The effect of various forms of nitrogen fertilizers, namely ammonium nitrate, urea and ammonium sulfate on the oil content in varieties and hybrids of spring rape in conditions of Right Bank Forest-steppe of Ukraine is considered in the paper. Spring rape, namely its seeds, is a source of cheap vegetable oils with high indexes of food quality. In order to ensure the yield of spring rape seeds with high oil content, it is necessary to observe the optimal ratio of intensification of cultivation elements, including the application different forms of nitrogen fertilizers. For solving issued challenges during 2015-2017, we conducted field research in the field of stationary field crop rotation of Plant Frowing Department at the PE NULES "Agronomic Experimental Station" (Vasylkivsky District, Kyiv Region, Pshenichne Village). Soil - the typical black (deep) low-humus, medium loamy by the texture. The total area of counting lot – is 25 m2.  Repetition of the experiment is quadruple. This study made it possible to establish that the highest oil content (gain to control 2.6 - 3.4%) in the rape seeds of both varieties and hybrids were at variant with ammonium sulfate introduction. In the context of varieties and hybrids, hybrid Jerome (46.8%) was better by the oil content.
