Abstract

This study focuses on estimating actual evapotranspiration for various agricul-
tural crops under dry conditions. By combining measurements and hydrological
models, the research aims to bridge the gap between direct measurements and
modelling approaches. Six crop types, including perennial rye grass, red clover,
ribwort plantain, chicory, maize, and sorghum, were examined in a field experi-
ment. Results revealed that actual evapotranspiration was significantly reduced
during dry periods, particularly in the summer of 2022. Moreover, differences
in water use efficiency (WUE) between C3 and C4 plants and drought-resistant
crops were observed. The proposed method offers a tool to generate evapo-
transpiration data for different crops, aiding in informed decision-making for
water management and sustainable crop selection.
