    Economy’s agricultural sector potential in Ukrainian energy self-sufficiency forming
    (Київ, 2015) Karpenko, V.; Burliai, O.; Mostoviak, I.
    The authors analyze the alternative types of energy production in Ukraine. It has been found out that Ukraine is an energy-dependent country and the main sources of energy consumption are fossil fuels. The share of renewable energy sources in Ukraine is less than 2%, which is one of the lowest indicators in Europe. However, Ukraine has a massive unused potential for energy savings in the form of natural renewable energy sources. In particular, there is a large amount of biomass available for energy production. The economically justified energy potential of existing biomass waste is about 25 million tons and the energy potential of biomass which can be grown on unused agricultural lands covering more than 4 million hectares is about 13 million tons. Due to this potential, we can cover up to 18% of total primary energy consumption in Ukraine from two above-mentioned sources. Thus, agriculture of Ukraine has a significant potential for its bioenergy development.

    Microorganisms number in sorghum (Sorghum bicolor (L.) Moench) rhizosphere after herbicide, plant growth regulator, and a biopreparation use
    (Wydawnictwo Uniwersytetu Przyrodniczego w Lublinie, 2021) Karpenko, V.; Krasnoshtan, V.; Mostoviak, I.; Prytuliak, R.
    In the modern agricultural production, the use of herbicides and other biologically active substances is an important part of the cultivation technologies of most cereals, including the grain sorghum. It is known that most preparations, including the chemical ones, can directly or indirectly influence the development of microorganisms in the rhizosphere of plants, but the nature of their effect on the microbiota of grain sorghum rhizosphere has not been studied enough, which reasoned the relevance of this research. Microbiological activity of the grain sorghum rhizosphere (hybrid Milo W) was studied during 2019–2020 under the treatment by the herbicide Citadel 25 OD (0.6; 0.8 and 1.0 l/ha), plant growth regulator Endophit L1 (30 ml/ha) and biological preparation Bioarsenal (800 g/ 100 kg). The analysis of the obtained experimental data showed that use of the studied preparations both separately and in different compositions had a stimulating effect on the number of grain sorghum rhizosphere microbiota, which was observed in its increase, especially in variants with the combined use of the herbicide Citadel 25 OD, plant growth regulator Endophit L1 and the biopreparation Bioarsenal (compared to the control the number of rhizosphere microbiota increased by 29.4–80.6% in average by groups).
