Kvalita cukrovky a možnosti jejího ovlivnění
Stávek, Ondřej
The aim of this bachelor thesis was to conduct literary research into the quality of sugar beet. Part of it was also an experiment focused on testing of the off-root impact on the quality of production. Root growths including the changes of its technological quality were observed here as well. Tuber growth during vegetation corresponded well with the current weather conditions. The amount of sugar content in tubers gradually increased up to the average harvest value of 18,1 %. The volume of alfa-aminonitrogen during observation did not significantly change and its value remained between favourable 15 - 20 mg/100g. Low content of harmful potassium during the harvest was pleasing too. The best results were achieved via repeated application of Carbonbor Si fertilizer. This option brought about the highest tuber production, polarized sugar production including the highest raffinade per acre. The highest sugar volume was achieved by repeated application of Carbonbor Zn, Cu, S fertilizer with the combination of Insenol agent. The research showed that off-root nutrition supports tuber yield and has a positive impact on its technological quality.
