the plants. However, influence of the grown locality, climate conditions and way of cultivation belong to important external factors. In our experiment the influence of different nitrogen doses (0 - 40 - 80 - 120 - 160 - 240 kg N.ha<sup>-1</sup>) applied in the form of Vermikompost on the total polyphenol content and derived total antioxidant activity in cv. Sorento were investigated. While in the 1<sup>st</sup> - 5<sup>th</sup> variants the determined polyphenol content in dry mater of potato tubers decreased from 399.2 to 70.40 mg.kg<sup>-1</sup>, in the 6<sup>th</sup> variant that was twice higher in comparison to the 5<sup>th</sup> variants (135.6 mg.kg<sup>-1</sup>).

The study also confirmed a strong statistical correlation between the content of polyphenols and the content of antioxidant activity has been confirmed <br /> (sign. F: 3.24E<sup>-10</sup>). The highest value of antioxidant activity was observed in the first variant. From the first to the fifth variant (7.62 - 4.84%), the value of antioxidant activity was decreasing and in the sixth variant this value increased to 6.31%.</span><strong><span style="font-size:10.0pt;line-height:115%;mso-ansi-language:EN-US" lang="EN-US"></span></strong></p></div></td></tr></tbody></table></div> <!--EndFragment--> |

the plants. However, influence of the grown locality, climate conditions and way of cultivation belong to important external factors. In our experiment the influence of different nitrogen doses (0 - 40 - 80 - 120 - 160 - 240 kg N.ha<sup>-1</sup>) applied in the form of Vermikompost on the total polyphenol content and derived total antioxidant activity in cv. Sorento were investigated. While in the 1<sup>st</sup> - 5<sup>th</sup> variants the determined polyphenol content in dry mater of potato tubers decreased from 399.2 to 70.40 mg.kg<sup>-1</sup>, in the 6<sup>th</sup> variant that was twice higher in comparison to the 5<sup>th</sup> variants (135.6 mg.kg<sup>-1</sup>). The statistically significant differences in values of total polyphenol content between variants (polynomial function of 2<sup>nd</sup></span><span class="hps"><span style="font-size:10.0pt;line-height:115%; mso-ansi-language:EN-GB" lang="EN-GB"> degree</span></span><span style="font-size:10.0pt;line-height:115%;mso-ansi-language:EN-GB;mso-bidi-font-weight: bold" lang="EN-GB">) were confirmed. The study also confirmed a strong statistical correlation between the content of polyphenols and the content of antioxidant activity has been confirmed <br /> (sign. F: 3.24E<sup>-10</sup>). The highest value of antioxidant activity was observed in the first variant. From the first to the fifth variant (7.62 - 4.84%), the value of antioxidant activity was decreasing and in the sixth variant this value increased to 6.31%.</span><strong><span style="font-size:10.0pt;line-height:115%;mso-ansi-language:EN-US" lang="EN-US"></span></strong></p></div></td></tr></tbody></table></div> <!--EndFragment-->http://www.potravinarstvo.com/journal1/index.php/potravinarstvo/article/view/305potatopolyphenolantioxidant activitynitrogen fertilization |
