However, the highest yield of 29,6 t/ha received a variant of the fertilizer at the rate of N120P16K86. The results of the energy analysis Making the most effective dose of fertilizer (N120P16K86), the settlement by the planned yield of 20 t/ha biomass. As for this fertilizer on average two years of research, energy willow provided the highest yield solid biofuels 32,560 kg/ha and energy output (520960 MJ/ha) on the option without fertilizer (control), 15290 kg/ha and 244640 MJ/ha. Power factor thus was high and reached 13,6. Proved that growing energy willow on tverdonosnu biosyrovynu is economically viable. On average, two years probation largest growing net income (3261 UAH/ha) provided a dose of mineral fertilizers which are defined calculation method that is 120 kg/ha ai nitrogen fertilizer on the background of P16K86. On average two years of research found that the type of soil affects the productivity of perennial energy crops like grass (miscanthus, sit, svichhras) and woody (Japanese willow, trytychynkova, prutovydna) as dry biomass yield on dark-grey lehkosuhlynkovomu soil was at 0,9-0,5 t/ha higher than crops that are grown on sod-podzolic zv'yaznopischanomu soil. By growing perennial energy crops on two types of soil on average two years using the highest yield svichhras formed and Japanese willow on dark gray (5,0 and 4,3 t/ha) and sod-podzolic (4,4 and 3,4 t/ha). Established that by growing perennial energy crops, the highest energy output 88000 MJ/ha of solid biofuel yield at 5500 kg/ha received from biosyrovyny svichhrasu on dark gray soil lehkosuhlynkovomu total energy costs were thus 13085 MJ/ha. Among energy willows on the same soil, the highest yield solid biofuel and energy - 4730 kg/ha and 75680 MJ / ha respectively provided willow Japanese. Expenses total energy for a corresponding amount of crop biomass thus amounted to 16047 MJ/ha, and power factor - 4,6.
