The results of determining sugar beet hybrids economic and energy efciency technology growing depending on the use of fungicides and microfertilizers are presented. The research was conducted in 2020–2022 in the “Svitanok” Agrienterprise of Vasylkiv district, Kyiv region. Research was conducted with two sugar beet hybrids (Pushkin, Akatsia), three variants of microfertilizers (control, YaraVita Bortrac 150 (3 l/ ha), YaraVita Mancozin (1 l/ha)) and three schemes of fungicide application (Stefstrobin (0.6 l/ha) + Shtefozal (0.5 l/ha) + Shtilvet (0.1 l/ha); Tserkostef (0.5 l/ha) + Shtefstrobin (0.6 l/ha) + Shtilvet (0.1 l/ha); Cerkoshtef (0.5 l/ha) + Shtefozal (0.5 l/ha) + Shtilvet (0.1 l/ha )) were studied. The evaluation of the fungicides and microfertilizers economic efciency was determined according to the prices for the end of 2022 according to generally accepted methods. The technology of sugar beets growing is generally accepted for the zone of the Right Bank Forest Steppe, except for the methods that were put to study. It was established that in the structure of economic costs during the cultivation of sugar beets, a signifcant part is occupied by the use of mineral fertilizers – 23.7 %, fuel – 18.6 %, plant protection products – 16.3 %, seeds – 13.5 %. In the structure of energy costs, most of it belongs to fuel (27.8 %), mineral fertilizers (26.9 %), equipment (19.7 %) and labor costs (15.7 %). Energy costs for plant protection products and microfertilizers make 4.5 and 0.7 %. The Akatsia hybrid has higher proftability rates (53245.7 UAH/ha), proftableness (164.9 %) and energy efciency ratio (3.6) compared to the Pushkin hybrid (45462.2 UAH/ha, 147.6 % and 3.3). From an economic and energy point of view, the combined use of microfertilizers YaraVita Mancozin (1 l/ha) and fungicides Tserkoshtef, k. s. (0.5 l/ha) + Stefstrobin k.s. (0.6 l/ha)+ Stilvet (0.1 l/ha) is the most appropriate. Efciency, proftability and energy efciency ratio were 51491.3 and 60394.3 UAH/ha, 161.9 and 181.5 %, 3.58 and 3.94, respectively, for hybrids Pushkin and Acacia. Key words: sugar beets, fungicides, microfertilizers, hybrids, economic efciency, energy efficiency.

Improvement of Biogas Yield by Pre-Treating Poultry Waste with Bacterial Strains

et al. 2021

Poultry waste is increasingly used as a substrate for the methane fermentation process in a biogas plant. However, not all waste materials processed in the meat industry meet the criteria for optimal process management and cost-effective methane efficiency. An example may be centrifuged biological sludge, etc. Treatment of such material used as a substrate by introducing new metabolically and enzymatically active strains of bacteria could be beneficial for the fermentation process in a biogas plant and provide increased energy efficiency. The aim of the study was to compare the amount and quality of biogas obtained from biological sludge from the processing of poultry vaccinated with metabolically diversified bacterial inoculum after initial incubation of the batch before the actual process in a biofermenter. Laboratory tests were carried out in accordance with the guidelines contained in the DIN 38 414-S8 and VDI 4630 standards. Based on the obtained results, it was found that the optimized biological sludge can be used as a substrate in the methane fermentation process in a biogas plant. The material processed by the combination of bacterial strains marked with the symbols A/C, E/G, and F/H showed a significantly increased efficiency of biogas, including methane, compared to the non-grafted material. This is a good predictor for industrial applications, process feasibility, economic viability, and environmental sustainability that should be compiled based on the results obtained from this study.

Purpose. To establish the effectiveness of methods of controlling the number of weeds on the energy productivity of sorghum and soryz in the conditions of unstable moisture in the western part of the foreststeppe of Ukraine. Methods. Field, laboratory, mathematical and statistical methods were used in the experiments. Thus, field research consists of studying the biological and ecological characteristics of growth, productivity and quality of the crop, including observation, recording of conditions and results. The purpose of the laboratory method is to identify the relationship between the plant and the environment (soil) through their analysis. Mathematical and statistical methods are used to process experimental data in order to increase the validity of the results. Results. Over the years of research, the species and quantitative composition of weeds in crops of sorghum and soryz was established. The highest efficiency of weed control was observed in the variant with manual weeding – 95.0–97.0%, with chemical treatment – 82.0–83.0%, with mechanical treatment – 78.6–88.5%. On the other hand, in the control variant (no maintenance), weediness increased by 10.3–13.9%. The lowest grain and biomass yields in the varieties ‘Dniprovskyi 39’ (2.35 and 22.23 t/ha) and ‘Samaran 6’ (2.50 and 22.7 t/ha) were obtained in the weeded variant (control); slightly higher for the mechanical treatment. The use of a chemical control method helped to increase the yield to 3.40 t/ha of grain and 29.07 t/ha of biomass in sorghum and 2.80 t/ha of grain and 27.73 t/ha of biomass in soryz; manual weeding – up to 3.90 t/ha of grain and 32.13 t/ha of biomass in sorghum and 3.50 t/ha of grain and 30.63 t/ha of biomass in soriz. Conclusions. The highest estimated yields of bioethanol and solid biofuel per unit area were obtained by manual weeding in the cultivation of sorghum (1.29 and 9.16 t/ha) and soryz (1.16 and 9.09 t/ha). The total energy output was 181.62 and 177.02 GJ/ha respectively. In other versions of the experiment, the noted indicators were lower. Correlation regression analysis of the data showed a strong correlation between grain productivity and bioethanol output, solid biofuel yield and output, grain productivity and energy output from bioethanol, biomass yield and energy output from solid biofuel. The correlation coefficient ranged from 0.87 to 0.99 and the coefficient of determination ranged from 0.78 to 0.99.
