ABSTRACT / SAŽETAK:

The aim of this study was to examine the influence of harvest time and nitrogen fertilizer application on the content of total polyphenols, flavonoids and condensed tannins in the dry matter of Italian ryegrass. The plants were harvest in 2017, in spring and early summer. The results obtained in this study showed that the contents of polyphenols, flavonoids and condensed tannins in the dry matter of Italian ryegrass (12.45 g / 100 g dry matter, 7.45 g / 100 g dry matter and 956.55 mg / 100 g dry matter, respectively) were higher when the plants harvested in early summer than in the spring. The application of nitrogen fertilizer did not have effect on the synthesis of polyphenolic compounds.
