Abstract

V današnjih časih so kupci vedno bolj zahtevni in na trgu je vedno večje povpraševanje po kakovostni hrani. Zato mora pridelovalec znati pridelati kakovostno hrano, če hoče biti zanimiv in konkurenčen na trgu. S pravilno tehnologijo pridelave in ukrepom, kot je gnojenje, lahko vplivamo na količino in kakovost korenja. V nekaterih poizkusih se je izkazalo, da imajo na količino in kakovost korenja poleg gnojenja vpliv tudi podnebni dejavniki, kot so temperatura, padavine in sončno sevanje ter fizikalne in kemijske lastnosti tal. Dodajanje dušičnih gnojil v tla ali foliarno vpliva na povečanje količine pridelka in višjo vsebnost sladkorjev v korenju. Večji odmerki dušičnega gnojila vplivajo na višjo vsebnost karotenoidov in fenolnih spojin, medtem ko se vsebnost vitamina C zmanjša. Različni odmerki kalijevega gnojila ne vplivajo na kakovost korenja. Pri poizkusu, v katerem so spremljali vpliv bora (B) in kalcija (Ca), so ugotovili, da je korenje vsebovalo več karotenoidov, vitamina C in fenolnih kislin, tudi v primeru dodanih nizkih koncentracij bora.

Secondary title: Effect of fertilization on yield in the content of selected primary seconadry metabolites in carrots (Daucus carota L.
Secondary abstract: The demands of modern consumers are higher than before, and consequently, the demand of the market for quality food is increasing. Therefore, producers must know how to produce quality food in order to be competitive. Proper production technology and measures such as fertilization can influence the quantity and quality of carrots. Experiments were made which proved that not only fertilization, but also climatic conditions, such as temperature, precipitation, solar radiation and physical as well as chemical properties of the soil affect the quantity and quality of carrots. Soil and foliar fertilization with nitrogen increased yield and sugar content in carrots. Higher amounts of nitrogenous fertilizers increased the content of carotenoids and phenolic compounds in carrot, but decreased the content of vitamin C. Different fertilization regimes with potassium had no significant effect on carrot quantity. Additionally, an experiment monitored the influence of boron (B) and calcium (Ca) on the content of carotenoids, vitamin C and phenolic acids in carrots. The results indicated that all these parameters were increased in treatments, in which even small amounts of B were added
