The object of study - the formation of forage productivity sown cereal and legume-grass mixtures, their botanical and species composition, crop structure under technological methods of cultivation. The purpose of research - to develop technological methods of creation and efficient use of sown perennial agrophytocenoses to ensure high and sustainable productivity of arable lands in the western forest-steppe. Research Methods. In carrying out investigations, the following general scientific research methods: induction and deduction (analysis and synthesis of research results), analogy (conducting comparison between control and experimental variations), generalization (opinions and suggestions) or special: field - monitoring the growth and development of plants under the growing season, yield formation; Laboratory - determination of the chemical composition of grass mixtures, the accumulation of dry matter in the meadow plant communities, mathematical and statistical - variance, correlation, regression - evaluation of the reliability of experimental data; comparative calculation - determining yield and forage quality, cost-effectiveness investigated elements technology. Scientific novelty of the results is that under steppes of the West, first in meadow fodder investigated ways presowing seed alfalfa seed, which is to optimize catalyst concentration of bacterial growth and the use of the drug. Studied the effect of foliar feeding new modern fertilizers Tryamin Plus for passing processes of growth and development agrophytocenoses perennial, forming their productivity, biochemical composition of feed and its energy value at different modes of use. The process of forming the stern performance legume-grass zlakovho modes depending on fertilizer use and various forms of nitrogen fertilizers. Research results Technological methods of creating and using agrophytocenoses meadow sown under which, in the early disposal of grass should be used as a nitrogen fertilizer ammonium nitrate, while late - Lime ammonium. Dry matter yield is respectively 7,00 and 9,78 t / ha. The level of profitability at the same time is respectively 27.0 and 71.6%. The highest productivity of dry matter cereal agrophytocenoses was in making N180P60K60 - 9,57 t/ha, but more cost effective has been making N135P60K60 profitability of 13.9%. Processing seed alfalfa crop growth promoters and bacterial drug Viva Ryzobofit, making phosphorus-potassium fertilizer P60K60 surface and provide Tryaminu Plus foliar dry matter yield alfalfa grass-cereal at 10.54 t/ha with profitability of 66.5%.
