The goal of the research is to assess the bioenergy efficiency of individual elements of sugar beet growing technology. Materials and methods. The experiment was conducted at the Training and Production Center (BCC) of Bila Tserkva National Agrarian University in 2015-2017. All field experiments were conduct on the background of the main fertilizer. Under the basic cultivation of the soil 40 t/h of manure and N120P100K140 mineral fertilizers (a.s.) were introduced, on the basis of the planned yield of 70 t/ha. Norms of organic and mineral fertilizers were calculated taking into account the presence of nutrients in the soil and the coefficient of their removal by sugar beet. The results of research. For the energy assessment of the elements of sugar beet cultivation technology in the central part of the Right-bank Forest-steppe zone of Ukraine, the cost of the total energy per unit area was determined by the technological maps, which were grouped and analyzed according to the following articles: seeds, fertilizers, fuels and lubricants, mechanized and manual work, and etc. The energy efficiency was determined by the energy efficiency ratio (Cee) – the ratio of the difference between the reproduced energy (energy consumption of the crop) and the consumed energy efficiency coefficient where the seed with the laboratory similarity was sown more than 95 % – (Cee = 5.51). When used for sowing seeds with a laboratory similarity of more than 91–95 %, the energy efficiency was slightly lower than that of sowing seeds more than 95 % and was 5.42. With the increasing of plant density to harvesting from 80–90 to 101–110 thousand/ha, the energy output from the harvest increased from 829521 to 905520 MJ, but due to higher yields in variants where the plant density was 101-110 thousand/ha of energy, comparatively before control was higher. The energy efficiency ratio tended to decrease both for the use of hybrids and for the introduction of trace elements in the feed and amounted to 5.57–6.08. Conclusions. It is proved that the developed agrotechnological measures for sugar beet cultivation in the line hybrid – the quality of the seeds – the plant stomatal density – fertilizers – the duration of the vegetation period, provide a high economic effect. The formation of optimal sugar beet seeding on the area provided the highest yield of energy with the yield on variants with double application of microfertilizers in the non-root nutrition. Key words: sugar beets, bioenergy efficiency, similarity of sown seeds, plant density, varietal composition, foliar nutrition, duration of vegetation period.

The article presents the indicators of economic efficiency of growing miscanthus biomass for the production of solid biofuels. The energy efficiency coefficient is calculated as the ratio of energy input to energy output. The aim of the study was to assess the efficiency of the use of plant growth-promoting and regulating products Vympel-K and Quantum-Gold in the cultivation of miscanthus biomass in the Left-Bank Forest-Steppe of Ukraine. Results. Return on investments starts since the third year of harvesting. The gross income after the fourth vegetation season was 392 900 UAH per hectare. The highest energy efficiency index (4.2−4.4) calculated for the first-year harvest was in the following treatments: single and double dose of NPK, single and double treatment with Vympel-K. Profitability in these treatments was the highest and ranged from 345.3 to 341.4%. The proposed new component of cultivation technology − soaking the rhizomes before planting in the growth-regulating and promoting products Quantum Gold and Vympel-K is economically justified. The return on investments after the sale of the miscanthus biomass for the use of these techniques starts since the third year of cultivation.

Global climate changes and fossil fuel reserve depletion are drivers for the search for environmentally friendly renewable energy sources. In Europe, biomass represents the main alternative to fossil fuels. Among energy crops, sorghum is a promising crop for arid regions. The biomass yield and energy efficiency of sorghum (both silage and grain) were studied based on field experiments conducted in Southern Ukraine. The following climate changes were identified: an increase in temperature and a decrease in precipitation. The total energy inputs for sweet sorghum were estimated at 11.256 GJ/ha. The main contributors to the energy inputs are mineral fertilizers (56.99%). The experiment showed that a yield of 40.6 t/ha could be achieved with annual precipitation of 350 mm. The energy efficiency ratio was determined to be 11.18. The total energy inputs for grain sorghum was 16.081 GJ/ha. Its yield (grain) varied from 1.92 to 7.05 t/ha. The energy efficiency ratio of grain sorghum ranged from 2.8 to 16.7.

