Actual evapotranspiration measurements of irrigated wheat, grown under the soil and climatic conditions of Viçosa, MG., were taken by means of 16 drainage-type lysimeters, and the crop evapotranspiration coefficient (K) determined in relationship to the potential evapotranspiration as obtained with USWB Class A evaporation pan, Penman and Blaney-Criddle equations.
