In the years of 1998-2003 a field experiment was performed. The aim of this experiment was to determine the influence of different levels of nitrogen (0, 80, 120, 160 kg/ha) on the grain yield and the technological parameters quality of two winter wheat cultivars (Begra, Korweta). On the basis of the results it was found out that winter wheat - cultivar Korweta was characterized by a higher grain yield in comparison to cultivar Begra. Begra was characterized by more profitable values of technological parameters (sedimentation ratio, bread volume, falling number and gluten weakening) in relation to cultivar Korweta. After the use of nitrogen in the dose of 120 kg/ha average essential increase of grain yield of winter wheat was found. Diverse fertilization with nitrogen, in all practical doses, determined the average protein content in grain in the studied cultivars of winter wheat. Values of the investigated technological parameters of winter wheat cultivars showed height tendencies in all ranges of nitrogen doses. It was shown that the optimum nitrogen doses having influence on the most important quality parameters, i.e. gluten content, sedimentation ratio and bread volume, are as follows: 160 kg N/ha, 80 kg N/ha and 120 kg N/ha
