There was noticed the best pasture surface cover in the year of experiment establishment. Turfness of pasture with Poa pratensis in the sward was better than in pasture with Lolium perenne content, except the turfness in sowing year. That time, fast growing perennial ryegrass was a predominant species in the sward. High soil moisture was conductive to expansion of Lolium perenne. However, observations carried out in autumn confirmed higher values of pasture surface cover. It was a result of progressive development of Poa pratensis and high regenerating ability of Lolium perenne. Grass-clover mixtures in both experiments covered pasture surface better than grass mixtures. There were noticed significant differences between turfness in grass and grass-clover treatments with Anda and Alice white clover cultivars, under Poa pratensis experiment and in relation to treatments with Armena and Alice white clover cultivars under Lolium perenne pasture. Content of white clover in pasture cover during spring and autumn was not as high as in sown mixtures, but amount of this species in the sward increased during warmer part of vegetative season. Presence of white clover in the sward ensured better turfness productivity of pasture. Results of carried out studies confirmed direct proportional relationship between pasture surface cover and productivity of pasture. Productivity of grass-clover sward was similar to productivity of grass sward, fertilized with nitrogen in dose of 80 kg ha⁻¹. Higher nitrogen fertilization was detrimental to pasture cover and its productivity under postboggy habitat.
