The aim of the research is the formation of polyvid hay-pasture grass stand based on Bromus inermis under growth stimulants. The paper presents the study results for 2015-2018 with the assessment of seed quality indicators, seedling completeness, plant height and aerial mass gain. Our studies have shown that when studying grass stands based on Bromus inermis, the parameters for grass stands with leguminous components have good indicators. The best option is Bromus inermis + Bromopsisriparia + Sainfoins. It is also good when there is Bromus inermis + Bromopsisriparia +Medicago. The study observations showed that the stems growth in height occurs at the beginning of the growing season gradually from the tillering phase in cereals and branching in legumes, to the phase of fruit formation. Our studies also proved that the more components in the mixture, the higher its productivity. The use of growth stimulants (GUMI 20M and Growth Matrix) leads to changes in the parameters of grass stands and the accumulation of aboveground mass. The highest indices are in the phase of fruit formation with maximum values in grass mixtures with legumes.
