Abstract The influence of seeding techniques, level of fertilization and species composition of perennial grass mixtures on the formation of vegetation density and intensity of reaching cut-sample matureness were highlighted. The following types and varieties of grasses were used: Medicago sativa variety Synjuha, Digraphis arundinacea variety Kyi’vs’ka, Agropyrum tenerum variety Marusynskyy, Bromus inermis variety Arsen, Festuca pratensis variety Katrina, Dactylis glomerata variety Ukrai’nka, Poa pratensis variety Pryjekul’s’kyj. The effect of sowing in one line and the divider by two lines was studied in this experiment. The largest number of shoots per 1 m2 provide travosumishky, which include Medicago sativa, Dactylis glomerata and Bromus inermis with Poa pratensis. The density of such mixtures for making complete mineral fertilizing and seeding method was band 1064-1095 pcs./m2.
