Plant nutrition one of the most important factors that increase plant production. Thus, the present study was carried out to investigate the effects of NPK (three main macro elements of fertilizer) and their interactions on morphological and biochemical contents of Deodeok (Codonopsis lanceolata). Results exhibited that application of different fertilization treatments had a considerable effect on the different vegetative growth characteristics of C. lanceolata compared to the non fertilizer control. Plant height showed significant results towards all fertilization group compared to non fertilizer group, and the highest value (266.8 cm) for plant height was observed from the N+P+K group. The growth of internode was converted to vine after node 5, no fertilizer effects were found on internode elongation. Chlorophyll content showed a high amount in the range of 42.8 to 46.6 against all fertilization treatment groups, except P+K group. The highest values (57.0 g) for the fresh weight of roots were obtained from the N+P+K groups compared to non fertilizer group. The mineral nutrient content of Na, Mg, Cu and Al of the roots of C. lanceolata showed the lowest amount from in P+K groups compared to other groups. In addition, P from N+K group, Mn from N+P group and Ca, Fe, Zn from N+P+K group also exhibited the lowest mineral content compared to other groups respectively.
