Field experimental results on evapotranspiration of spring barley at Gross-Enzersdorf, BOKU University, Vienna

A field experiment was carried to determine the components of evapotranspiration (ET) of spring barley under rainfed conditions. The study was carried out at the experimental station of University of Natural Resources and Life Sciences, Vienna (BOKU) in Groß- Enzersdorf, outside Vienna. The study showed that daily ET of spring barley calculated using FAO-Penman-Monteith method was comparable with lysimeter measured values during the different growing stages. Similarly, daily evaporation and transpiration determined using isotopic technique (Keeling plot method) corresponded well with those simulated using AquaCrop model. A novel method to take standardized canopy cover photos on a camera with a stand was developed as part of this study. (author)
