The quality comparison of different Jerusalem artichoke (Helianthus tuberosus L.) cultivars tubers

Abstract

The aim of this study was to evaluate the quality of different Jerusalem artichoke cultivars tubers grown in a Lithuanian ecological farm. Jerusalem artichoke tubers of three cv. ‘Albik’, ‘Rubik’, ‘Sauliai’ were grown in the Petras Tiknevičius ecological farm in 2011. The agrochemical indexes of soil and the chemical composition of tubers have been identified. According to our results, cv. ‘Sauliai’ tubers have been the most productive – the average weight of one tuber was 26.1 g. ‘Albik’ tubers accumulated the highest amount of dry matter and crude protein – 23.21 ± 0.44% and 7.79 ± 0.5% DM, respectively. ‘Rubik’ tubers accumulated the most crude fiber and crude ash – 4.28 ± 0.18% DM and 6.75 ± 0.14% DM, respectively.
