Wielkosc i rozklad plonowania mieszanek pastwiskowych z udzialem wybranych odmian zycicy trwalej w siedlisku pobagiennym

Chosen cultivars of ryegrass in grass-legume mixtures under pasture management on peat-muck soil were evaluated during studies. The influence of these cultivars on mixture yielding in particular regrowths in following performance years was estimated. Application of chosen cultivars of Lolium perenne L. in mixtures did not affect the significant differentiation of achieved dry matter yields in particular years of study. Mean yields in 1997-2000 did not make significantly different in relation to control mixture (without ryegrass). However, it was found that significant differentiation of achieved dry matter yields from particular regrowths depending on performance year, as weil as differences of yielding of the same mixtures in years. Several cultivars of ryegrass applied in mixture more guaranteed the most optimum yielding distribution of pasture sward in vegetation season. Achieved results confirm great usefulness of most of studied ryegrass cultivars for mixtures with grass-legume plants onto peat-muck soil under pasture management.
