In the three-year field trials the effect of ecological cultivation of table potatoes (in comparison with conventional cultivation) on the selected factors of tuber quality was estimated. Trials were performed at two localities in the Czech Republic with seven varieties. Based on the statistical evaluation it is evident that the ecological cultivation positively affected nitrate and reducing sugar content. In ecological variant the nitrate content was by 11% lower and reducing saccharide content was by 22% lower as compared to conventional option. Contrary a negative effect of ecological cultivation was determined in total polyphenol content (by 10.2% higher) and yields per ha (by 36% lower). Cultivation method did not significantly affect the dry matter content and glycoalkaloid content.
