Економічна та енергетична ефективність вирощування різних сортів конюшини лучної на кормові цілі

Abstract

Establish changes in the indicators of economic and energy efficiency of growing different varieties of clover for fodder purposes, depending on the methods of sowing, inoculation of seeds with nodule bacteria and fertilizers. Methods. Field and laboratory - for research in the field and laboratory conditions, analytical - to determine the chemical composition of the dry biomass of meadow clover, calculated - to determine the indicators of economic and energy efficiency. Growing meadow clover for fodder purposes on chernozems of typical low-humus northern part of the Right-Bank Forest-Steppe of Ukraine is profitable. Regardless of the elements of technology, it provides 14962-23743 UAH of net profit with a profitability of 88-259 % and the cost of 1 ton of feed units – 1415-2662 UAH and crude protein – 5363-10265 UAH, payback of energy consumption per 1 ha gross energy (KEE) – 6.2-9.0 and the output of 1 ha of exchange energy (BEC) – 3,2-4,6, as well as energy costs per 1 ton of feed units 2.86-4.20 GJ. The best indicators of economic and energy efficiency of meadow clover cultivation are provided by the Typhoon variety by inoculation of seeds with nodule bacteria on a background without fertilizers. Additional application of P60K90 or N60P60K90 on the background of inoculation, which is necessary to maintain soil fertility, worsens them, reducing the net profit by 3486-5943 UAH per ha.
