The Effects of Different Nitrogen Rates on Root Yield and Quality of N and NZ Type Sugar Beet Varieties

This research was conducted to determine the effects of different nitrogen fertilizer rates (0, 60, 120, 180, 240 and 300 kg ha-1) on root yield and quality of N (Normal) type Esperenza and NZ (between Normal and Zucker = Sweet) type Isella sugar beet cultivars in The Agricultural Research and Application Center of Uludag University Faculty of Agriculture in 2010 and 2011. As a result of the research, the highest root yield values obtained from 240 and 300 kg ha-1 nitrogen rates. Also, the highest sugar content was taken from 0 kg ha-1 control dose. But, the highest sugar yields per unit area obtained from 180, 240 and 300 kg ha-1 nitrogen applications. In terms of sugar yield there were not found statistically important differences between N and NZ type sugar beet varieties.
