Aspects Concerning Species Dynamic in a Complex Forage Mixture

The numerous studies undertaken in seeded grasslands topic showed that plant species have large reserves to increase productivity and quality of feed, but the mechanisms responsible for this still needs to be studied. Since these complex communities are made up of perennial species, understanding their long-term dynamics has an important role in developing a proper management. The present study aims to follow species dynamics on a complex forage mixture formed by Trifolium pratense (15%), Lolium perenne (20%), Festulolium (25%), Phleum pratense (15%) and Dactylis glomerata (25%) under the influence of different technological inputs. The final objective is, on the first place to identify the interactions which occur between the species which form the complex forage mixture and on the second place to track forage productivity and quality. In order to respond to the objectives proposed we analyzed the data registered on a period of two years, data regarding feed DM production and chemical composition. The results highlighted positive interactions between species dynamics and forage productivity and quality.
