Abstract (English):
The study results of cenotic activity of the perennial cereal and leguminous grasses in the second year of growth in the process of vegetation period depending on the nitrogenous fertilizer norm on the background of P 60K 60 are given in the article. Grass mixture component role in forming the above ground mass yield depending on mowing and nitrogenous fertilizer dose is determined. Cenotic grass activity changed in the vegetation period time and depended on the nitrogenous fertilizer norm.
