Abstract:  Among upmost important effects of climatic variability and change are the related variations in type, amount and timing of precipitation at global or regional scales. This aspect causes different effects from the agricultural point of view.  Among these effects the drought phenomenon comes to the forefront.  Efforts on eliminating the agricultural drought problem are mainly made by irrigation.  That’s why the upmost important portion of available water is consumed by agricultural irrigation, globally. Concordantly, the evapotranspiration plays a crucial role on determination of the irrigation water requirement for agriculture and planning the related systems. Usage of the methods on direct measurement of actual evapotranspiration by global means, however; is quite scarce.  In this study, the Bowen Ratio Energy Balance and micrometeorological Eddy Covariance Methods, which are widely in use for the measurement of actual evapotranspiration, have been used within the 2009-2010 wheat growing season in Kırklareli. In conclusion, a comparative evaluation of these approaches was done for the advantages and disadvantages by means of their determination abilities of actual evapotranspiration.