In sugar beet production, one of the most important factors that affect the yield, apart from genetic properties, is the use of mineral fertilizers. Considerate amounts of mineral fertilizers are used in sugar beet production. However, if agroecological conditions are not optimum, mineral fertilizers cannot be completely absorbed, which may lead to soil contamination. Therefore, research has been focusing on ways of using atmospheric nitrogen by means of nitrogen-fixing bacteria. Numerous researches have proved that one part of mineral fertilizers can be replaced by biological nitrogen. The aim of this research was to determine the effect of genotype, azotobacter and the amount of mineral fertilizers on the root yield of sugar beet and on the microbiological activity of the sugar beet rhizospheric soil. Three hybrids of sugar beet were used during the two years of the research. The seed of the hybrids was inoculated with three strains of azotobacter. Various amounts of NPK were used (0;30;60;90 kg/ha). At the end of the vegetation period, the following were determined: root yield, total number of bacteria, number of azotobacter, oligotrophic bacteria, ammonifiers, fungi, and actinomycetes in soil. Dehydrogenase activity was measured. The results were processed statistically (analysis of variance for factorial trials) and the effect of the factors was determined upon the expected mean square values. The yield was mainly affected by the amount of mineral fertilizers. However, the effect of mineral fertilizers was different with different inoculation treatments. The effect of the examined factors was dependant upon genotype, amount of mineral fertilizers, inoculation and the year of trials. The interaction between genotype, mineral fertilizers, inoculation and the year of trials was the factor that had the greatest effect on the number of almost all the examined soil microorganisms.

The content of mineral nitrogen was studied when it was applied at a dose of 60 kg / ha on gray forest soil of heavy particle- size distribution at various levels of phosphorus-potassium nutrition in field experiments with barley. Fertilizer doses were determined by the normative method according to the CINAS method for a planned yield of 3 t / ha. It was shown that the dynamics of nitrate and ammonium nitrogen depended on the moisture regime during the vegetation period. With excessive moisture, nitrate nitrogen, with its initial content of 4-5 mg / kg, is not detected in the arable layer by the middle of the growing season, and with a moisture deficit, less dynamism is noted. It is found in an amount of 5-7 mg / kg by the end of vegetation. The N – NH4 + dynamics turned out to be less pronounced. With an excess of moisture, its content increased to 15.6 mg / kg, and with a deficit, it decreased more than by four times from the maximum during the vegetation. In general, the content of mineral nitrogen in gray forest soil is highly dynamic, which depends on the moisture regime and the nature of its consumption by barley.

The studies were carried out under the conditions of a microfield experiment on typical chernozem (Belgorod region) with two soils (pH 5.0 and 6.5) with the addition of urea (enriched in 15N, 17.1 at. %) And effluents from a pig-breeding complex (PSC) at doses of 6 and 12 g N/m2 (against the background of phosphate and potash fertilizers, P6K6). The largest amount of nitrogen was consumed by sugar beets with the combined introduction of CCA and urea (25.8 g N/m2). When the soil was acidified to pHsalt 5.0, the consumption of nitrogen in mineral fertilizers decreased by 15-18%, soil ni-trogen – by 21-52%, and waste nitrogen – by 16%. At the same time, the immobilization of nitrogen in the fertilizer decreased by 13-18%, and the loss of gaseous nitrogen compounds increased by 47-108%. The effluent from the pig-breeding complex increased the immobilization of nitrogen in mineral fertilizers (by 38-46%) and reduced gaseous nitrogen losses (by 22-44%). The highest stability and productivity (root crop yield 1654 g/m2, tops yield 239 g/m2) was exhibited by agrophytocenosis on soil with pH 6.5 with the combined application of CCA and urea. When the soil solution was acid-ified to pH 5.0, the yield of beet root crops decreased by 30% and the yield of tops – by 24%. On soil with pH 5.0, fertilizers increased the sugar content in root crops by 0.2-1.3%, on soil with pH 6.5, they decreased by 1.3-2.0%.

