The study showed that the highest yield of energy willow biomass was obtained with a variant with a planting density of 15 thousand units/ha and mineral fertilizers, namely 113.7 t/ha of green mass and 64.4 t/ha of dry mass. In the fifth growing year of energy willow, an annual increase was achieved in the yield of freshly cut wood from 21.2 t/ha per planting step of 40 cm and without fertilizer application to 24.7 t/ha per planting step 50 cm with full fertilizer application.
The highest yield of poplar energy biomass was obtained in the variant of planting density of 6.7 thousand units/ha, namely 149.7 t/ha of green mass and 84.7 t/ha of dry mass. Application of mineral fertilizers increases the yield to 21.9-31.6 t/ha of green mass and 12.5-17.7 t/ha of dry mass in all variants of the experiment. Having analyzed the yield increase by years of vegetation, it should be noted that for the fifth growing year of energy willow, the lowest annual increase in yield of freshly cut wood was achieved from 5.3 t/ha per planting step of 40 cm and without fertilizer up to 14.0 t/ha per step planting 60 cm with full fertilizer application. The largest increase was obtained in the third growing year from 31.5 t/ha to 62.1 t/ha. Having analyzed the yield increase of poplar by vegetation years, it should be noted that for the fifth growing year, an annual increase in yield of freshly cut wood was achieved from 21.2 t/ha per planting step 40 cm and without fertilizer to 24.7 t/ha per planting step 50 cm with the introduction of the full rate of fertilizer. The same trend is observed in previous growing years.
