We studied the effect of different fertilization dosages on the yield and some generative factors (thousand seed weight, lenght of spike, number of spiklets) of winter wheat in 2015-2016 years. The experiment carried out on the area of SZTE Tangazdaság Ltd, in three replications after alfalfa forecrop. The soil of the experiment was meadow soil. The year of 2015-2016 was favourable for winter wheat. The amount of precipitation in the vegetative period of winter wheat was higher by 92.8 mm than the average. Beside the control we applied four fertilizer treatments: N80PK30, N100PK30, N120PK0, N120PK30 kg/ha active ingredients. We processed the obtained data by single factor variant analysis. We reached the highest yield in the N80PK30 treatment, which was significantly higher compared the control. Among the examined generative factors, fertilization treatments increased significantly the length of spike and number of spiklets compared the control. Under the influence of fertilization the plant height also changed significantly.
