The experiment was carried out in order to evaluate the botanical composition and quality of fodder from perennial forage grasses (Festuca rubra L., Lolium perenne L., Dactylis glomerata L., Phleum pretense L.) grown in monoculture and in two-component mixtures with Trifolium pratense L. (50:50%) under mountain conditions. It was established that the studied grass species showed good adaptability and resistance to the specific soil and climate conditions of the experimental area. The relative share of grass species in monoculture meadows varied between 92.3% and 98.8%. The highest CP content in dry matter was recorded in Dactylis glomerata L. (101.4 g kg-1) and Phleum pratense L. (97.9 g kg-1). CP values exceeded the average by 6.1% and 2.4%, respectively. For the conditions of the Central Balkan Mountains, the mixtures of Festuca rubra L. and Phleum pretense L. with Trifolium pratense L. had the most balanced botanical composition (the ratio of grasses and legumes in the forage mass was 39.7:44.8% and 37.8:41.2%) and with the highest CP content. The indicator exceeded the average value by 37.8%, respectively 36.8%.
