The Study of Several Perennial Fodder Legume and Grass Complex Mixtures for the Establishment of Temporary Pastures in Transylvanian Plain

Abstract

Intensification of extremely weather phenomena during vegetation period of plants determined serious problems for Romanian farmers by partial or total disparagement of cultures in the last years. These problems are also common for fodder producing farmers from Transylvania. Among the alternatives, which farmers can follow, the revision of structure and gravity of crops can be considered. Sown pastures with complex mixtures (more than three perennial fodder grass and legume species) well adapted to the new ecological conditions, through their multifunctional character, can represent real alternatives to annual fodder crops. In this paper the results of a study regarding 8 complex mixtures of perennial fodder species and a pure alfalfa crop, cultivated on three levels of fertilization, are presented. The M7 mixture (Trifolium pratense L., Lotus corniculatus L., Trifolium alexandrinum L., Dactylis glomerata L., Festuca pratensis Huds., Lolium x hybridum Hausskn.) on the third cutting recorded the smallest yield difference between the unfertilized variant and the variant fertilized with the highest dose.