Problem and purpose. The purpose of the study was to study the efect of diferent doses of chicken manure (CM), zeolite (Z), their mixtures and mineral fertilizers on the accumulation of trace elements in the vegetative organs of spring rapeseed plants at diferent stages of development. Methodology. The experiment was based on the following scheme: 1) control; 2) N60P60K60; 3) Z 3 t/ha; 4) CM 2.5 t/ha; 5) CM 5 t/ha; 6) CM 10 t/ha; 7) N60P60K60 + Z 3 t/ha; 8) CM 2.5 t/ha + Z 3 t/ha; 9) CM 5 t/ha + Z 3 t/ha; 10) CM 10 t/ha + Z 3 t/ha. The content of trace elements of copper, manganese and zinc in plants was determined after dry salting at a temperature of 525 ± 25° C by atomic absorption. Results. The results of the experiment showed that the introduction of zeolite-containing rocks ofTerbunsky Deposit contributed to the reduction of such microelements as Cu, Zn and Mn in the vegetative mass of rapeseed throughout the entire period of plant development. Active adsorption of the zeolite-containing rock of Terbunsky Deposit in relation to Zn was revealed in the experimental plots using organo-mineral mixtures (CM 2.5 t/ha + Z 3 t/ha, CM 5 t/ha + Z 3 t/ha, CM 10 t/ha + Z 3 t/ha), which contributed to a decrease in the element in the vegetative mass of rapeseed in the experimental variants throughout the entire vegetation period of plants. Conclusion. Therefore, the conducted research allows to recommend the cultivation of spring rapeseed with the use of organic waste as fertilizers together with natural zeolite in the conditions of the forest-steppe of the Central Black Soil Region

Management of digestate from production of biogas has a great environmental importance. One of feedstock for biogas generation is beet pulp, a side product of sugar beet processing plant. In the paper a closed loop of beet pulp utilization at sugar beet plantation is presented. Effects of soil application of digestate obtained from digestion of sugar beet pulp were compared with standard mineral fertilizers. The field experiment was performed in three successive growing seasons. The studies were concentrated on quality of sugar beets grown under effects of two fertilization treatments—soil application of digestate cv. standard mineral fertilizers. It was found that some important quality indices (weight of single sugar beet root, content of sucrose in root tissues) were higher for beet harvested from digestate treatment compared to standard mineral fertilization (control). The concentration of harmful component (amide nitrogen) in sugar beets grown under conditions of digestate soil application was lower than in the control. It can be concluded that soil application of digestate from processing of sugar beet pulp can be treated as environmentally sound and effective method of its management.

The need to study energy crops as an alternative source of energy for providing the population and rural development is justified in the article. In the course of the study, the following methods were used: laboratory – to determine the moisture content in the phytomass, field – to determine the quantitative indicators of plants and biomass productivity, special – to determine the energy and economic efficiency of biomass production. Features of yield formation and yield of dry biomass of energy crops by quantitative indices of plants were determined. The economic and energy efficiency of biomass production, as well as the output of solid biofuel, its energy intensity and energy output have been calculated. A logistic scheme for biomass cultivation including the use and supply of biomass from biomass energy crops (from producer to consumer) has been developed. It has been found that switchgrass and giant miscanthus of the third to fifth year of vegetation form a high yield of dry biomass (up to 15.2 and 18.8 t / ha, respectively) with a maximum level of production profitability - up to 108.6% and 128.1%, provide high indicators of biofuel output (up to 18.2 and 24.0 t / ha) and energy (up to 313.0 and 396.0 GJ / ha) with an average level of energy efficiency coefficient (Kee> 4.5).

AbstractModern agriculture relies heavily on fossil energy for food production. Reducing fossil energy and replacing that energy with renewable energy is critical in attaining a sustainable food system. Hand-scale intensive food production offers a reduction in fossil energy and an increased use of renewable human-based energy. Using biointensive production techniques, onions (Allium cepa) were grown in Pennsylvania, USA. A life-cycle analysis was performed to monitor energy utilization. Individual human labor tasks were evaluated using the factor method. This method accounts for the type and duration of physical activity. The average yield of eight onion varieties utilizing biointensive production in standard-sized beds (9.3 m2;100 ft2) was 160.2 kg. The US average for mechanical onion production is 46.1 kg/9.3 m2 (100 ft2). The energy efficiency ratio, specific energy and energy productivity were 51.5, 0.03 MJ kg−1 and 32.2 kg MJ−1 (MJ=megajoule), respectively. When defined within common boundaries, these three relationships: energy input, energy output and yield productivity allow researchers, farmers and policy-makers to select production systems and/or practices that better manage fossil and renewable energy for food production. Current mechanized agriculture has an energy efficiency ratio of 0.9. With most energy being supplied by fossil fuels. The energy efficiency for biointensive production of onions in our study was over 50 times higher than this value (51.5) and 83% of the total energy required is renewable energy. Biointensive production offers a viable energy use alternative to current production practices and may contribute to a more sustainable food system.
