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: firstname.lastname@example.org).
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.
