Abstract: The two factors experiment was carry out in Aleksandras Stulginskis University in 2015–2016. Jerusalem artichoke tubers of three variety „Sauliai“, „Albik“, „Rubik“ were grown in the Petras Tinkevičius ecological farm in 2015. A factor – different controlled atmosphere chambers: 1 chambers – CO2 – 10%, O2 – 3,5%, N – 88%, temperature ±2 oC, relative humidity 90–95 %; 2 chambers – CO2 – 15 %, O2 – 5 %, N – 80 %, temperature ± 2oC, relative humidity 90–95 %; 3 chambers – CO2 – 1 %, O2 – 21 %, N – 78 %, temperature ± 2oC, relative humidity 90–95 %; B factor – storage duration: after harvesting, after 4, 8 and 12 weeks. During storage period there were determined systematically, using standard methods: natural weight loss, quantity of potassium in Jerusalem artichoke tuber‘s. The least amount of weight losses during the experiment in „Sauliai“ and „Albik“ Jerusalem artichoke tubers where achieved in the first controlled atmosphere chamber (CO2 – 10 %, O2 – 3,5 %, N – 88 %). In „Sauliai“ tubers the losses were – 1.99 % and in „Albik” – 3.49 %. The biggest weight loss was noticed in the third controlled atmosphere chamber (CO2 – 1 %, O2 – 21 %, N – 78 %). In „Sauliai“ tubers the losses were – 7.47 %, and in „Albik” – 7.46 %. In “Rubik” artichoke tubers the results where opposite. The least amount of natural weight losses – 3.39 % were noticed in the third controlled atmosphere chamber (CO2 – 1 %, O2 – 21 %, N – 78 %). The biggest natural weight losses – 12.13 % were noticed in the first controlled atmosphere chamber (CO2 – 10 %, O2 – 3.5 %, N – 88 %). In „Sauliai“ tubers the statistically biggest amount of potassium was noticed in the second controlled atmosphere chamber (CO2 – 15 %, O2 – 5 %, N – 80 %) and after four weeks storage the amount contained was – 288.23 mg 100 g-1. The statistic amount after harvesting was – 186.37 mg 100
