    The aim of this study was to determine the relative nutritional value (RFV) of Festulolium braunii grown in a mixture with red clover on the background of different nitrogen fertilization. In 2007, an experimental objects of Department of Grassland and Green Areas Creation in Siedlce field experiment with mixture sowing was established. Experience factor was varied nitrogen fertilization: N0 - no nitrogen, N1 – 60 kg N · ha–1, N2 – 120 kg N · ha–1. Detailed study included content of fiber fraction NDF and ADL in % DM. Chemical analysis of plant material were conduced for all the cuts collected in the last two years of the experiment. It was done at the Institute of Technology and Life Sciences in Falenty. The results were used to evaluate the feed from mixture, which was conducted according to the of Linn test and Martin. The using of mineral nitrogen contributed to the increase in the relative nutritional value of the feed. The higher dose caused an increase in NDF content in the dry matter of plants, but did not decrease the RFV value. The best in terms of quality feed material was biomass collected from the spring regrowth. The study showed the usefulness of high the analyzed mixture in ruminant feedin.
