Ⅲ. 腐熟糞尿의 施肥가 배추의 生育과 收量에 미치는 影響 = Effects of the Application of Decayed human excrements on the Growth and Yields of Chinese Cabbage

다국어 초록 (Multilingual Abstract)

The human excrements sampled in Kwangju city were kept in the tank of storage for two months or more, in order to decay excrements and kill the parasite in the excrements completely. The decayed excrements obtained from the above treatment, and the fresh excrements were dressed on the Chinese cabdage. The results that we surveyed the effect of the excrements on the growth and yields of the Chinese cabbage were summarized as follows;
1. The diameter of bulbs were 16.2cm Control, 19.lcm in the fresh excrements and 20.6cm in the decayed excremets plot. The decayed excrements plot was greater than the other treatments(L. S. D. =2.50, 5% level).
2. The length of bulbs were 23.5cm in Control, 29.5cm in the fresh excrements plot and 29.3cm in the decayed excrements plot. Among these treatments, the decayed treatment plot was the highest in length(L. S. D. =4.09, 5% level).
3. The number of leaves were 73.8 in Control, 88.lcm in the fresh excrements plot and 95.3 in the decayed excrements plot, but there was no significance among treatments (L. S. D.=17.35, 5% level).
4. The weight of bulbs were 2,450.5g in Control, 2,736.7g in the fresh excrements plot and 2,876.3g in the decayed excrements plot. The decayed excrements plot was heavier than the other treatments(L. S. D. =22.05, 1% level).
5. The total weight were 58,937kgs in Control, 65.682kgs in the fresh excrements plot and 93,030kgs in the decayed excrements plot. From the above results, the decayed excrements plot showed the highest yields(L. S. D.=22,05, 5% level).
