This study was carried out to survey the distribution of farm-yard manure by analysis 355 samples collected from major flue-cured and burley tobacco area. The applied manure amount for flue-cured and burley tobacco were 1,500 kg and 1,600 - 2,000 kg per l0a, respectively. The major raw materials of farm-yard manure were cattle dung, chaff, and rice straw. The main manure used for tobacco plant were cattle dung+chaff, cattle dung+rice straw+chaff, cattle dung+rice straw, and poultry dung+chaff, which were mostly unfinished fermentation materials. The chemical characteristics of farm-yard manure were as follows: pH for 87% of samples was higher than 7.1, total nitrogen for 70% of samples was 0.51-1.50%, P$_2$O$_{5}$ for 48% of samples was higher than 1 %, $K_2$O and CaO were 1-2%, MgO was 0.5-1.0%, and Cl was lower than 0.5% level. In general, the manure used for tobacco cultivation was higher contents of chemical components than that of manure made by rice straw. Also, the concentration of chemical compounds in the samples collected from burley tobacco area were higher than that of flue-cured tobacco districts.s.

Calocybe indica, a tropical edible mushroom, is popular because it has good nutritive value and it can be cultivated commercially. The current investigation was undertaken to determine a suitable substrate and the appropriate thickness of casing materials for the cultivation of C. indica. Optimum mycelial growth was observed in coconut coir substrate. Primordia initiation with the different substrates and casing materials was observed between the 13th and 19th day. The maximum length of stalk was recorded from sugarcane leaf, while diameter of stalk and pileus, and thickness of pileus were found in rice straw substrate. The highest biological and economic yield, and biological efficiency were also obtained in the rice straw substrate. Cow dung and loamy soil, farm-yard manure, loamy soil and sand, and spent oyster mushroom substrates were used as casing materials to evaluate the yield and yield-contributing characteristics of C. indica. The results indicate that the number of effective fruiting bodies, the biological and economic yield, and the biological efficiency were statistically similar all of the casing materials used. The maximum biological efficiency was found in the cow dung and loamy soil casing material. The cow dung and loamy soil (3 cm thick) was the best casing material and the rice straw was the best substrate for the commercial cultivation of C. indica.

겨울철 동안 속성퇴비(速成堆肥) 제조(製造)를 위한 P. E. Film House(비닐하우스)를 이용(利用)한 볏짚 부숙(腐熟) 시험(試驗) 결과(結果)는 다음과 같다. 1. 12월(月) 8일(日)부터 3월(月) 8일(日)까지 동계기간(冬季期間)동안의 온도변화(溫度變化)를 보면 비닐하우스 내부(內部)의 최고온도(最高溫度)는 $20^{\circ}C$ 정도(程度)로 $0^{\circ}C$ 내외(內外)인 야외(野外)의 최고온도(最高溫度)에 비(比)해 상당히 높게 유지(維持)되었고 일조(日照)가 양호(良好)할수록 그 차(差)는 더욱 컷다. 또한 비닐하우스 내부(內部)의 최저온도(最低溫度)는 대부분(大部分) 빙점(氷點) 이하(以下)였으나 야외(野外)보다는 $1{\sim}5^{\circ}C$ 정도(程度) 높았으며 일몰후(日沒後)에는 주간(晝間)의 잠열(潛熱)이 그리 많이 축적(蓄積)되지 못했다. 2. 비닐하우스 내(內)에서 볏짚 퇴적물(堆積物)의 전면(全面)비닐피복(被覆)과 상면(上面)비닐피복(被覆) 측면(側面)이엉피복(被覆) 두 처리(處理) 모두 내부(內部)의 최고(最高) 부숙온도(腐熟溫度)가 $70^{\circ}C$를 상회(上回)하나, 전면(全面)비닐피복처리(被覆處理)가 더 높았고 지속기간(持續期間)도 길었으며, 뒤집기를 한 후(後)의 온도(溫度) 재상승(再上昇) 속도(速度)가 빨랐고 최고온도(最高溫度)도 높아 미생물(微生物)의 번식활동(繁殖活動)이 빨리 왕성(旺盛)하게 되어 부숙(腐熟)이 촉진(促進)되는 것 같다. 3. 야외(野外)에서의 두 처리간(處理間) 차이(差異)가 현저(顯著)하여 상면(上面)비닐피복(被覆) 측면(側面)이엉피복(被覆) 처리(處理)는 뒤집기로 인한 열방산(熱放散)으로 퇴적물(堆積物)의 내부온도(內部溫度)가 빙점(氷點)에 머물면서 재상승(再上昇)까지의 기간(期間)이 매우 길어 1월(月)의 경우에는 40일(日)이 소요(所要)된 반면, 전면(全面)비닐피복(被覆)은 뒤집기를 한 직후부터 온도(溫度)가 재상승(再上昇)되었다. 4. 비닐하우스 내(內)에서 부숙처리(腐熟處理)는 3회(回) 뒤집기가 가능(可能)하여 완숙(完熟)에 가까운 부숙(腐熟)을 보였고 특히 전면(全面)비닐피복처리(被覆處理)는 부숙도(腐熟度)가 33%로 거의 완숙퇴비상태(完熟堆肥狀態)를 보였다. 한편 야외(野外)에서는 2회(回)의 뒤집기가 있었지만 부숙촉진효과(腐熟促進效果)는 미미(微微)하였고, 상면(上面)비닐피복(被覆) 측면(側面)이엉피복처리(被覆處理)는 부숙(腐熟)이 지연(遲延)되었다.
