Investigation of the agronomic qualities of Jerusalem artichoke (Helianthus tuberosus L.) was performed upon chernozem (rich soil), anthropogenized black sand (medium-rich soil) and anthropogenized brown sand (poor soil). Jerusalem artichoke is found to have distinct advantage, especially in poor soil, regarding the yield of carbohydrates per unit of area, compared with the usual field farming crops (maize, sugar beet, potato, sorghum). In the rich soil a 2.7 times higher yield of carbohydrates, compared with potato, and about 2 times higher one, compared with maize was achieved. The investigated varieties differ notably among themselves by the yield of tubers and carbohydrate content. This species is a good raw material for the production of alcohol. In order to obtain alcohol it is possible to perform hydrolysis in the acid medium, at higher temperatures, or with the application of corresponding enzymic preparation. In case that Jerusalem artichoke is used, building of a system of small-capacity (10-20m of alcohol a day) sections for the production of alcohol is appropriate. This species can be used as raw material for the production of high-fructose syrup and crystal fructose.
