To know the effect of water treatment sludge (WTS) as a rice seedling culture soil, rice seeds are sown, germinated and grown on the culture soils mixed with different ratios of WTS to sand (100:0, 50:50, 30:70, respectively), and their growth effects was compared to that of control, commercial culture soil. When WTS is used as a culture soil for rice, the length and weight of the top part of rice seedling somewhat decreased than those of control treatment while their root length and weight in all WTS treatments significantly increased. Although phosphorus and potassium uptake of rice seedling in WTS treatments was slightly decreased, WTS treatment showed to develop root growth which is necessary in the seedling stage of all plane. Such a stimulatory effect on root growth of rice seedling was significant in the mixture ratio of 50% WTS to 50% sand.

The present study was performed to identify the possibility of the disused paper-sludge to substitute an substrate for nursery plants. Tosilee substrate as control, paper-sludge and tosilee substrate (1:1, v:v), and paper sludge substate were used in this experiment. After harvesting tomato seedlings, there were no significant differences in growth parameters such as plant height, root length, and fresh and dry weight grown for tosilee substrate, and paper-sludge and tosilee mixture substrate. However, the seedlings grown for paper-sludge substrate alone were extremely depressed. These growth pattern was followed by cucumber seedlings. As the result of this experiment, we suggest that it must need to stabilize the pH and EC, and Zn concentration in paper-sludge for increasing its material for substrate.

This study was conducted to develop the homemade soil media adequate to raising rice seedlings for machine transplanting. A raising experiment of rice seedlings was tested on a newly developed soil medium made mainly from briquette ash compared to ones of infertile red earth and fertile paddy loams. Dry weight of rice seedlings at 36 days after seeding was slighly lower in the plot of briquette ash that in soils, however, it was quite good in the plot of briquette ash mixed with zeolite and diatomaceous earth. pH in soil media was high in briquette ash and also high in soils mixed compost compared with out compost treatment, resulting in higher occurrence of damping off or physiological disorder. Good rice seedlings could be raised in soil media without compost and briquette ash mixed with zeolite diatomaceous earth.

The experiment has investigated the effects of blending rate of waste rockwool in nursery media on growth of Marygold 'Yellow boy' plug seedlings. A commercial plug medium containing 10% zeolite, 10% vermiculite, 5% perlite, 10% peatmoss and 65% cocopeat was used as the control, and the other media compounded with 10% of zeolite, vermiculite, perlite and peatmoss and 10, 30, and 50% of waste rock-wool. There was not significant difference in germination rate ot Marygold between treatments. Plant height, number of leaves, stem diameter and leaf area were higher in commercial plug medium and compound nursery media containing 50% of waste rockwool than 30 or 10% of waste rockwool. Fresh weight and dry weight of shoot and root increased in the treatment of commercial plug medium and the medium of 50% waste rockwool than 10 and 30% of waste rockwool. These results suggested the possibility of utilization of waste rockwool for medium components of plug seedlings.

