In a scientific project of the federal ministry of agriculture, forestry, environment and water management, lead by the LFZ Raumberg-Gumpenstein and in cooperation with various federal and national research institutes, 16 different grassland mixtures of the central European area were tested for their suitability in the Austrian alpine or mountainous grassland. Three-year-investigations on eight trial locations with two stages of intensity showed in detail the performance of the seed mixtures The results of the seed mixtures concerning persistence, yields and development of yields revealed big differences and lead to significant economic effects. Yield differences of up to 2.6 t DM/ha/yr, adjusted yields excluding weeds up to 3.1 t DM/ha/yr show the wide range of mixtures under the prescribed conditions. Differences of the forage quality between the mixtures were rather low, showing the high importance of well-timed harvesting. Site-adapted seed-mixtures, well-adjusted fertilization, timely harvesting and a good overall management offer perfect possibilities of development for grassland fodder production in alpine regions. The environment provides the general framework; optimized use of this framework is an important basis for successful grassland cultivation.
