DENSITY DETERMINATION OF ALFALFA-CEREAL HERBAGE DEPENDING ON SPECIES COMPOSITION AND LEVEL OF MINERAL NUTRITION IN CONDITIONS RIGHT-BANK FOREST-STEPPE OF UKRAINE
Keywords:
alfalfa-cereal grass mixture, species composition, fertilizing, densityAbstract
The article presents results of three-year studies on cultivation alfalfa and cereal grasses in conditions Right Bank Forest-steppe Ukraine. The influences of grass mixtures species composition, seeding rates of alfalfa and cereal grasses and doses of mineral nutrition on density formation of coenoses, the most optimal types of grass components, seeding rates of alfalfa for creation grass mixtures with alfalfa was established. was find out, that density of alfalfa-cereal grass mixtures depended on weather conditions, species composition of grass mixture, seeding rates and fertilizing doses. The largest number of shoots 1285 pcs / m2 was provided by grass mixture, which includes alfalfa, awnless brome and perennial ryegrass.Substantial influence on grass density was provided by influence of mineral fertilizers N60P60K90 and growth stimulator Fumar.
