This study was conducted to evaluate the effects of fowl dzopping. saw dust and rice hall on the soil microflora in vitro. The experiment was designed in seven treatments with the various organic materials and they were only soil (control). soil + fowl dropping (S+F), soil+fowl dropping+rice hull (S+F+R) soil+fowl dropping*saw dust (S+F+S). soil+chemical fertilizer (S+C.F), fowl dropping+rice hull (F+R) and fowl dropping+saw dust (F+S). All the samples of treatment were incubated in $28{\pm}2^{\circ}C$ condition and tested the activity of soil microflora for 84 days The activity of fungi, total bacteria, gram-negative bacteria and actinomycetes showed the highest values at, twenty-first day and the spore-forming bacteria was at forty-second day after incubation. The number of fungi and gram-negative bacteria showed the highest values in the treatment of F+S, the spore-forming bacteria and the actinomycetes were in the S+F+S. and the number of total bacteria was in the F+C.F., but in the treatment of F+R. all the microorganism except fungi showed the lowest values in their numbers. The composition ratio of dead bacteria was higher in the treatments of S+F+R and F+R than in those of others as 70% and 40% respectively. Actinomycetes isolated from the treatments of S+F and S+F+S were identified as Streptomyces sp.. Nocardia sp., Micromonospora sp. Actinomadura sp. and Saccharomonospora sp.

The present study was carried out to evaluate the effects of organic liquid fertilizer (OLFs) fertigation on the growth and fruit quality of hot pepper (Capsicum annuum L.) cv. 'Nokkwang (Seminis Korea)'. Treatments were given with control (chemical feritilzer), OLF I(fowl dropping : fish meal : soybean meal, 2:1:1), OLF II(fowl dropping : bone meal : soybean meal, 2:1:1), OLF III(fowl dropping : bone meal, 1:1), and OLF IV(fowl dropping : rice bran : soybean meal, 2:1:1). The composition ratio of OLF based on weight to weight. The pH and EC of OLFs according to different material and compositions ranged from 6.5 to 6.8, and from 2.91 to $3.69dS{\cdot}m^{-1}$, respectively. The C/N ratio was the highest as 5.75 in OLF Ⅳ, and there was no difference among the treatments in C/N ratio of the exception of OLF IV. In OLF IV total fruit weight was the highest as 1,558g per plant and total fruit number increased as 23.7% compared to control. The content of capsaicin in the ripened pepper increased with OLF I and II treatments, and decreased with OLF III and IV treatments compared to control of $662mg{\cdot}kg^{-1}$, but the soluble solid content was the highest with OLF IV treatment as $10.0^{\circ}Brix$.

The result of application of the organic manure obtained from livestocks fed with BLCSs in the red pepper under structure were as follow. The no. of fruit. fruit weight. fruit length. fruit width. and sugar content of red pepper treated with dong of fowl(BLCS) were higher, also. The contents of total N, P2O5, K2O, CaO, MgO, and cap-saicin in the red pepper fruit of treated with Dung of fowl(BLCS) were the highest, and the second was cattle dropping(BLCS). The contents of OM, P2O5, K, Ca, Mg, and CEC of soil treated with microorganism were the highest in the cattle dropping(BLCS) in any other plots, however. In general, effect of cattle manure fed with BLCS on the red pepper yield and microbial activity were higher than cattle manure did not feed BLCS.

The result of application of the organic manure obtained from livestocks fed with BLCS in the altari radish under structure were as follow. The no. of leaves, leaf, root length, root width, and total weight of altari radish treated with dong of fowl(BLCS) were the highest in any other treatment, and cattle drop-ping (BLCS) was higher, also. The contents of total N, P2O5, K2O, CaO, MgO, and sugar content in the altari radish treated with dong of fowl(BLCS) were the highest, and the second was cattle dropping (BLCS). The contents of OM, P2O5, K, Ca, Mg, and CED of soil treated with microorganism were the highest in the cattle dropping (BLCS) in any other plots, however. In general, effect of cattle manure fed with BLCS on the altari radish yield and mi-crobial activity were higher than cattle manure did not feed BLCS.

