Abstract

The influence of variety and foliar applications of Atonik and Polybor 150 on root yield and inulin content in root of chicory (Cichorium Intybus L.) plant were observed in field polyfactorial experiment. The field trials were established on experimental station Dolná Malanta in warm maize production area in 2005 and 2006 years. The root yield and inulin content were statistically high significantly influenced by year’s weather conditions. In term of obtained root yield and inulin content in root the combination of foliar preparations on variant B (Atonik: 0.4 l ha-1 in 2nd post-emergence herbicide application; Atonik + Polybor 150: 0.6 + 2.5 l ha-1 in 3rd post-emergence herbicide application; Polybor 150: 2.5 l ha-1 in 1st fungicide treatment) was shown to be optimal in given agri-ecological conditions. Biological material affected the formation of yield parameters very differently. The highest yield of root was observed at variety Fredonia Nova and inulin content in root at variety Maurane (both statistically significant).
