Silets'ka О. Agronomic evaluation of an established perennial alfalfa stand, improvement of its condition by fertilizer application and seeding fodder crops into it

The object of researches is agroland-reclamation estimation of sowing perennial alfalfa, backlogs of rise of efficiency of its growing in the year of throwing open. Purpose of researches - Study of possibility and expedience of sowing perennial alfalfa winter, early spring and late spring green crops on a background the application of different doses of mineral fertilizers. Methods of researches - the field; laboratory; computation; statistical. Results of researches - For a theory: The sowing fields of alfalfa are first conducted by perennial rape winter, early spring (barley, oat, rape, a radish is oil-bearing) and late spring (corn, sudan grass) green crops in co-operation with the mineral fertilizers, and without them. Technology of the use of the field of alfalfa of perennial in the year of its throwing open is improved. For practice: The offered recommendations enable to multiply production of forages and improve their quality. An agrotechnical complex on area requiring irrigation the south of Ukraine at bringing of fertilizers and sowing green crops in thin is developed grass alfalfas are provided by the output of greater quantity of green mass with the best quality due to mixing of them at harvesting. Thus on 20% economy watering water is used, productivity of the use of sun heat rises, the index of the use of irrigation earth is multiplied. The sphere of the use is the agricultural enterprises of south of Ukraine.
