During the years of 1976-80 the botanical composition of sward of meadow mixtures of different share of timothy and orchard grass was investigated on silt soils of the Vistula river valley in conditions of varying nitrogen fertilization. It was found that orchard grass content in sowing mixtures on permanent grasslands should not exceed 10 percent. A higher content caused suppression of other valuable grasses and white clover. This process was accelerated by the increase of nitrogen doses from 160 to 320 kg N/ha.
