Abstract
Effect of tow or three week potassium depression on nutrient contents in two rice varieties, Jinheung (a leading local) and IR 667-Suwon 214 (high yielding tropical line), was investigated at various growth stages in water culture system for the nutritional elucidation of potassium top dressing. According to potassium content, potassium ratio beween leaf blade and leaf sheath plus culm, relative potassium content (
