CONTRIBUTIONS TO THE ASSESSMENT OF GRASSLAND HABITATS PRODUCTIVITY IN THE MUREȘ GORGE

Abstract

The permanent grasslands in the Mureș Gorge, between Toplița and Deda, located between 500 - 750 m altitude, in an area with a tradition of animal breeding, have a fairly high productivity. On average, the pastoral value (PV) is 50.6 and the green mass production (GMP) 9.33 t/ha, on which 0.87 LU/ha can be maintained during the 165 days of the grazing season. The normal Habitat 6520 with the Phyteumo - Trisetion and Cynosurion alliances has the highest productivity (68 PV and 12.9 t/ha GMP), 4-5 times higher than the degraded Habitat 6210 with the Seslerio - Festucion pallentis alliance (16 PV and 2.37 t/ha GMP). Data on grassland productivity further serve to assess potential forage and utilization with livestock.
