Due to recent climate change, various studies are needed to respond to water shortage in the agricultural sector. One of the important factors for efficient water management is the quantification of evapotranspiration. In this study, water balances such as evapotranspiration and precipitation during growth of forage barley (Hordeum vulgare L.), a winter crop, were compared and analyzed using a weighable lysimeter, and crop coefficients and optimal water requirements for each growth stage were presented. Forage barley was cultivated repeatedly for three years in two soils with different soil textures. As a result of analyzing the water balance, there was no difference in the total inflow between two soil textures. The total outflow tended to be higher in the sandy loam soil, because the evapotranspiration was higher in the sandy loam soil which is better for crop growth. The crop coefficients by growth stage were 0.80, 1.00, 1.00, 1.30, and 1.17, respectively. As a result of estimating the optimal water requirement during the three-year cultivation period and comparing it with normal years, it was 15%, 7%, and 1% higher than normal years due to the low cumulative precipitation, and the water requirements were slightly higher than normal years. Accurate water balance evaluation and development of national factors in Korea using weighable lysimeter are expected to contribute to the estimation of the water management for upland crops in the future.
