摘要

The study included results of the period from the 4th to 6th year after establishment of mixed swards of red fescue, cocksfoot, red clover and birdsfoot trefoil on the slopes of the Central Balkan Mountains with a difference towards the four cardinalpoints. At a low degree of soil gleying on the upper slope part, green mass was from 1540 kg/da at westerly exposure (var. B3, 1997) to 3650 kg/da at southeasterly exposure (var. B2, 1999). Dry mass yields were from at a high degree of soil gleying on the lower slope part, the green mass was from 870 kg/da at southeasterly exposure (var A2, 1997) to 2775 kg/da at northeasterly exposure (var. A3, 1999). Dry matter was from 287 kg/da to 905 kg/da, respectively. 425 kg/da to 1031 kg/da, respectively. Withprolongation of the use of the swards, the participation of red fescue increased. In some variants it reached to 91 % (var. B1, 1999). The participation of cocksfoot, red clover and birdsfoot trefoil decreased considerably and at the end of the studied period there were only traces of them in the swards. Weeds, with few exceptions (var. B2, 1999), varied from 6 to 17%.
