Abstract: Our study was designed to compare chemical composition changes of different Jerusalem artichoke tubers cultivars during the vegetation period and to identify the period when they mostly accumulate useful materials. In 2013 there were examined „Albik“, „Rubik“ and „Sauliai“ cultivars of Jerusalem artichoke tubers which were grown in an organic farm in Varėna district. In Aleksandras Stulginskis University with standardized methods there were established their chemical composition during the spring and autumn periods of vegetation. It was established that the dry matter content of Jerusalem artichoke tuber during spring development vegetatitive period decreases as well in autumn – increased. Highest amount of dry matter has accumulated 'Albik' in tubers in spring vegetetative period (24.3%) and in the autumn vegetative period (25.3%). Highest content of crude protein has accumulated in 'Sauliai' tubers in spring vegetetative period (10.7%), in autumn vegetative period (11.8%), as well in 'Rubik' tubers highest amount of crude ash established in the spring vegetetative period – 13.5%, and in the autumn vegetetative period – 8.9%
