During the 2010-2012 period in RIMSA, Troyan (Bulgaria) the comparative testing of two drought tolerant perennial grasses (switchgrass, indiangrass) with traditional grasses (orchard grass, smooth bromegrass, perennial ryegrass, tall fescue) was performed. It was found that the best adaptability had the switchgrass. In the double regime of harvesting it was obtained 1.96 t ha-1 green mass and 0.70 t ha-1 dry matter, which exceeded the standard (orchard grass) by 28.95% and 52.17%, respectively. All tested perennial grasses predominated over the weed plants and weed infestation increased from I to II haymaking.
