Resumo Inglês:

The study aims to estimate the reference evapotranspiration (ET0) monthly to the municipality of São Miguel do Iguaçu - PR, by the method of Hargreaves and Samani (1985). Values (ET0) are needed in the management of irrigated agriculture, have several models in the literature to estimate, but farmers advocate methods simpler and less laborious. We used historical data of average monthly air temperature and rain during the period 1983 to 1997, from a weather station of IAPAR located at latitude 25 º 20'53''S, 54 º 14'16''W longitude and altitude 307m above sea level, in São Miguel do Iguacu, Paraná State. The data were processed with the aid of a spreadsheet to estimate evapotranspiration. ET0 values range from 63 mm to 176 mm, and between the months April to September had the lowest values of ET0 caused by thermal restriction in the region, while the months from October to March have the highest values of ET0.
