The aim of the experiment was to monitor importance of nitrogen in nutrition of oilseed rape (Brassica napus L.) as well as the effect of rising doses of nitrogen on yield and oiliness of rapeseed. The plot-scale experiment was based in year 2013 on locality Mojmírovce. Hybrid Artoga was used. There were five treatments of fertilization with size 600 m2 experimental plots in three replications, in this experiment. First treatment was unfertilized control treatment. Next treatments were fertilized by dose 120 kg.ha N, 160 kq.ha N, 200 kg.ha N and 240 kg.ha N. The lowest yield of rapeseed 3.41 t.ha was noticed at unfertilized control treatment 1. The highest yield 5.43 t.ha was found at the fourth treatment, where the dose of nitrogen 200 kq.ha was applied. aii content ranged from 45.91% to 47.41%, while the lowest aii content 45.91% was observed at treatment 3, where the dose of nitrogen 160 kg.ha was used. The highest aii content 47.41% was found at unfertilized control treatment
