The aim of this master thesis was to evaluate the effects of variety, sowing density and different nitrogen management on yield and quality performance in growing season 2012/13. It is based on the results of one-year field trials in two climatically different locations (Leopoldsdorf i. M. and Kautzen- Waldviertel) in form of a 3-factorial strip-gap system with six varieties, four nitrogen fertilization variants, three seed rates and three replicates. In Leopoldsdorf i. M., the more favorable values for the collected parameters (spiked number stalks, grain yield, protein, protein yield, thousand-kernel weight, gluten) were achieved as expected. In baltic climate higher values for test weight, falling number, number of spikelets / spike and plant height were recorded. A significant difference aroused between the sites and species on yield. In dryland the yields of Austrian varieties were higher as those of the Ukrainian varieties Lybid and Poliska 90 exceeded the yields of Austrian varieties Poliska 90 at Kautzen. Regarding the nitrogen fertilization management the highest grain yields were achieved at Kautzen by two-part nitrogen dosage (N 120 kg/ha). However, the protein value was marginally lower compared to the N3-fertilizer variant with 180 kg N / ha. In the dry area, the highest grain yield with the highest protein value was achieved by the N3 variant. In terms of protein yield the outcome in Kautzen was not affected by the various N-fertilizing variants. Minor differences between the varieties were detected. In pannonian climate, the N3-fertilizer variant showed the significantly highest protein-yield. At both locations, a location- and recovery-oriented nitrogen fertilization led to higher grain yields and higher protein contents. In addition, a significant variety-based impact was observed. The results showed that in 2013 a seed rate of 400 grains/m² resulted in higher grain yields and favorable quality features.
