Description

The new highly productive ecologically secure elements of agrophytocenoses creation on sloping lands of southwestern Forest steppe of Ukraine have been theoretically, methodically sound and elaborated, based on using perennial energetic crops for solid fuels production. The effectiveness of sloping lands usage is determined based on creation of agrophytocenoses using energetic crops as a raw material for solid fuel production. At fifth-year miscanthus growing on various nutrition backgrounds and on different slope expositions, our research has established the increase of a crop green mass yield capacity by 23% (7,8 t/hа), dry matter by 35% (5,5 t/hа) on a northeast exposition slope at using 8 t/hа limestone flour and introduction of N60Р60К60 kg. a.s. (active substance), compared to similar options indicators at their location on southwestern exposition sites. The energy output per area unit herewith made 369,6 MJ. The same tendency has been observed for five years of research, regardless of a crop vegetation years. The highest indicators of cup-plant (Silphium perfoliatum) for years of research have been obtained when introducing limestone flour 8 t/hа, and mineral fertilizers in dosage N60Р60К60 kg. a.s., at row spacing 70 cm. In 2020, green mass- and dry matter yield made 42,6 t/hа and 20,7 t/hа, respectively. Herewith, the energy output per area unit made 363 MJ. The researches have shown that the switchgrass- and miscanthus productivity is higher at a single harvesting at the end of crop vegetation. The researches have shown that the highest miscanthus productivity is on sites using planting scheme – three plants per running meter for a single harvesting term. Green mass yield of 8-th and 9-th vegetation years made 35,6 and 38,9 t/hа, with dry matter output 18,5 and 19,8 t/hа. The energy output herewith made – 326,4 and 348,8 MJ/hа.
