Krychkovskyi V. Yu. The efficiency of the biogas stations digestate use in corn, carrots and red beets cultivation under the conditions of the right-bank Forest-Steppe. – It is a qualifying scientific work on the rights of the manuscript.
The thesis on acquisition of the Philosophy Doctor scientific degree in a specialty 201 – Agronomy. Vinnytsia National Agrarian University, Vinnytsia. 2022.
The thesis outlines a theoretical generalization and a new solution to the scientific problem – increasing the yield and quality of corn, carrots and red beets, which is to improve the fertilizer system through the use of the latest organic and mineral fertilizers. It was highlighted the relevance of the theme, the relationship of the work with scientific programs, plans, topics, goals and objectives of research achieved through the justification of the effectiveness of the macro-and micronutrients optimal balance when using bioorganic fertilizers (digestate) in modern technologies for growing corn, carrots and red beets under the conditions of the right-bank Forest-Steppe of Ukraine, which
ensures their high yield and product quality.
The methodology of this research determined the possibility of using bioorganic fertilizers (digestate) to provide plants with macro- and micronutrients to increase soil fertility in the cultivation of corn, carrots and red beets.
Scientific novelty of the obtained results. For the first time in the central part of the right-bank Forest-Steppe of Ukraine the peculiarities of cultivation and development of corn, carrots and red beets, patterns of formation of productivity of these crop hybrids depending on application of various rates of bioorganic fertilizer Efluent and application of mineral fertilizer at the rate of N90P90K90 per 1 ha were established; modern trends in improving the processes of formation of corn, carrot and red beet yieldsin the technology depending on growing conditions and fertilizer were experimentally substantiated; correlations between hydrothermal conditions and yields, as well as between factors of cultivation methods and plant productivity were established; the impact of bioorganic fertilizers on fertility indicators and agrochemical composition of soil was assessed; microbiological analysis of bioorganic fertilizer Efluent was performed; the evaluation of quality indicators of vegetable products under the conditions of bioorganic fertilizer Efluent and mineral fertilizers application was carried out.
It was improved the fertilization system of corn, carrots and red beets in modern cultivation technologies.
Acquired further development: the scientific provisions to increase the productivity of corn, carrots, red beets by using new types of organic fertilizers with positive microbiological and agrochemical properties (Efluent), which were obtained on the basis of anaerobic digestion of pig manure in a biogas station.
Practical value of the obtained results. The main provisions of the work are the basis of methodological recommendations: Improvement fertilization system of corn, carrots and red beets through the use bioorganic fertilizer based on digestate of biogas stations Efluent (2022). Two utility model patents were obtained: Method of obtaining bio-organic fertilizer “Efluent”: Pat. UA 143498 U of Ukraine and Bioorganic fertilizer “Efluent”: Pat. UA 144732 U of Ukraine.
The works of domestic and foreign scientists on the physiological role of macro- and microelements for the cultivation of corn, carrots and red beets, regarding the peculiarities of using new organic fertilizers obtained by digestion of livestock and crop wastes in biogas stations have been analyzed.
Key words: digestate, carrot, corn, red beets, root crop, grain, bioorganic fertilizers, nutrition system, yield, biometric indicators, marketable products, leaf surface.