최근 유기농산물의 생산 및 소비 증가에 따라 건전묘 생산을 위한 유기상토의 개발이 요구되고 있다. 우리나라에서의 유기상토는 현재 수도용과 원예용 및 기타용으로 크게 3가지로 구분되고 있으며, 원예용은 채소용과 화훼용으로만 구분되고 있다. 이에 본 연구에서는 작물 특성에 따라 과채류와 엽채류로 구분하여 양질의 묘를 생산하기 위한 유기상토를 개발하고자 수행하였다. 개발 유기상토의 원자재는 초탄, 피트모스, 질석, 펄라이트, 제올라이트, 맥반석 및 고형비료의 배합비율을 달리하여 제작하였고, 공정육묘판을 이용하여 작물별로 개발상토와 대조상토로 구분하여 3반복으로 시험하였다. 배추의 경우 개발상토에서 모든 묘소질이 대조상토 보다 좋았으며 광합성 효율을 나타내는 엽면적 지수는 개발상토가 $3.14cm^2$/개 으로 대조상토 $2.91cm^2$/개 보다 높은 결과를 보였다. 육묘트레이당 20개씩 골라 측정한 생체중 및 건물중은 개발상토에서 2.41g과 0.30g으로 대조상토에 비하여 각각 122%, 231%가 증가된 것으로 조사되었다. 오이의 경우, 상토간 엽수의 차이는 보이지 않았으나, 다른 모소질에서는 개발상토가 좋은 결과를 보였다. 고추의 경우 개발상토에서의 엽수는 평균 9.5개인 반면 대조상토에서는 8.5개였다. 초장에서도 개발상토에서 평균 4.2cm정도 컸으며, 엽면적지수 또한 $2.02cm^2$/개로 대조상토의 $1.74cm^2$/개보다 좋은 결과를 보였다. 개발상토를 이용한 고추묘 20개의 평균 생체중은 4.15g이었으며, 대조상토 에서는 2.94g으로 큰 차이를 보였다. 작물특성에 따라 원예용 유기상토를 엽채류용과 과채류용으로 구분하여 생육특성을 조사한 결과, 초장을 비롯한 모소질이 본 연구에서 개발한 상토에서 양호하게 나타나 유기원예육묘용 상토로 적당한 것으로 판단된다.

Clubroot disease of Chinese cabbage has extremely occurred in recent years. Conventional soils such as sandy loam soil (saprolite) and clay soil (yellow soil) as bed media combined with field soil application of fungicidal chemicals were tested for the control of clubroot disease. Using sandy loam soil and clay soil as plug seedling bed media efficiently reduced clubroot disease occurrence down to 21.7% and 14.1%, respectively compared to peatmoss (75.7%) and Baroco soil (36.6%) when seedling plants were transplanted into previously-infected Yoncheon field. Application of flusulfamide and azoxystrobin to previsouly-infected soil prior to transplanting also effectively reduced disease incidence, especially when combined with growing seedlings in sandy loam or clay soil media. In conclusion, flusulfamide application prior to trnasplanting as well as utiliz-ing sandy loam and clay soil as a plug bedding media may effectively reduce the occurrence of clubroot dis-ease of Chinese cabbage.

This study was conducted to investigate the optimal conditions for spore germination, prothallus propagation, sporophyte formation and seedling growth in Microlepia strigosa (Thunb.) C. Presl. Spore germination and prothallus development were promoted by low concentrations of Knop medium nutrient solution. The optimal medium for prothallus propagation and antheridium formation was 2X MS medium with 3% sucrose. The activated charcoal content of the medium did not affect prothallus proliferation. Among the various combinations of culture soil (bedding soil, peat moss, perlite and decomposed granite), a mixture of bedding soil, peat moss and decomposed granite at a ratio of 1 : 1 : 1 (v : v : v) had a positive effect on sporophyte formation. The most efficient conditions for promoting the growth of whole plants (sporophyte seedlings) were 50 - cell plug trays filled with a mixture of bedding soil and decomposed granite at a 2 : 1 (v : v) ratio.

The aim of this study was to evaluate the effect of 3 environment- friendly farming materials on the growth of pepper and tomato seedlings under low level of solar radiation. The pepper and tomato seedlings were separately grown on commercial substrate and non-fertilizer substrate under 30% shading condition, respectively. The microbe-, enzyme-, and amino acid-supplements were used for the foliar application to the seedlings. The application of enzyme- and amino acid-supplements significantly enhanced the growth of tomato and pepper seedlings grown on non-fertilizer substrate, while there was no significant effect on the seedlings grown on commercial substrate. The foliar application of enzyme- and amino acid-supplements reduced the days to flowering by 3 to 4 days and lowered the node order of fruit set in tomato plants grown on non-fertilizer substrate. The results showed that the enzyme- and amino acid-supplements could enhance the seedling growth and lower the node order of fruit set under limited nutritional conditions.
