Abstract

The Jerusalem artichoke (Helianthus tuberosus) is considered a species with relatively high tolerance to water stress and very high adaptability to extremes of unfavorable factors - drought resistance, at extremely high temperatures (350- 450C the plants and -300 -450C the tubers). The tubers with high inulin content are formed on the root branches and are increasingly used as food for patients with diabetes. The variety is one of the main factors of the technology, the cultivation of a variety should be done only after a preliminary test regarding its adaptability to the natural environmental factors. On the sandy soils from Dabuleni were studied the varieties Dacic, Olimp, Rustic and the local population Dăbuleni. It was noted by the number of tubers/plant the Olimp variety with 60.4 stems/plant, and the highest weight of a tuber was recorded in the Rustic variety (51.6 g/tuber). The highest production was made at the Olimp variety, respectively 70.03 t/ha, corresponding to the largest number of tubers harvested at a plant, followed by the production of the Rustic variety of 51.97t/ ha. At the Dacic variety, 15.6 t/ha were obtained, and the local population of Dăbuleni achieved the lowest production (6.45 t/ha). The inulin content was between 12.49% in the Rustic variety and 14.47% in the Olimp variety. Dacic varieties and local population Dăbuleni were highlighted by high in total dry matter, soluble dry matter and soluble carbohydrates, and Rustic varieties and local population Dabuleni were high in vitamin C content (14.92-14.96 mg).
