Background: The roots of Atractylodes macrocephala Koidzumi contain atractylone, which is used to suppress appetite and indigestion caused by gastrointestinal disturbance. The present study was conducted to investigate the effect of several organic compost on the growth and root yield of A. macrocephala with organic fertilizer.Methods and Results:When organic fertilizer was applied basally, the average yield of 10 a was 184.6 ㎏ in the HA (Hwanggeumjidae, organic material mix), 171.3 ㎏ in the GG (Gyunbaeyangchegreen, bacterial cuture filtrate) and 175.0 ㎏ in the CF (Customary fertilization, control) each other in practice of CF had no statistical significance. Atractylenolide I was significantly greater in the HA (0.036%) than the GG (0.034%) or CF (0.023%). With regard to the amount of organic fertilzer, 10 a yield ws the most common of 203.0 ㎏ at 2.0 times of the organic 1 (HA), conventional fertilization of 134.0 ㎏ and 173.0 ㎏ of no application was a statistically significant. Organic fertilizer 1 was 1.5 to 2.0 times, organic fertilizer was 2 to 1.5 times that were most suitable.Conclusions:The results of the present study indicated that HA and GG are the most suitable for the organic cultivation of A. macrocephala. The content of atractylone I was highest under the HA treatment and lowest under the CU (Chamjoa, oil cake), TG (Totogreen, plant oil cake) and HG (Heuksalgreen, Castor oil cake) treatment.
