ABSTRACT
This paper presents calculations of the economic indicators of the researched elements of the cul-
tivation 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, 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.

Efektywność ekonomiczna wykorzystania pofermentu z biogazowni na Ukrainie przy uprawie roślin rolniczych jako sposób na osiągnięcie celów Europejskiego Zielonego Ładu

W artykule przedstawiono obliczenia wskaźników ekonomicznych badanych elementów technologii uprawy kukurydzy na zboża i warzywa na Ukrainie, które wskazują, że uprawa tych roślin jest opłacalna we wszystkich wariantach doświadczenia. W badaniach ustalono, że wzrost efektywności ekonomicznej produkcji tych roślin przy zastosowaniu różnych dawek nawozów osiągany jest dzięki bardziej znaczącemu pozytywnemu efektowi wzrostu produktywności w porównaniu z dodatkowymi kosztami związanymi ze stosowaniem tych praktyk rolniczych, a dodatkowe koszty spowodowane stosowaniem nawozów zwracają się wielokrotnie. Udowodniono, że stosowanie nawozów mineralnych i ich łączenie z wysokimi dawkami nawozu bioorganicznego (pofermentu) przy uprawie roślin rolniczych sprzyja zwiększeniu produktywności. Dopracowano teoretyczne i praktyczne zapisy dotyczące ekologicznego problemu unieszkodliwiania odchodów zwierzęcych, w szczególności ferm trzody chlewnej i gospodarstw rolnych, tj. dostarczania nawozów organicznych zapewniających wzrost plonów oraz poprawę jakości zbiorów rolniczych, tak aby podczas utylizacji odpadów zwierzęcych możliwe było uzyskanie wysokiej jakości roślin i warzyw. Zaproponowane podejście do ekonomicznej oceny technologii uprawy kukurydzy na ziarno i buraka ćwikłowego w zależności od systemu nawożenia umożliwia zwiększenie poziomu produktywności upraw rolniczych i warzywniczych przy efektywnym wykorzystaniu nawozów bioorganicznych we współczesnych warunkach gwałtownego wzrostu kosztów nawozów mineralnych.
