“…Over the last decade, the global production of biogas has tripled, which makes it possible to partially replace fossil fuels, and the production of biogas through anaerobic fermentation, which generates a significant amount of by-products (digestates) (Karimi et al 2022;Palamarchuk et al 2020;Urra et al 2019). In many countries, the potential of biogas production, although it has high efficiency, has not yet been fully utilised (Meyer et al 2018;Gontaruk et al 2024).…”

The paper highlights calculations of bioenergy indicators when growing corn for grain and vegetable crops in Ukraine. The research results indicate the economic benefit of growing these crops for all the variants studied. Our research established that an increase in the bioenergy efficiency of the production of these crops is achieved due to the use of different rates of fertilizer application. The increase in productivity that was obtained as a result of the implementation of farming practices exceeds additional costs associated with the use of fertilizers. This confirms the economic benefit of producing these types of crops due to the enhanced bioenergy efficiency achieved through the optimal application of fertilizer. The conducted research confirms the high energy efficiency of the bio-organic fertilizer (digestate) and the energy-saving technology of growing crops which were studied. High values of the coeffi-cients of energy efficiency were also observed in the variants with the simultaneous application of mineral fertilizers (N 90 P 90 K 90 ) and digestate-based bio-organic fertilizer "Efluent" (55.0 t/ha) on experimental sites of corn grown for grain (3.05-3.07), carrot (1.41-1.45) and red beet (1.97-2.00), but the cost of these variants also appeared to be the highest. Scientific research has used new methods and technologies for the effective processing of livestock waste in order to obtain organic fertilizer, which can be used to improve soil fertility and increase crop yields on the one hand, and biogas production as an energy-efficient process that has significant potential for producing ecologically clean and renewable energy on the other. The proposed approach to achieving energy efficiency helps to increase crop yield without increasing fertilization costs.

“…There is no universally accepted single name for fermented sludge from a biogas plant. In domestic and foreign literature, it is defined in different terms: effluent, biofertilizer, bioorganic fertilizer, digestate, biogas sludge and biosludge (Palamarchuk and Krychkovskyi 2020;Macadi 2012;What is digestate? 2009).…”

“…Foreign researcher J. Abubaker claims that the use of digestate stimulates the growth of soil microorganisms and their metabolic activity (Abubaker et al 2012). Digestate obtained from a biogas plant can increase crop yield by 10-30% compared to manure (Palamarchuk and Krychkovskyi 2020;Makádi et al 2012). As a result of the conducted experiments, when the digestate from the biogas plant was applied, it was established that the yield of potatoes increased by 30%, the yield of perennial lawn grasses increased by three times, cabbage and tomato seedlings increased by 12-15%, and biomass in general increased by 30-50% (Datsko and Maistrenko 2012).…”

This paper presents calculations of the economic indicators of the researched elements of the cultivation technology of corn for grain and vegetable crops in Ukraine, which indicate that the cultivation of these crops is cost-effective in all variants of the experiment. The research has established that the increase in the economic efficiency of the production of these crops when applying different rates of fertilizers is achieved due to a more significant positive effect of the increase in productivity compared to additional costs associated with the use of these farming practices, while additional costs caused by the use of fertilizers are paid off many times over. It has been proven that the use of mineral fertilizers and their combination with high rates of bio-organic fertilizer (digestate) when growing agricultural crops helps to increase productivity. There have been further developed theoretical and practical provisions regarding the ecological problem of livestock waste disposal, 162 in particular those of pig farms, and agricultural farms, i.e. the provision of organic fertilizers to ensure the yield increase as well as improvement in the quality of agricultural and vegetable crops, so as to make it possible to obtain high-quality products of plant and vegetable production during livestock waste disposal. The proposed approach to the economic assessment of technologies for growing corn for grain and red beet depending on the fertilization system makes it possible to increase the level of productivity of agricultural and vegetable crops with the effective use of bio-organic fertilizers in the modern conditions of sharp increases in the costs of mineral fertilizers.

Purpose. To highlight the features of influence of bioorganic fertilizer Effluent, obtained on the basis of anaerobic fermentation of pig manure in a biogas plant, on the productivity and yield structure of carrot and beet; to substantiate effective norms of the Effluent bioorganic fertilizer application in modern technologies of cultivation of carrot and beet. Methods. Observation, comparison, analysis and synthesis, system analysis and forecast. Determination of yield structure and productivity was performed according to generally accepted methods. Results. The largest diameter of the root crop (6.0 cm) in the Bolivar F1 carrot hybrid was obtained by applying the organic fertilizer Effluent at the rate of 55 t/ha in combination with mineral fertilizer (N90P90K90). Application of fertilizers provides an increase in the carrot root diameter by 0.6-2.4 cm, the weight of the tops by 11.4-24.3 g compared to the control. The highest total yield (67.66 t/ha) of carrots of the Bolivar F1 hybrid was got on the variant with applying 55 t/ha of bioorganic fertilizer Effluent in combination with mineral fertilizers (N90P90K90), of which 54.05 t/ha of root crops or 79.89% to the total yield were of saleable quality, and only 13.61 ton, or 20.11% were non-standard. Application of bioorganic fertilizer Effluent and mineral fertilizers provided an increase in the diameter of the root of the hybrid beet Kestrel F1 by 1.03-4.12 cm compared with the control. The weight of root crops under control (without fertilizers), for two years of the research amounted to 145.4 g, the introduction of water at the rate of 45 t/ha provided an increase in root mass by 7.80 g, the introduction of 25 t/ha of organic fertilizer – by 21, 30 g, 35 t/ha – 37.65 g, 45 t/ ha – 45.35 g, 55 t/ha – 61.15 g, 55 t/ha of Effluent + N90P90K90 – 85.35 g and application of mineral fertilizer only (N90P90K90) – by 67.05 g. The high total (99.23 t/ha) and saleable yield (84.19 t/ha) was obtained in a hybrid of Kestrel F1 beet under the use of bioorganic fertilizer Effluent at the rate of 55 t/ha combined with mineral fertilizers (N90P90K90). This result is 9.16-36.70 and 7.65-49.07 tons more than the control variant (without fertilizers and watering). Conclusions. Optimization of provision of macro- and microelements of carrot and red beet plants, due to the application of fertilizers provides an increase in the diameter of the root of carrots and beets. Most actively roots and aboveground part of the carrot plant were formed under application of the bioorganic fertilizer Effluent at the rate of 55 t/ha in combination with mineral fertilizer (N90P90K90). The ratio between aboveground and underground parts of the plant was 1 to 0.38, the total yield of carrot roots – 35-19.28 t/ha and marketability – 12.04-29.24 t/ha (15.04- 26.23%). The general productivity of beet made up 99.22 t/ha, of saleable quality – 86.23 t/ ha, which is 9.75-36.68 and 8.68-49.11 tons more than the control variant (without fertilizers and watering). The variants without fertilizers showed the highest percentage of cracked and affected by diseases roots. The use of bioorganic fertilizer Effluent provided an increase in root weight by 22.7-85.3 g compared to the control variant.
