Carried out split-plot trials in four runs, during with two variable factors were examined: sulphur rates at 0,30,60 and 90 kg/ha in a form of potassium sulphate and winter oilseed rape cvs: Californium, ES Saphir and Titan. The plant material was collected twice (in autumn and in spring). Increasing rates of sulphur resulted in an increase in the total sulphur and sulphate in upper leaves, but they did not influence the nitrogen content. Chemical composition of seeds and rapeseed meal was not correlated with sulphur fertilization. Increased sulphur fertilization contributed to a higher seed yield and that of rapeseed meal, and higher values of UFL and UFV in seeds and rapeseed meal. The highest seed and rapeseed meal yield was observed with cvs: ES Saphir followed by Titan and Californium
