Field studies were conducted in Erzurum, Turkey, during the 2003 and 2004 cropping seasons, to investigate the effect of deficit irrigation (0, 20, 40, 60, 80 and 100% no irrigation) on the root, leaf and total sugar yield and water use efficiency of sugarbeet under semiarid and cool season climatic conditions. Deficit irrigation treatments significantly decreased root, leaf and total sugar yield compared to the unstressed (well-irrigated) control. Root, leaf and total sugar yield of the control were 38.35, 12.32 and 7.34 t/ha compared to 19.96, 5.10 and 3.84 t/ha in the non-irrigated treatment, respectively. A linear relationship was established between evapotranspiration and root yield. Sugar content in beet was between 18.70 and 19.30%, but there were no statistically significant difference between treatments. The highest water use efficiency was obtained with the non-irrigated treatment (91.84 kg/ha/mm). The yield response factor on root yield was 0.95.
