Abstract
Permanent grasslands are an important source of green fodder and fiber needed for animal nutrition. The experiment held on a meadow of Festuca valesiaca L. in the region of Moldavia, aims to improve soil nutrient regime by means of organic and mineral fertilization, that could change the floristic composition in favour to the valuable species. Pasture fertilization with 20-30 t ha-1 manure and N50+50 P72 caused production increases of 34-70%. Regarding floral structure, the predominant species are grasses (60-70%), followed by legumes (8-27% and forbes ranging 11-23%).

Key words: permanent grasslands, manure, yield, floristic composition
