Alpha-amine nitrogen content and alkalinity characteristics of sugar beet parental lines and F₁ hybrids

Modern agricultural production is faced with the need to increase the yield and quality of agricultural crops. For sugar beet, the key factors determining the yield and quality of root crops are the content of alpha-amine nitrogen and the alkalinity of sugar beet roots. These parameters have a significant impact on plant metabolism, growth and development, which affects the productivity and quality of the crop. The goal of the research is to analyze the concentration of alkalinity and the content of alpha-amine nitrogen in sugar beet roots. The objective is to determine the content and effect of alpha-amine nitrogen and alkalinity on sugar beet roots. The Research methods. The studies were conducted in the field and laboratory conditions. Detailed experimental schemes were developed. Statistical analysis of the results was performed as part of the study. The Results. The comprehensive analysis included an assessment of alkalinity and alpha-amine nitrogen content in sugar beet roots. In 2023, the alkalinity index varied in the range of 1.31-3.59 mg-eq/100 g. In 2024, there was a slight increase in alkalinity to 1.54-3.73 mg-eq/100 g. High content of alpha-amine nitrogen negatively affects the process of sugar formation in sugar beet roots, so this indicator requires special attention and study in parental forms and F1 hybrids of sugar beet. In the course of the analysis, a relationship between the alkalinity level and the content of alpha-amine nitrogen, which determines their impact on sugar beet roots has been established. Conclusion. The quality indicators of sugar beet roots deteriorate due to an increase in the concentration of alkalis and alphaamine nitrogen, which is most clearly seen in dry years. According to the results of statistical processing, the greatest impact (20.5%) on the alkalinity indicator was achieved with the combined action of three components (Year x Genotype x Background), and alpha-amine nitrogen was affected by a combination of factors - Year x Genotype and amounted to 27.8%
