The study followed the behavior of an assortment consisting of eleven varieties of spring oats, depending on the level of mineral fertilization, on the level of production, crude protein content and fats. Mineral fertilization with nitrogen had five graduations: N0, N30, N60, N90 and N120, applied on a constant background of P60K60. The sowing density also had three graduations: 350 seeds/m2, 450 seeds/m2 and 550 seeds/m2. The lowest production of 2961 kg/ha was recorded for the Lovrin 1 variety on the N0P60K60 agrofund and the density of 350 seeds/m2, and the highest of 4879 kg/ha for the Gentiana variety, on the N120P60K60 agrofund and 550 seeds/m2. The values of the protein content depending on the level of mineral fertilization ranged between 13.4 on the N0P60K60 agrofund and 15.05% on the N120P60K60 agrofund. As for the fat content, the highest value of 54.2% was also recorded on the agrofund fertilized with N120P60K60 and the Muresana variety.
