土壤別 肥料선택이 大豆의 增産에 미치는 影響 = Effects of the methods of fertilizer selection in different parent soil on an increased yield of soybean

국문 초록 (Abstract)

母岩을 달리한 風化土壤으로 大豆를 試驗한 結果, 다음 몇가지로 結論을 내리고저 한다.
가. 山淸(花崗岩風化土壤)지역
1. 石灰施用에 따라 시험후 土壤의 P^H가 상승하였으며 石灰單獨施用區보다 石灰, 퇴비시용구가 P^H 7.25까지 교정이 되었다.
2. 石灰施用區가 1株협수의 增加가 현저하였다.
3. 種實중량 成積은 無肥區에 比하여 질소＋石灰＋퇴비시용구가 88.1%의 增收로서 통계적으로 고도의 有意性이 인정되었다.
4. 퇴비와 붕소 施用의 效果는 인정되지 않았다.
5. 石灰의 效果가 질소, 퇴비, 붕소보다 절대적인 效果가 있다.
나. 晋州(水成岩風化土壤)지역
1. 石灰施用에 따라 試驗後 土壤 P^H는 상승하였으나 山淸보다 뚜렷하지 않다.
2. 石灰와 퇴비, 붕소施用으로서 1株협수는 증가된 경향이다.
3. 石灰 單獨效果가 현저하며 무비구에 比하여 75.0% 增水되었다.
4. 퇴비, 붕소의 效果도 현저하며 無肥區에 比하여 질소 單獨區를 제외한 모든 처리구는 1%의 有意性이 인정되었다.
6. 石灰施用으로 土壤內有效인산의 增加가 뚜렷하였다.
다. 山淸과 晋州지역의 비교
1. 山淸보다 晋州地역이 퇴비의 效果가 높고 山淸은 石灰의 效果가 높다.
2. 晋州가 山淸보다 대체로 높은 增收 效果가 있다.

다국어 초록 (Multilingual Abstract)

This work was carried out to establish the experiment on the cultivation of soybeans, using different types developed on different parent rocks.
The results obtained may be summarized as follows.
A. Thearea of San-Chung (Granite soil).
1. Soil P^H was increased with application of lime and soil P^H in the plot of lime and compost application together compared with that of only lime application was also increased to 7.25.
2. In number of pods per a plant, lime application plot was apparently increased.
3. The yield was increased 88.1% in the plot of lime and compost application together compared with that of none fertilizers, and was statistically shown the highly significant.
4. The effect of compost and that of Boron was not shown.
5. Application of lime was shown the largest effect among respective application of nitrogen, compost and Boron.
B. The area of Jinju (Sedimentary soil)
1. Soil P^H was increased with application of lime but was not clearer than that of San-chung.
2. Number of pods per a plant tended to increase with application of lime, compost and boron together.
3. The effect of only lime application was clearly shown and the yield in application of nitrogen and compost together was increased 101.2% as compared to none fertizer plot.
4. The effect of compost application and that of boron application was clearly shown and increased 74.0% as compared to none fertilzer plot.
5. All the treatments was shown 1% in significance excepting only nitrogen application plot compared with none fertilizer plot.
6. Available phosphorus in soil was apparently increased with application of lime.
C. Comparision betwen the area of Jin-ju and that ot San-Chung.
1. The effect of compost was higher in sedimentary soil (Jin-Ju) than in granite soil (San-chung), and the effect of lime was higher in the latter than in the former.
2. In the yield of soybeans, Jinju soil was generally higher than San-chung soil.
