The article presents statistical and calculated indicators on the volumes of oilseeds cultivation,  the  effect  of mineral  fertilization  of soils during the cultivation of oilseeds on the intensity of the intake of heavy metals in them is investigated. An analysis of the cultivation of oilseeds in the Vinnytsia region showed that their total sown area as of 2021 was 351.5 thousand/ ha, of which 81.6% - sunflower, 17.7% - winter rape and 0.6% - spring rapeseed. The sown area and production volumes of sunflower seeds in the Vinnitsa region for all categories of farms amounted to 300.8 thousand/ha and 10,053.4 thousand/centner, respectively. Under the conditions of enterprises, the sown area under sunflower was 95.4%, and the volume of production - 96.4%, while in the households of the population these indicators were in the range of 4.5% and 3.6%. The sown area and production volumes of winter rapeseed seeds in the Vinnitsa region amounted to 62.8 thousand/ha and 2103.3 thousand/centner, respectively. In terms of enterprises, the area for growing sunflower was 99.2%, and in households - 0.8%, production volumes, respectively - 99.4% and 0.6%. Spring rape under the conditions of enterprises occupied 87.5% of the area, and in the conditions of households - 12.5%. The volume of production of seeds of spring rape in the conditions of enterprises amounted to 92.6%, in households - 7.3%. It was found that the highest amount of lead and cadmium entering the soil was observed during the cultivation of winter rapeseed. So, when growing winter rapeseed with mineral fertilizers, more lead and cadmium get into the soil 2.0 times and 2.4 times, respectively, compared to sunflower. When growing spring rapeseed in soils with mineral fertilizers, 1.7 times less lead and 1.75 times less lead and cadmium, compared to winter rape, get into the soil.
