One of the aims of the dissertation thesis was to evaluate the dynamics of changes in the sugar beet quality during the growth and development with respect to different agro-ecological conditions on small-plot experiments in the years of 2010 and 2011. The possibilities of foliar nutrition application were proved on yield and technological parameters of sugar beet (digestion, soluble ash, alpha-amino nitrogen). Another objective was to assess the dynamics of yield and changes in the technological quality of sugar beet during the growing season in Central Moravia carried out in the cooperation with the sugar factory called Vrbátky. In the monitoring, the data were evaluated from the years of 2005 - 2011. The monitoring was carried out in the second half of sugar beet growth, as sugar factories normally prove in the country. The conditions for the growth and development of sugar beet and its technological quality were better in the year of 2010 than in 2011. The highest weight of tops was reached with the use of spray fertilizer called Magnitra L for the variants with within small plot experiments. The highest root weight showed sugar beet harvested after the application of Carbonbor K. The highest sugar content proved the tubers after the fertilization with Bortrac. The content of soluble ash was observed after the application of Magnitra L. Dangerous nitrogen content was low in all variants. Sugar beet was mature. In 2011, the highest leaf area of sugar beet was found out using the spray called Carbonbor K. The highest root weight was determined in the variant with Carbonbor K spray. The highest sugar content proved the tubers after the fertilization of Carbonbor K and Carbonbor Na. The content of soluble ash and harmful nitrogen was higher than in 2011. In the monitoring, the following dependences were proved: Weight tops decreased during the vegetation. On the average of the years, a weight lowered from 980 g/plant to 450 g/plant. The root reached from 640 to 900 g /plant as well as sugar content increased from 14, 26 to 15.8 %. Significant differences were found out between the years.
