This study was conducted to determine the effect of different water levels on the sugar rate, sugar yield and root yield of sugarbeet (Beta vulgaris var. saccharifera) under Kahramanmaras (Turkey) climatic conditions in the production season 1999-2000. A line source sprinkler irrigation system was used with 6 irrigation levels; I1, I2, I3, I4, I5 and I6. The sugarbeet row adjacent to the lateral was denoted the most water applied level (I1), and the most remote row from the lateral was denoted the least water applied level (I6). The plant rows between levels I1 and I6 were taken as the deficit irrigation levels in variably decreasing amounts. In the first (1999) and second (2000) years of the experiment, the total amount of irrigation water applied in a season was 1232 and 1331 mm in 1999 and 2000, respectively, while the amounts of water consumed (Et) were 1446 and 1491 mm, in 1999 and 2000, respectively. For level I1, sugar rates were 17.2 and 15.1%, sugar yields were 9870 and 9420 kg/ha, and root yields were 57 360 and 62 350 kg/ha in 1999 and 2000, respectively. Reductions in applied irrigation water increased sugar rates and reduced Et and root yield. For level I6, the amount of irrigation water applied in a season was 298 and 429 mm, Et levels were 495 and 587 mm, sugar rates were 18.9 and 18.3%, sugar yields were 1820 and 2050 kg/ha, and root yields were 9630 and 11 210 kg/ha in 1999 and 2000, respectively. Irrigation water use efficiency (IWUE) and water use efficiency (WUE) levels for I1 were 46.6 and 39.7 kg ha-1 mm-1 in 1999, and 46.8 and 418 kg ha-1 mm-1 in the 2000, respectively. Both IWUE and WUE values varied with the amount of applied irrigation water. The root yield increased as the applied irrigation water increased, and a linear relationship was found between these 2 parameters.
