCE EVAPOTRANSPIRATION RATE BASED ON THE CONSTANT WATER TABLE LYSIMETER METHOD

This work was carried out to evaluate the performance of an irrigameter to estimate the reference evapotranspiration rate (ET0) and compare it with the methods of FAO-Penman-Monteith, FAO-Modified Penman, FAO-Radiation, Hargreaves-Samani and Class A pan evaporation rate, relative to the constant wat...

The ET0 data obtained after one, three, five and seven days, with the use of the irrigometer were compared with the measured values of the constant water table lysimeter, operating with the modified irrigometer. The irrigameter results were satisfactory to estimate ET0 in all time intervals studied, and similar to the method of Modified Penman – FAO 24. It was concluded that the irrigameter is reliable and can be used for irrigation water management, with the advantages of relatively low cost, highly practical and without involving complex calculations.

Os dados de evapotranspiração de referência (ET0), obtidos com o Irrigâmetro e com os demais métodos, foram comparados com os valores medidos no lisímetro de lençol freático constante, operando com Irrigâmetro modificado, em intervalos de um, três, cinco e sete dias. Os resultados mostraram que o Irrigâmetro apresentou desempenho satisfatório para estimar a ET0, em todos os intervalos de tempo estudados, com comportamento semelhante ao das estimativas proporcionadas pelo método de FAO-Penman Modificado. Assim, o Irrigâmetro pode ser utilizado para o manejo da água na agricultura irrigada, com as vantagens adicionais de custo relativamente baixo, alta praticidade e não envolver cálculos. Os demais métodos estudados superestimaram os valores da ET0, obtidos pelo método do lisímetro de lençol freático constante, tendo o Tanque Classe A apresentado comportamento contrário.Universidade Federal de Viçosa - UFV2011-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/19110.13083/reveng.v19i2.209Engineering in Agriculture; Vol. 19 No. 2 (2011); 152-163Revista Engenharia na Agricultura - REVENG; v. 19 n. 2 (2011); 152-1632175-68131414-398410.13083/reveng.v19i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/191/155info:eu-repo/semantics/openAccessTagliaferre, CristianoOliveira, Rubnes Alves deSediyama, Gilberto ChohakuCecon, Paulo RobertoMateran, Franklin José Valbuena2023-01-19T12:50:32Zoai:ojs.periodicos.ufv.br:article/191Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:50:32Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
