Experiments were conducted to investigate optimal ionic salt strength in nutrient solution for small plug seedlings of ¡®Nokgwang¡¯ and ¡®Kwari¡¯ green pepper. Plant height increased with increasing ionic salt strength. total leaf area was 72£¥ greater in ¡®Nokgwang¡¯ and 18% greater in ¡®Kwari¡¯with 2.0 ionic salt strength than that with 1.0 strength. Dry weight per plant tended to increase at higher ionic salt strengths in ¡®Kwari¡¯, but to decrease in ¡®Nokgwang¡¯ Chlorophyll content increased with increasing ionic salt strength in both cultivars. Photosynthetic rate, stomatal conductance, and transpiration rate were higher for plants fertilized with 1.5 strength than other strengths in both cultivars. Photosynthetic rate peaked at 8.74 $mu$mol$.$m$^{-2}$ s$^{-1}$ in ¡®Nokgwang¡¯ and 5.70 $mu$mol$.$m$^{-2}$ s$^{-1}$ in¡®Kwari¡¯with 1.5 ionic salt strength.
