The study evaluated the effects of sowing density, tillage system, and fertilization level on the performance of winter oilseed rape (Brassica napus L.). The research was conducted under field conditions at the Agricultural Research and Development Station (SCDA) Lovrin, Romania. A factorial experimental design was used, including two sowing densities, two tillage systems (plowing and scarification), and two fertilization levels, with emphasis on nitrogen input. The observations focused on the production components (thousand kernel weight and seed production). Sowing density
significantly influenced plant architecture and yield formation, while the tillage system affected crop establishment and growth dynamics. Plowing generally ensured better early development, whereas scarification represented a suitable alternative depending on soil and climatic conditions. Higher fertilization levels led to increased yield performance, with responses varying according to sowing density and tillage practice. The interaction between experimental factors highlighted the importance of integrated crop management for optimizing winter oilseed rape productivity. The results
contribute to improving cultivation strategies adapted to local pedoclimatic conditions in western Romania.
