Study on Behaviour of Mixed Grasslands of White Bentgrass under the Central Balkan Mountain

Agrostis stolonifera is primarily suited to cold and wet climates, but its range in warmer climates has been increasing in recent years. The aim of this study was to see how white bentgrass behaved in two-component mixtures with legumes native to the Central Balkan Mountains (birth's-foot-trefoil, blue alfalfa, yellow alfalfa, red clover, white clover, sainfoins). Parallel to this, the most common meadow grasses (red fescue, cocksfoot, timothy-grass, perennial ryegrass) were compared to a mixture of these species.For the fourth-year experimental cycle, the mixture of white bentgrass and bird's-foot-trefoil had the highest dry matter yield (1.61 t ha-1), followed by this one of red fescue and bird's-foot-trefoil, with no noticeable difference between them. In addition, the mixture of white bentgrass and red clover performed well. Its output was marginally higher than that of the “traditional” timothy-grass and red clover mixture.All of the white bentgrass/legume crop mixtures studied (except yellow alfalfa) had comparable or higher productivity than the "usual" ones, which is a requirement for their use in artificial swards. In terms of yield stability, the mixtures of white bentgrass and cock's foot with blue alfalfa had the best performance.
