It is not possible to crystalyze all sugar in sugarbeet. Some characteristics of sugarbeet that determine the quality of sugarbeet are non-sugar substances. Micronutrients such as environmental factors can affect the yield and quality in plants. The aim of the study was to find the effects of micronutrients (Fe, Zn, B and Mn) on quality of sugarbeet. The study was carried out during 2005-2006 at the agricultural lands of Sulduz region (most important region in terms of sugarbeet production), West Azerbayjan Province, Iran affiliated to the Sugarbeet Factory of the region using randomized complete block design with four replications. The sugar percentage and the amounts of Na, K and N were analysed by Betalyser System (Sucromat automatic Saccharometer, flame photometer and testamin photometer). Crystallized sugar percentage, alkalinity, the precentage of sugar in molasses and sugar yield were also determined. The findings showed that sugar percentage, amount of K, Na, N, alkalinity, crystallized sugar percentage, sugar yield and percentage of sugar in molasses were between 1548-15.48- 17.77%, 6.65-7.86 (meq/100 g pulp), 1.30-1.95 (meq/100 g pulp), 1.34-7.95 (meq/100 g pulp), alkalinity 3.12- 7.95, 12.32-13.81%, 77.72-79.59% and %3.25-3.95% respectively.
