| Experiments were conducted to estimate optimal potassium strength in the nutrient solution for ¡®Nokgwang¡¯and¡®Kwari¡¯green pepper seedlings cultured in small plug-cell trays. Plant height, stem diameter, and leaf area increased with increasing K concentration, with greater effect on ¡®Kwari¡¯ than ¡®Nokgwang¡¯. Total dry weight increased by increasing potassium strength.¡®Kwari¡¯had heavier dry weight than ¡®Nokgwang¡¯Chlorophyll content differed by cultivars and potassium strength. The highest chlorophyll content was obtained at 2.0 strength potassium in¡®Nokgwang¡¯, but not in¡®Kwari¡¯Net photosynthesis was greater in plants fertilized with 1.5 strength potassium for¡®Nokgwang¡¯and 2.0 strength potassium for ¡®Kwari¡¯than the other treatments. |
