There search presents results of the study of the influence of mineral fertilization level on they ield of winter rapeseed of DK Sensei hybrid on the dark gray podzolic soils of theWestern Forest-Steppe of Ukraine. Comparing to the control (without fertilizers), the following norms of mineral fertilizers were studied: P38K60 + N51 in fertilization (shooting), N34P48K80 + N34 in fertilization (shooting), N51P58K100 + N51 in fertilization (shooting), N68P68K120 + N68 in fertilization (shooting), N68P68K120 + N34 in fertilization (shooting) + N34 in feed (budding). It is proven that for the cultivation of winter rapeseed after winter wheat, it is advisable to apply mineral fertilizers in the norm of N68P68K120 + N34 in fertilization (shooting) + N34 in fertilization (budding). That level of mineral fertilization secured the highest yield of 35.5 centners/ha, which was by 17.3 centners/ha above the control variant. The lowesty ield of 18,2 centners/ha was obtained in the control variant without application of mineral fertilizers. With the application of P38K60 + N51in fertilization(shooting), they ield was 24.3 centners/ha, i.e. by 6,1 centners/ha or 33.2 % above the control variant.

The highest oil content of 44.0 % was obtained in the control variant, but the highest oil yield was obtainedin the variant with application of mineral fertilizers in the norm of N68P68K120 + N34 in fertilization (shooting) + N34 in fertilization (budding) andit accounted for 13.8 centners/ha, 5.8 centners/ha above the control variant. In the variant with application of mineral fertilizers in the norm of N68P68K120 + N68 in fertilization (shooting), the oil content was 38.9 %, i.e. 5.8 % above the control variant, where as they ield of oil of 12.9 centners/ha exceeded the control by 4.9 centners/ha.

Highest net operating profit (20275 UAH/ha), profitability (91.0 %) and payback of 1 UAH of costs for fertilizer application (3.0 UAH) were obtained in the variant of the experiment with application of mineral fertilizers in the norm of N68P68K120 + N34 in fertilization (shooting) + N34 in fertilizing (budding). In the control version, the net operating profit was only 6335 UAH/ha and 41 % of profitability. Payback of 1 UAH of fertilizer costs increases due to the increasing norms of mineral fertilization level .
