| Description
| - The objective of several years of field experiments was to explore the changes in the total polyphenol and ascorbic acid content, as important antioxidants, in potato tubers at various levels of N, P, K and Mg nutrition. The polyphenol and ascorbic acid content was affected particularly by the weather in the experimental year;the fertilization variants had no significant effect on the polyphenol content. A negative effect on ascorbic acid content in tubers was observed in the case of an increased intensity of N fertilization (at 180 kg N/ha ascorbic acid decrease was lower by 6,1% compared to doses 100 kg N/ha). On the contrary, a favourable effect was determined at increased levels of potassium and magnesium fertilization (at 166 kg K/ha a 60 kg Mg/ha ascorbic acid increase was by 6,2% higher compared to levels 108 kg K/ha and 30 kg Mg/ha).

- Cílem víceletých polních pokusů bylo zjistit změny v celkovém obsahu polyfenolů a kysleiny askorbové, tedy důležitých antioxidantů, v hlízách brambor při různých úrovních N, P, K a Mg hnojení. Obsah polyfenolů a kyseliny askorbové byl částečně ovlivněn průběhem počasí v jednotlivých pokusných letech. Obsah polyfenolů nebyl ovlivněn jednotlivými variantami hnojení. Negativní vliv na obsah kyseliny askorbové byl zjištěn v případě zvýšené intenzity N hnojení (při 180 kg N/ha byl zjištěn pokles v porovnání s dávkou 100 kg N/ha o 6,1%). Naopak hnojení P a Mg mělo pozitivní vliv na obsah kyseliny askorbové (při 166 kg K/ha a 60 kg Mg/ha došlo k nárůstu obsahu o 6,2% v porovnání s dávkami 108 kg K/ha a 30 kg Mg/ha). (cs)
