Rapeseed (Brassica napus L) is widely used in the production of oil, animal feed and biodiesel. Quality of oilseed rape depends on the genotype meteorological conditions and crop management. It is important to provide sufficient quantities of soil nutrients before planting (basal fertilization), so that young plants may form a leaf rosette and prepare for a period of low winter temperature. This research was performed on four commercial genotypes of rapeseed (Banaćanka, Slavica, Express and Valeska) produced in the growing season 2008-2009. The following parameters were determined: germination, 1000-seed weight, oil content and fatty acids. Seed germination, 1000-seed weight and oil content depended on the genotype, but not on the applied NPK dose. The fatty acids content depended on the genotype and the amount of fertilizer applied.
