Abstract
The research is carried out on the Pyrus pyraster grasslands from Jimbor village commune Homorod, on the floor of the oak forests. Our study makes an analysis of the connections that exist between Pyrus pyraster trees and grasslands in terms of floral composition, nutritional and pastoral quality of herbaceous layer, analyzes the amount of nutrients in the soil and necessary for plant development and it also evaluates the production of nutrients per hectare, both under the canopy of Pyrus pyraster trees, as well as in the open field. The number of species found in the herbaceous layer of shady ground is with 22 % larger than in the open field, and the participation of fodder species is 24 % higher under the canopy of trees than in the land in full sun. The most found species under trees is Lolium perenne, it’s participation percentaje being almost 4 times higher than in the open field, this influencing the green mass production which is 14 t/ha. The nutritional value of the feed consumed by the animals grazed is very good being supplemented in the autumn months with ripe forest pear fruits.
