Abstract
Studies were conducted to investigate the varietal difference of nutrient absorption between a Japanese variety Norin No. 29 and a Korean variety Nongkwang. The rice plants were cultured in the normal soil (Konosusoil), humus-rich soil (Matsuo soil), and poor sandy soil (Oami soil). From the experiment, the following differences were found. 1. No difference was observed in the nitrogen and phosphorus absorption. 2. There was a difference in nutrient absorption between the two varieties when planted in the humus-rich soil under reduced condition. Potassium and silica contents in Nongkwang were higher than those in Norin No 29.
