CONTRIBUTIONS TO THE ASSESSMENT OF GRASSLANDS PRODUCTIVITY FROM CĂPĂȚÂNII MOUNTAINS

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.
