The aim is an assessment of the actual evapotranspiration of plants by using climate data in Nakhon Ratchasima with the R in the hydrological modeling function of Abtew and Morton CRAE formulation. There are using meteorological data from 2012 - 2016 at Nakhon Ratchasima station. The case analysis shows the results of evapotranspiration are the potential of evaporation of plants each year. Abtew analysis gave higher monthly evapotranspiration results during the dry season than Morton CRAE, but with Abtew formulation gave lower monthly evapotranspiration results during the rainy season than that of the method. The results are 2 ways to use evapotranspiration for water management, which is to analyze the amount of evapotranspiration for use in irrigation systems in order to water for plants should use the form of Abtew form because it can be seen that during the dry season and the plant has a high evapotranspiration value. Form Morton CRAE should be used to assess the potential water use of plants that can be seen in the dry season, the evaporation of plants is also less because in the surrounding environment there isn’t water and has little moisture causing plants to use less water.
