Abstract


Jerusalem artichoke is a plant native to North America, having numerous features from the agronomic point of view, such high growth rate, good tolerance to frost, drought and poor soil, strong resistance to pests and plant diseases and very low requirements related the fertilizers. Usually, Jerusalem artichoke has been used for food or animal feed, but due his chemical compounds it starts to be used for the production of functional food ingredients such as inulin, oligofructose and fructose. The biomass is considered a rich source of ethanol and the production of biogas from Jerusalem artichoke is much higher compared to other energy crops. The variety is one of the main factors of technology, the cultivation of a variety should be done only after a prior test on its adaptability to natural environmental factors. In this paper we present the behavior of 4 tested variety of Jerusalem artichoke cultivated in the conditions of the argic chernozem from the Caracal Plain. The most valuable variety proved to be Olimp, which generate o biomass production of over 49 tons/ha, followed by Rareș variety with 43 tons/ha.
