Summary: 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 coefficients of energy efficiency were also observed in the variants with the simultaneous application of mineral fertilizers (N90P90K90) 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.
