The contents of nitrogen, potassium, phosphorus, calcium, magnesium and sodium were estimated in tubers of Jerusalem artichoke Helianthus tuberosus coming from the field experiment conducted over 2003-2005. The experimental factors were the cultivars of Jerusalem artichoke Albik and Rubik and different nitrogen fertilization levels, against phosphorus and potassium fertilization and the full dose of manure. The cultivar Rubik proved to be more abundant in mineral elements than Albik. The latter was cha-racterized by a higher stability of characteristics. The highest content of nitrogen, calcium and sodium in Jerusalem artichoke tubers was found at the plots fertilized with a dose of 50 kg N·ha^-1.
