Abstract
The literature is relatively poor in data on the fertilization of Jerusalem artichoke and especially the optimization of this technological stage which is not always correlated with the nutritional space of plants in order to obtain higher amount of fresh biomass or tubers. Although Jerusalem artichoke is promoted as a crop with low requirements for soil fertility, it reacts very well to both types of mineral fertilization and especially on applied organic fertilizer. In this paper we highlight the main levels of mineral fertilization corelated with plant’s density which show us that in the tested conditions of argic chernozem from ARDS Caracal we obtained the most valuable yields of fresh biomass at variant where we applied N120P120K80 in the conditions of 50 cm between plants/row. The highest level of fresh biomass was 55.1 t/ha and the underground tubers production was almost 28 t/ha