This experiment was carried out to investigate the effect of fertilizers on yield and paeonol content of Paeonia moutan Sims according to cultivation years. Tested variety was a local cultivar and fertilizer treatments used were compost (3, 000kg/10a), N-P-K (10-10-10kg/10a) fertilizer, fowl dropping manure (100kg/10a), organic fertilizer (200kg/10a) and non-fertilizer. Root yield increased by 12% in N-P-K fertilizer, 18% in compost, 22% in fowl dropping manure and 26% in organic fertilizer treatment compared with non-fertilizer. Increment rate of root yield according to cultivation years from 3 to 6 year cultivation was highest in 5 year cultivation. Paeonol content was highest of 3.08% at October harvest and 3.63% in the fowl dropping manure treatment. Paeonol content was higher at longer cultivation year, but increment rate of paeonol content per year was low from 3 year cultivation. Partial paeonol content of root increased in the order of lower part (3.07%), middle part (2.77%), and upper part (2.38%).

This experiment was carried out to investigate the effects of various fertilizers on the growth and yield of tree peony Moutan cortex RADICIS from 1990 to 1994. The paeonol content, a main medical ingredient of tree peony, was 0.5% in the control, and the contents of the chemical fertilizer(N-P-K) and the two-kind compound fertilizer treatments were $0.26{\sim}0.41%$, and those were lower than $0.40{\sim}0.45$ of the compost, the fowl dropping manure and the organic fertilizer treatments. The weights off dry root(radix) rind were increased by 42% in the fowl dropping manure treatment and by 49% in the compost treatment compared with 151kg/10a in the control. All things considered, compost, fowl dropping manure and organic fertilizer were more effective than chemical fertilizers for the culture of tree peony.

This experiment was carried out to clarify the effect of different fertilizer on growth and yield of Fritjllaria thunbergii in Chungbuk Rural Development Administration from 1993 to 1995. Emergence date was faster about 1 to 5 days in fertilizer application than that of non-fertilizer, and emergence ratio was lower about 2.4% to 35.7% in fertilizer application than that of non-fertilizer. Plant height was longer about 2.8cm to 10.6cm in fertilizer application than that of non-fertilizer, and leaf length and width had same tendencies. Bulb height was increased about 0.1 to 0.2cm in fertilizer application than 1.9cm in non-fertilizer and bulb width was increased about 0.5 to 0.7cm in fertilizer application than 2.2cm in non-fertilizer. Total yield was increased about 27% in N-P-K fertilizer, 24% in compost, 23% in compound fertilizer for garlic and 21 % in fowl dropping manure than 572kg/10a in non-fertilizer. Yield of marketable goods was high about 79% in compost. 72% in compound fertilizer for garlic and fowl dropping manure, and 69% in organic fertilizer than 229kg/l0a in non-fertilizer. Therfore, in the cultivation of Fritillaria thunbergii the application of organic fertilizer such as compost and fowl dropping manure was considered more profitable than the application of chemical fertilizer in middle region.

Soil pH is an intensity factor of releasing hydrogen ion which is buffered by aluminum. It depends on pH buffer capacity of Al whether soil pH is governed directly by cations or not. A study was conducted to elucidate the pattern of pH changes by soil EC. Fertilizer and three kinds of organic manures composed of cow and pig and fowl dropping and one kind of rice straw compost were added independently into upland sandy loam soil. This treated soils and four upland soils under plastic film house having different levels in electrical conductivity (EC) were incubated with field capacity at $30^{\circ}C$ for 5, 10, 20 and 40 days. Soil pH varied directly as the cations contained in organic materials according to degree of saturating pH buffer capacity (pBC) of sandy loam soil. pH of the soils under plastic film house was lowered by soil EC due to governing by overplus of cation beyond pBC.
