The present field experiment and lab investigations analysed the effect of nitrogen fertilisation at the rates of 0, 80, 160 and 240 kgˇha-1 on the technological root value of the following cultivars ‘Action’, ‘Amelia’, ‘Atair’, ‘Cordelia’, ‘Dojana’, ‘Evita’, ‘Fontana’, ‘Gala’, ‘Hanna’, ‘Jupiter’, ‘Nilla’, ‘PN Mono 4’ ‘Sofie’ and ‘Sonja’. 80 and 160 kgˇha-1 of N resulted in a significant increase in the single root weight, root yield and the biological sugar yield. Technological sugar yield justified only the application of 80 kgˇha-1 of N. The increase in the technological sugar yield at 160 kgˇha-1 of N was insignificant, while an increase in N rate up to 240 kgˇha-1 made the yield correspond to that obtained for 80 kgˇha-1 of N. With rates increasing by further 80 kgˇha-1 of N, there were observed increases in the contents of alpha-amino N, sodium and potassium and decreased content of sucrose.
