Abstract

The accurate estimation of reference evapotranspiration (ETo) is essential for calculating the water requirements of a crop as well as for scheduling irrigation events and for a sustainable management of water resources. In this sense, the aim of this study was to correlate the Blaney-Criddle, Hargreaves, Jensen-Haise, and Camargo methods with the Penman-Monteith method, recommended by the Food and Agriculture Organization of the United Nations (FAO) as the standard method for estimating ETo, for the city of Maués, AM, based on data obtained from the National Institute of Meteorology (INMET), from an automatic station, time series from 2009 to 2018. The standard error of estimate in relation to the standard method (EPE), the coefficients of correlation (r), determination (r²), and performance (c), and the agreement index (d) were used to compare the ETo estimation methods. Among the results obtained, it was found that all the methods evaluated overestimated ETo compared to the standard method, Penman-Monteith, in all months of the year. The Blaney-Criddle method was the best at estimating ETo for the city of Maués, AM, followed by the methods of Hargreaves, Jensen-Haise, and Camargo.
