Organic and/or mineral fertilizers significantly influence phenolic profile of chicory. In general more phenols were found in chicory that was fertilised with organic fertilisers. Fertilizer administration provides a discriminant classification of the chicory cultivars according to their phenolic compounds.

The chicory roots were forced in the dark in three fertiliser solutions enriched in nitrogen (N), phosphorus (P) and/or potassium (K) (i.e., N/P/K, N/P, N alone), each applied at 10, 20 and 30 g/L. Under different nutrients, 44 phenolics were extracted from five chicons cultivars. The phenolics varied widely among analysed hydroponically forced chicons, phenolics profiles are influenced by cultivar and forcing nutrient solution.

The aim of the present study was to evaluate the fatty-acid composition of five chicory cultivars (red, red-spotted, green) produced as cultivated organically, conventionally) chicory leaves/ heads and as forced chicons. The present analysis demonstrates that the majority of the fatty acids in chicory and chicon consist of the PUFAs, among which the main ones are a-linolenic acid (C 18:3, n-3) and linoleic acid (C 18:2, n-6). The fertilizers significantly impact fatty acid formation.

The applicability of stable isotope and multi-element data for determining the geographical origin of fresh apple juices made from three apple cultivars (Idared, Golden Delicious and Topaz) was examined. Study included the following parameters: δ2H and δ18O content of juice water; δ15N and δ13C content of the pulp, (D/H)I and (D/H)II in ethanol and the concentration of S, Cl, Fe, Cu, Zn and Sr. Parameters δ2H and δ18O content of fruit juice water; the δ13C and (D/H)I content of ethanol as well as the concentration of S, Mg, K, Cu, and Ti best distinguished the different types of cultivar.

Study deals with various aspects of cover crop usage in organic vegetable production. Cover crops can reduce the use of external inputs such herbicides and pesticides. In a review examples of cover crop’s effects to pest populations and diseases are summarized. Among most important benefits, cover crops suppress weeds as well as improve and maintain soil fertility.
