The aim of this study was to determine the evapotranspiration of wheat, and the methods for calculating potential evapotranspiration and water needs of wheat for the area of Nis. On the experimental field produced wheat yield of 4.25 t ha-1. The total measured water consumption evapotranspiration was 319 mm. Calculated the coefficient of utilization of water (WUE) of wheat of 13.3 kg ha-1 mm-1. Linear regression analysis between measured ET and calculated ETPo determined highly significant correlations. Cilj rada je bio da se utvrdi evapotranspiracija pšenice, a metodama za obračun potencijalne evapotranspiracije i potrebe za vodom pšenice za rejon Niša. Na oglednom polju dobijen je prinos zrna pšenice od 4,25 t ha-1. Ukupan izmeren utrošak vode na evapotranspiraciju bio je 319 mm. Obračunat je koeficijent iskorišćenosti vode (WUE) pšenice od 13,3 kg ha-1 mm-1. Analizom linearne regresije između izmerene ET i obračunate ETPo utvrđena je visoko signifikantna korelacija.
