THE EVOLUTION OF THE FLORISTICAL COMPOSITION AND DRY MATTER YIELD IN A FESTUCA RUBRA MOUNTAIN PASTURE AS INFLUENCED BY SOME TECHNOLOGICAL INPUTS
Keywords:floristic composition, Festuca rubra, yield
AbstractThe paper presents the results of research regarding the evolution of both forage yield and floristic composition, as influenced by mineral fertilization (N100, P50, K100), organic fertilization (sheepfold), liming (CaCO3) and over-sowing, on a long-term experiment, conducted on a Festuca rubra pasture from the Cindrel Mountains, Romania. Four years after experiment installation, the obtained results show that the most important modifications concerning both floristic composition and forage yield levels were produced in the case of the complete fertilized (N100P50K100) and liming variant, respectively in case of P50K100 fertilized + over-sowing with Trifolium repens variant placed on limed soil. After eight years, the research results distinguish interesting modifications for N100P50K100 and P50K100 fertilized variants, as well as for the organic fertilized variant, all of them on limed soil.
