The research was set up in 3 replicates compatible with split parcel experimental design tecnique in random blocks. Three different fiddleneck varieties (Sağlamtimur, Stala, Enton) were sown to main parcels and 5 different nitrogenous fertilizer doses (0 kg/da, 2.5 kg/da, 7.5 kg/da, 10 kg/da) were applied to sub-plots. Plant height, fresh herbage yield, hay yield, dry matter yield and crude protein yield are recorede in the experimental. CV Stala were found superior regarding it`s plant height (72.65 cm, 84.76 cm), fresh herb yield (2138.00 kg/da, 2385.60 kg/da), hay yield (510.83 kg/da, 554.60 kg/da), dry matter yield (456.55 kg/da, 495.99 kg/da) and crude protein yield (72.92 kg/da, 76.43 kg/da) in 2013 and 2014. The nitrogen dose for a high-yield and high-quality production was determined as 10 kg/da. Keywords : Fiddleneck, fresh herb yield, nitrogen fertilizing, quality
