Expectations were that fresh organic matter could be decayed to some extent during a period of crop growth when it was used as a growing medium, and theFuyodocould be obtained after the harvest of a crop. In the present experiment, grown was santosai (Brassica rapa L. var. amplexicaulis) a kind of chinese cabbage, and used organic materials were bagasse from a sugar factory and shavings and sawdust from a lumber factory. And investigated were such factors affecting the growth of the vegetable as the amounts of basal dressing, of calcium carbonate, of top dressing, the number of times of dressing and the ratios of mixing the respective organic materials. These treatment factors were arranged according to the orthogonal array L_<27>(3^<13>). The santosai was sowed on the pots (10.5cm diameter×15cm height) stuffed with the organic mixture and grown for 35 days in the glasshouse. The santosai showed the lowest yields as treated with neither basal dressing nor top dressing on the 1 : 1 : 1 mixture of bagasse, shavings and sawdust. The highest yields were obtained as treated with no basal dressing but with everyday-top dressing on the mixture of 9 : 1 : 9. The analysis of varience showed that only the factor of the top dressing had an effect on the yields of santosai at 5% of significance among the other factors., 紀要論文}, pages = {167--175}, title = {バガスとオガクズを利用した腐葉土の試作 : 第 2 報 試作過程における山東菜の生育に影響を及ぼす要因解析(農芸化学科)}, year = {1983} }
