Wieloodmianowe zasiewy motylkowo-trawiaste sposobem na zwiekszenie roznorodnosci florystycznej i wartosci paszowej runi pastwiskowej

Assessment of the effect of sown mixtures composition on floristic composition and value of pasture sward was a purpose of the studies. White clover maintained the best in the sward. There were confirmed higher seasonal changes of white clover, bird trefoil, black medic and alfalfa content in the pasture sward on mineral soil than on peat-mursh soil. Introduction of some perennial ryegrass cultivars ensured predomination of this species in the sward even under peat-mursh soil conditions.
