This paper analyses the variability of evapotranspiration for different types of plant: grass, peas, corn, and apple trees. It uses data measured at three evapometric stations in Romania and simulated by the CropWat model. The results show differences between the evapotranspiration of different plant types, and the importance of the foliar surface and of a plant’s development stage. Thus, during the growing season (April/May – September), corn and apple tree lose 400 – 500 mm of water by evapotranspiration, peas 360 – 400 mm and grass 310 – 330 mm. The highest water volumes are lost in June – July, months with intense vegetation activity. Evapotranspiration is 100 mm inferior on bare soil than on soil covered by apple trees. These studies will be useful for agricultural purposes in order to estimate the water needs of crops and develop irrigation plans.
Key words: evapotranspiration / experimental evapometric stations / CropWat model / Romania
