This study was conducted to investigate the effect of the salinity on growth, inorganic ion content, and photosynthetic rate (P∧N) in Korean ginseng (Panax ginseng C.A. Meyer) with complex fertilizer (CF) and NaCl concentrations. The salinity was applied to plant using NaCl and CF, and controlled an EC as 0.0, 1.0, 2.0 and 3.0 dS m-¹. The salinity treated three times at 35, 42 and 49 d after transplanting. The leaf area in different electrical conductivity (EC) decreased only the higher NaCl 1.0 dS m-¹. The root growth increased with CF and especially, it was two times higher at 3.0 dS m-¹ than that of control.
