The aim of the research was to determine the content of some components (dry matter, ash, harmful, reducing sugars) in sugar beet roots, which were cultivated by traditional, conservation and no-tillage methods with two levels of herbicide protection. A strict field experiment was realized in 2004–2007 at the Plant Breeding Station of Sugar Beet Breeding Company in Straszków near Kłodawa. It was found that the level of herbicide protection influenced reducing sugars content in roots. The smaller level of protection, the more reducing sugars beet roots contained. The tillage systems affected the content of ash and harmful nitrogen in the roots. Among conservation tillage systems used, the most of the ash was found in the roots collected from the plots where only the stubble crop was cultivated. On the other hand, the least harmful nitrogen content was found in roots grown on straw mixed crop cultivator and no-tillage system. The most of harmful nitrogen was in the roots grown with the forecrop straw and stubble crop left behind by the spring with intensive protection. The best technological value was observed for the roots collected from no-tillage system with intensive herbicide protection.
