Energy productivity of miscanthus giganteus depending on growing technology elements

Abstract

Increasing industrial production and global processes in the modern world lead to a significant rising in energy consumption which, as a consequence, causes the environmental damage. The development of unconventional and renewable energy sources should be seen as an important factor in improving energy security and reducing the anthropogenic impact of energy on the environment. In Ukraine, the large-scale use of renewable energy potential is not only of domestic but also of great international importance.It is a significant factor in counteracting global climate change, improving the overall state of Europe’s energy security (Heletukha H. H. аnd Zhelieznaia T. A., 2006). Therefore, scientists around the world are looking for the alternative sources of energy that could provide partial or complete energy independence. The soil and climatic conditions in Ukraine are favorable for the cultivation of crops with a high level of biomass energy accumulation during vegetation. Some unconventional crops capable of accumulating large biomass have significant prospects for bioenergy in Ukraine, in particular due to the fact that photosynthesis occurs over a long period - from early spring to late autumn. The results of studies of miscanthus productivity, biofuel yield and energy depending on the timing of planting rhizomes are highlighted in the article. The maximum yield of dry biomass of miscanthus plants is observed during planting rhizome in the second decade of April and is 15.3 t/ha, which contributes to the increase of yield of solid biofuels (up to 16.8 t/ha) and energy per unit area (up to 285.6 GJ / Ha).
