内容 1.落花生の稔実と石灰施用量との関係について圃場試験と水耕法とで試験した.圃場試験は置換性石灰を乾土100gにつき1.4mg当量含む埴壤土で昭和27年と28年に反覆して行った.両試験共石灰の施用量が乾土100gにつき10mg当量の場合が落花生の稔実に最も効果が大きかった.水耕法の場合には結実圏に石灰のない砂を用い, これに種々の量の石灰をまぜ, 適湿を保たせるようにした.砂100g当り3mg当量の石灰を結実圏に添加した場合が空莢率が最小で収量が著しく増加した.2.落花生の稔実に対する4種の石灰化合物すなわち消石灰, 塩化石灰, 硫酸石灰炭酸石灰, の効果を比較試験した.消石灰が稍々劣った外は各化合物が略同じ効果を示した.
1. Experiments were practised on relation between level of calcium application and peanut fruit filling by means of field trial and water culture. Field experiments were repeated in 1952 and 1953 on silty loam soil containing 1.4 me exchangable calcium per 100 grams. On both tests, level of application of 10 me calcium per 100 grams dry soil was the most effective on the peanut fruit filling. In the water culture, calcium free sand was used as fruiting zone, mixed with various levels of calcium and kept to be suitable moisture. The least percentage of unfilled pods and marked increase in yield were obtained, where the amount of 3 me calcium per 100 grams sand was added in fruiting zone. 2. Experiment was carried out to compare the effect of four calcium compounds, such as calcium hydroxide, calcium chloride, calcium sulfate and calcium carbonate, for peanut fruit filling. All of the calciun compounds were found to be approximately equal in value, except the calcium hydroxide was liltle inferior to others.
