Description:
The efficient use of water resources in agriculture requires adequately quantifying the water use, i.e. ET, which represents the main consumptive use of water in agricultural production. ET represents direct response in terms of water losses from the field as a function of soil, water, and crop management and climatic conditions and is a powerful indicator of crop water productivity. Therefore, it is important to understand and accurately quantify ETc, which further can help farmers to use reliable information and tools to make better irrigation decisions. This bulletin describes the basic concept of evapotranspiration and defines the major difference between commonly used ET terms, mainly PET, ETref, and ETc. A common understanding of these terms will help to understand the fundamental ET process and to better communication among producers, extension educators, and researchers.
