Abstract
The permanent grasslands in the central-southern part of the Căpățănii Mountains located between 450–2,120 m altitude are rich in plant species, registering a number of 54 cormophytes in the 163 associations described. The general coverage with vegetation was 95%, of which 60% were valuable forager species and 35% harmful to the grass carpet. At the level of phytosociological alliances (habitats), the highest forage green mass (GM) productions were evaluated for Agrostion stoloniferae (17.2 t/ha), Arrhenatherion elatioris (12.9 t/ha) and Cynosurion cristati (12.2 t/ha) that allow an average load of 1.1–1.5 LU/ha. The lowest GM yields of 0.3–0.4 t/ha with a loading below 0.1 LU/ha were in Filipendulo-Petasition and Calthion palustris. The achievable milk production was 68–80 hectoliters per hectare for the three best alliances with the highest GM and PV production shown above. Very low results in milk production were evaluated in alliances with the lowest VM productions and the lowest PV indices presented earlier. The data regarding the evaluation of economic productivity indices (GM, PV, LU/ha, Milk/ha) continue to serve for the correct preparation of pastoral arrangements and the optimal management of mountain grasslands.
