The grain yield and technological quality of two winter wheat cultivars Sukces and Tonacja depending on nitrogen fertilization doses and way of N application were determined and described in the field experiment conducted in Puławy Experimental Station in 2004-2006. Three nitrogen fertilization doses 0, 120, 180 kg N·ha^-1 and two ways of nitrogen application (two times and tree times) were applied in this experiment. The biggest grain yield was obtained with nitrogen fertilization at a dose of 180 kg N·ha^-1 and 120 kg N·ha^-1 applied in two doses during growing period. Nitrogen fertilization applied at a dose of 120 kg N·ha^-1 three times during the growing period of winter wheat caused an increase in protein and gluten content and sedimentation value compared with two times. The way of nitrogen fertilization applied at a dose of 180 kg N·ha^-1 had no significant influence on grain quality.
