Estimation of usage and fertilization impact on quality of Festuca rubra pasture and sustainability of some technological variants

The purpose of this research was to study the effect of some treatments (fertilization, oversowing, cutting, grazing) on a Festuca rubra mountain pasture from Cindrel Mountains (Meridional Carpathians, Romania), in order to improve the quality of this pasture. Yearly fertilization with organic fertilizers or moderate chemical fertilization (N100P22K83 kg-ha-1-y-1) positively influence some soil chemical features, the nutritional status with N of plants and the level of forage yields of this pasture. The amplification of N biogeochemical cycle in the variants fertilized with moderate dozes of N determines significant increases of quantity and quality of forage production. Key Words: Festuca rubra, cutting, grazing, yield, consumption efficiency.
