Oilseed rape is an agronomically important species grown for seed that contains 40-48% oil and 18- 25% proteins. Oilseed rape has high demands for nitrogen. The research was performed on four varieties of oilseed rape (Banaćanka, Valeska, Slavica and Express) developed at Institute of Field and Vegetable Crops in Novi Sad, Serbia, during vegetative seasons 2007-2008 and 2008-2009. During vegetation, top dressing was applied with different amounts of KAN: control (0 kg N/ha), 50 kg N/ha, 100 kg N/ha, 150 kg N/ha and the N quantity determination were performed applying the balancing method (also known as N-min method). Yield, 1000-seed weight, seed germination, oil and protein content were determined after harvest. Yield and seed germination depended on seed production year. 1000-seed weight depended on seed production year and genotype. Oil and protein content in seed depended on production year, genotype and amount of the N-fertilizer applied by top dressing.
