Winter oats has a special importance in the areas in which winters are soft since the yielding capacity of winter cultivars is superior to that of spring cultivars. In the studied domain, depending on the cultivar and fertilisation level, crops varied between extreme limits – 3268 kg/ha and 3943 kg/ha. To mention that during the trial cycle 2005-2007, there were climate abatements compared to multi-annual means of the area. Crop response curves pointed out in the studied cultivars maximum yields between 3581 kg/ha in the Florina cultivar, 3914 kg/ha in the Mirabel cultivar, and 3928 kg/ha in the Nupţiale cultivar for the nitrogen doses in the studied domain. Mean protein content increased together with the dose of nitrogen as follows: between 12.9 (N 0 ) and 14.2 (N 150 ) in the Florina cultivar, 12.5 (N 0 ) and 13.8 (N 150 ) in the Mirabel cultivar and 12.7 (N 0 ) and 14.0 (N 150 ) in the Nupţiale cultivar.
