INFLUENCE OF THE QUANTITY OF TECHNOLOGICAL OPERATIONS FOR THE PROCESSING OF LYCERNY IN THE CUTTING ON ITS CHEMICAL COMPOSITION
Zhurenko Yuri – PhD, Associate Professor of the Department of Agricultural Machines of the Vinnytsia National Agrarian University (3, Solnychna str., Vinnytsia, Ukraine, 21008, е-mail: jurenko@vsau.vin.ua).
The chemical composition and nutritional value of alfalfa hay are influenced by: climatic conditions, soils, phase of development in the period of mowing mass, variety, technology of cultivation and harvesting, etc. Hay harvesting is associated with high nutrient losses due to leaf loss and inflorescence or significant energy consumption for artificial drying. Mechanical losses often exceed 40% or more, with more than half of them occurring in the field operations: mowing, flattening, stirring, raking and weight gain.
The question of the impact of the multiplicity of technological operations on the processing of the roll by elastic working bodies when harvesting hay from alfalfa on the chemical composition has not been sufficiently studied, which was the purpose of the research.Field technological experiments were carried out on pure crops of alfalfa of the blue Vinnychanka variety in different weather conditions. The results obtained by us in the field technological experiments show that the multiplicity of cultivation of the roll in the process of harvesting alfalfa for hay and weather conditions to some extent affect its quality and nutrient content in it.
Thus, the protein content in the initial mass (first experiment) was 15.61, in the hay prepared without the use of roll processing - 13.43, using a single treatment - 14.81, twice - 13.69 and three times 13.65% in dry matter.According to the results of the research, it was found that the hay harvested using single roll processing had the highest carotene content in natural mass - 32.4 mg / kg in the first and 30.4 mg / kg in the second experiments.No significant difference in the variants of experiments was observed in the content of ash and minerals, calcium and phosphorus. By all indicators of nutrient content, the technology of hay harvesting with the use of one-time processing of the roll per day was the best.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
