Tsyhanskyi V. Improvement of technological methods of sowing alfalfa cultivation fodder purposes in Right-Bank forest-and-steppe areas

Object of study - the processes of growth, development and the formation of alfalfa forage productivity depending on soil liming, growth method and seed treatment by biological preparations. The purpose of work was to identify dependencies the formation of alfalfa forage productivity of doses of soil liming, methods of seed treatment by biological preparations with plants growth regulator under no covering and under covering growth methods under conditions of Right-Bank forest-and-steppe areas. Research Methods - hypotheses, analogy, generalization, field, laboratory, mathematics and statistics (variance, correlation and regression), comparative billing. In the dissertation presented are results of researching peculiarities of the formation of sowing alfalfa forage productivity depending on soil liming, pre sowing seed treatment and growth method. Established is the influence of the above factors on plant growth and development, density of shoots, photosynthesis and symbiotic productivity of agrophytocenoses, yield formation and forage quality. Economic and energy valuation of technological methods of sowing alfalfa cultivation for fodder purposes was carried out. Proved is the positive effect of seed treatment by rythobofit in combination with regulator of plants growth Emistym C (15 ml/t of seed) and soil liming with complete dose of lime according to hydrolytic acidity under no covering and under covering growth methods. Tested and introduced in agricultural farms Vinnytsia region on total area of 42 hectares. Scope - agriculture
