This study was undertaken to determine the WUE of oat (Avena sativa L.) because recent field evaluations for this crop are not available. Oat was grown on loess-derived silt loam fine-silty, mixed, mesic Typic Hapludalf) near Goettingen, West Germany, during 4 yr. Periodically, shoot and root dry matter were determined. Water use within five consecutive growth stages was evaluated by the soil water budget approach. Balanced evapotranspiration (ET), including evaporation from soil (E), water T2 - Agronomy Journal ER -
