Effects of different doses of nitrogen fertilizer on yield and technological quality of irrigated sugarbeet were studied at Rimski Sancevi Experimental Field, near Novi Sad (Serbia), in the 2004-2006 period. The three hybrids tested, Sara, Lara, and Drena, had been developed at Institute of Field and Vegetable Crops, Novi Sad (Serbia). The conventional production technology was applied, but adapted to irrigation conditions. The following nitrogen variants were tested: 90, 120, 150 and 180 kg/ha. The obtained yields of sugar and sugar contents in sugarbeet roots showed that the N doses of 120 and 150 kg/ha were most suitable for irrigated sugarbeets, while 90 kg/ha was the optimum dose for rainfed sugarbeets grown on chernozem and similar soils. Irrigation practice positively affected the yields of roots and sugar in spite of rainfall levels which were above the average values for sugarbeet growing season.
