The subject of the experiment were two domestic population of marshmallow originating from Backi Petrovac and Pancevo (Serbia). The experiment was performed using the split-split-plot method with four repetitions, and tested fertilization with different quantities of nitrogen fertilizer (control, 50, 80, and 120 kg N /ha), spacing between plants in row (20, 30, 40 and 50 cm) with the same inter-row spacing of 50 cm, and reproduction (direct sowing in the field, production of seedlings in hotbeds and tranplatation). In case of both varieties, the maximal yield of natural root, raw peeled root and drug were obtained in both years of cultivation on a control plot, that is, on a plot that was not treated with nitrogen fertilizer. The maximum plant density (100,000 plants/ha), gave maximal yield in case of both tested varieties of marshmallow and with all variants of fertilization. During the first year of cultivation, the method of direct sowing has resulted in a significantly higher yield in comparison to the case where transplantation was applied, however that difference disappeared in the second year of cultivation. During the first year of cultivation, the content of mucilage (that is, the number of swellings) was extremely high - over 25, during the second year, it was between 20-25.
