KATAMBORA) to applied potassium and sodium on a Dark Red soil. The Rhodesgrass plant was grown in the pot, which contained 2.2kg soil, under the greenhouse conditions and cut twice with 40 to 60 day intervals. To each cut, potassium and sodium were applied at a rate of 0.0, 0.2, 0.4, and 0.8g K_2O/pot, and 0.0, 0.2, and 0.4g Na_2O/pot, respectively. On the fresh matter yield of the Rhodesgrass plant, the 1st cut received no effect from applied potassium and sodium. The 2nd cut of the grass increased in the fresh matter by the application of sodium, but it received interaction between the applied potassium and sodium. The effect of potassium and sodium was significant in addition to the interaction of applied these two elements, when the total of the 1st and 2nd cuts' fresh matter was taken into consideration. On the dry matter of the grass, only the interaction of the potassium and sodium applications was found significant in the 2nd cut and in the total of the 1st and 2nd cuts. The concentrations of nitrogen, calcium, and magnesium in the Rhodesgrass plant were not much affected by the application of potassium and sodium. Consequently, the quantity of these nutrient elements absorbed by the grass varied only to a less extent by the treatment with potassium and sodium. The concentration of potassium in the grass was significantly increased by the application of potassium. The increase in the potassium uptake of the grass was also significantly affected by the potassium application, but this increase tended to encounter the interactiom of applied sodium. The concentration of sodium in the Rhodesgrass plant was found to increase significantly by the application of sodium, but to decrease by the application of potassium. The interaction between the potassium and sodium applications was significant. The uptake of sodium by the grass was also significantly affected by the application of potassium and sodium in the similar way to the concentration of sodium. From the results obtained in the present investigation, suggested was that an increase in the yield of Rhodesgrass will be effected by the application of potassium on the Dark Red soil used for this experiment, but the increase may be diminished when the grass is somewhat supplied with sodium. It was further suggestive that sodium, which is considered abandant as air-born salt in Okinawa, may be playing a role in potassium economy in the field, because the potassium absorption of the grass was depressed to some extent when sodium was supplied.","subitem_description_type":"Other"},{"subitem_description":"\u98fc\u6599\u4f5c\u7269\u683d\u57f9\u306b\u95a2\u3057\u6c96\u7e04\u306e\u5404\u7a2e\u571f\u58cc\u306b\u304a\u3051\u308b\u65bd\u80a5\u7ba1\u7406\u624b\u6cd5\u306e\u6539\u5584\u306b\u8cc7\u3059\u308b\u305f\u3081\u5b9f\u9a13\u3092\u884c\u3063\u3066\u3044\u308b\u304c\uff0c\u4eca\u56de\u306f\u6697\u8d64\u8272\u571f\uff08\u901a\u79f0\u5cf6\u5c3b\u30de\u30fc\u30b8\uff09\u3092\u7528\u3044\uff0c\u30dd\u30c3\u30c8\u8a66\u9a13\u306b\u3088\u308a\u30ed\u30fc\u30ba\u30b0\u30e9\u30b9\uff08\u30ab\u30bf\u30f3\u30dc\u30e9\u7cfb\uff09\u306b\u5bfe\u3059\u308b\u30ab\u30ea\u53ca\u3073\u30ca\u30c8\u30ea\u30a6\u30e0\u306e\u65bd\u7528\u304c\uff0c\u30ed\u30fc\u30ba\u30b0\u30e9\u30b9\u306e\u53ce\u91cf\u53ca\u3073\u7a92\u7d20\uff0c\u30ab\u30ea\uff0c\u30ca\u30c8\u30ea\u30a6\u30e0\uff0c\u30ab\u30eb\u30b7\u30a6\u30e0\uff0c\u30de\u30b0\u30cd\u30b7\u30a6\u30e0\u306a\u3069\u306e\u5438\u53ce\u306b\u53ca\u307c\u3059\u5f71\u97ff\u3092\u8abf\u3079\u305f\u3002\u571f\u58cc\u306f\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u9644\u5c5e\u8fb2\u5834\u306e\u6697\u8d64\u8272\u571f\uff08pH6.0,
