The research was based on a three-year field experiment conducted in 2018-2021, at the Zawady Agricultural Experimental Station (52o03'N and 22o33'E), Siedlce, in the climatic and soil conditions of north-eastern Poland. The experiment was set up in a split-plot design with three replications.  The research factors were: I - three morphotypes of winter oilseed rape: population (Chrobry), restored hybrid morphotype with the traditional type of growth (PT 271), restored hybrid morphotype with the semi-dwarf growth type (PX 113). II - four ways to use growth stimulants: object 1 - control object - without the use of stimulators, object 2 - organic preparation containing microorganisms as well as micro- and macro-elements (UGmax), object 3 - biostimulant containing 13.0% P₂0₅ and 5.0% K₂O (Rooter), object 4 - biostimulant containing silicon (Optysil). The types of applied preparations significantly influenced the utility value of seeds by increasing or decreasing the concentration of glucosinolates. A significant reduction of harmful sulphur compounds compared to the control variant was noted only as a result of the use of a plant stimulator containing silicon. After the application of the stimulator containing phosphorus and potassium, an increase in the concentration of these compounds in seeds was noted. The thresholds of these compounds were not exceeded. In all the years of the research, after the application of the organic preparation Ugmax, the same content of these compounds was demonstrated as in the control object. The population morphotype was characterized by the lowest concentration of glucosinolates, and the highest one was determined in the restored hybrid with the traditional type of growth. The climatic conditions influenced the concentration of these compounds in the examined morphotypes.
