Studies of yielding and changes of species composition of pasture mixture sward in post-bog habitat (peat-muck and mineral-muck soils) were carried out in 1998-03. Six pasture mixtures were included in the experiments (BG-5, BG-6 by Barenbrug, Mkb-1 and Mkb-2 by Agri Land as well as P-1 and P-2 by Rolimpex). The studies revealed considerable differences in yielding of the mixtures tested, particularly in mineral-muck soil conditions. Yielding of the mixtures was more stable under peat-muck soil conditions. Species composition of mixture sward was much differentiated in relation to its composition during sowing. A higher variation was recorded for mineral-muck soil. In subsequent years, the share of grasses increased (Lolium perenne, Poa pratensis, Dactylis glomerata), and that of Trifolium repens decreased. In peat-muck soil conditions, the sward species composition was more stable with a clear increase in Poa trivialis share in the sward of the first cut in 2003, with a clear decrease in the share of Lolium perenne and Dactylis glomerata
