The experiment was carried out in 1990, 1991, 1993 in the Rumokai Research station of the Lithuanian Institute of Agriculture. The following nitrogen norms were analysed: 0(0+0), 45(0+45), 45(45+0), 90(45+45), 90(90+0), 135(90+45), 135(135+0), 180(135+45), 180(180+0), 225(180+45). Sugar production is negatively affected by soluble non-sugar substances (soluble potassium and sodium salts, amines) that prevent crystallization of sugar. Norms of nitrogen fertilisers increased the amount of: potassium by 8.9-38.2%, sodium - 11.0-54.4%, alpha-amine N - 43.0-163.5 %, while additional application of nitrogen -45 kg ha*[-1) - resulted in the increase of: 1.0 - 7.9% potasium, 1.0-8.0 % sodium, 18.2 - 44.9 % alpha-amine N. Strong positive corelation (eta=0.99) has been established between the norms of nitrogen fertilisers and soluble non-sugar substances. Potassium, sodium and alpha-amine N negatively influence the sugar content roots (eta=-0.59). Among the 14 analysed varieties, the amount of low soluble non-sugar substances was significant in the roots of Kristall, Accord and Extra varieties. The highest yield of white sugar has been found in the varieties of Freja, Anna, Accord, Extra (7.3-7.7 t ha*[-1)).
