Spring rape is a high-marginal crop that can be used in different areas of the nationaleconomy. Despite this, the area used for sowing this crop in the Russian Federation is still small,and the quality of its seeds does not always meet the standards. The purpose of the research is toidentify the most effective doses of mineral fertilizers that allow obtaining the planned harvest ofhigh-quality spring rape seeds in the southern forest-steppe of the Republic of Bashkortostan. Thepaper presents the results of triennial field researches (2016–2018) on the effect of mineralfertilizers on some indicators of the quality of spring rape seeds of the Iubileynyi variety. Theresearch was carried out in the educational and scientific center of Bashkir State AgrarianUniversity (Ufa, the Russian Federation) on leached black soils of heavy loam granulometriccomposition. The positive effect of calculated doses of mineral fertilizers on the object of interestwas evident. Fertilization increased the spring rape yield capacity and its oil content by0.34–0.51 t ha-1 and 0.1–1.8%, respectively. The yield of oil per hectare also increased. The useof fertilizers increased the content of nitrogen and potassium, averaging over three years3.32–3.36% and 1.00–1.03%, respectively. The use of fertilizers did not significantly effect thecontent of phosphorus. The content of phosphorus did not exceed 1.74–1.79%. Crude proteincontent was 19.4–19.6% for researched period.
