Analyses of spring barley evapotranspiration rates based on gradient measurements and dual crop coefficient model

Popis výsledku v původním jazyce

The yield of agricultural crops depends on water availability to a great extent. According some projections, the likelihood of stress caused by drought is increasing in future climates expected for the Central Europe. Therefore, in order to manage agro-ecosystems properly, it is necessary to know water demand of particular crops as precisely as possible. Evapotranspiration (ET) is the main part of water balance which takes the water from agro-ecosystems away. The ET consists of evaporation from the soil(E) and transpiration (T) through the stomata of plants. In this study, we investigated ET of spring barley 1-ha field (Domanínek, Czech Republic) measured by Bowen ratio/energy balance method during growing period 2013 (May 8 to July 31). Special focuswas dedicated to comparison of barley ET with the reference grass ETo calculated according FAO-56 model, i.e. the determination of barley crop coefficient (Kc). This crop coefficient was subsequently separated into soil evaporation (Ke)
