Sažetak

Wheat is the second most important crop in the Republic of Croatia. With the introduction of the Code of the purchase of grains and oilseeds, in addition to grain yield, increasing importance is attached to the parameters of wheat grain quality, primarily protein content and test weight, which directly affect the wheat price at purchase. The genetic potential of the variety as well as the environmental conditions directly affect the stated parameters. Three-year research conducted at the location of Staro Topolje on 12 winter wheat varieties grown under three different levels of nitrogen fertilization, evaluated the effect of year, variety and treatment with nitrogen fertilization on protein content, hectolitre mass and thousand seed weight. For protein content significant effects of the year, variety and treatment with nitrogen fertilizer were determined. The year had the greatest effect on this trait, then treatment with nitrogen fertilizer, and the variety had the smallest effect. Significant effects of year and variety were also found for hectolitre mass, while treatment with nitrogen fertilizer did not significantly affect this trait, with the effect of year being considerably higher as compared to the effect of variety. It was also observed that all tested varieties responded equally to nitrogen fertilizer treatment. The average protein content at the lowest amount of applied nitrogen fertilizer was 11,08%, at the medium 11,95%, and at the highest 12,89%.
