This study was carried out to investigate the effect of soil microorganisms on yield of radish (Raphanus sativus L.). Six soil microorganisms, MPK+Husk+Palma, Husk+Palma, MPK+Compost, Compost, Bio livestock cattle system (BLCS) cattle dropping, and Tomi, were used. All of soil microorganisms were very effective to increase yields of radish. Especially, MPK+Husk+Palma treated plot was the most effective than any other plots. As a result of analysis of plant chemical components, compost treatment showed higher concentration of Mn than other soil microorganism treatments. In a chemical components of soil, concentrations of P and Mg were increased with Tomi treatment, and Na was increased with BLCS cattle dropping treatment. The other concentrations of plant and soil chemical components were not different, however. In a microbial properties of soil, Tomi, Husk+Palma, and MPK+Husk+Palma treated plots increased in the number of total bacteria and bacilli. Tomi treated plot increased in the number of actinomycetes and Fungi. The other microbial properties of soil were not different. It would be assumed that yield increase of radish might be due to the beneficial microbial properties, therefore, those would increase yields of radish.
土壤改良劑 處理가 양배추와 시금치의 收量에 미치는 影響

This study was conducted to find out the effect of several soil conditioners on growth of cabbage and spinach, and analized plants and soil chemical composition. The results are summarized as follows: 1. Among the growth characteristics of cabbage, soil conditioner treatments were increased leaf width, leaf length, head width, head height, head weight, and total fresh weight. 2. Among the growth characteristics of spinach, soil conditioner treatments were increased no, of leaf, leaf width, leaf length, and fresh weight. 3. In analysis of plant compositions, N, P_2O_5, K_2O, MgO, Na_2O content of soil conditioner treated plant were more increased than control, in general. 4. In analysis of soil compositions, K, Ca, Mg, P_2O_5, EC were more increased than control, in general.

There are many materials and agents in soft plastics film for Protected Cultivation. These are Polyethylene, Ethylene-vinylacetate, Polyvinylchloride ect. in materials and Stabilizer, Surfactant, Antihazier ect. in agents. This study was conducted to know characteristics of light transmission, minimum temperature in winter and tomato growth, yield. The results are summarized as follows ; 1. Changsu was shown the most stable change of contact angle which was influenced water droplet in inner film surface. 2. Light transmission was decreased in proportion of increasing contact angle after 10 months. 3. Effect of temperature maintenance in Samjung PE was 27% higher than PE. 4. Light transmission and efficienty of Samjung PE were 78.0% and 72.8%, it was 6.3% and 3.5% higher than PE(control), respectively. 5. Samjung PE was superior to any other materials in view of tomato growth and yield.
Vitabio 土壤微生物劑 處理가 葉상치 收量 및 品質에 미치는 영향
김경제,이병무 한국유기농업학회 2004 韓國有機農業學會誌 Vol.12 No.3
This study was carried out to investigate the effect of soil-born microorganism, vitabio on growth of leaf lettuce in the vinyl house. Total weights of leaf lettuce treated with vitabio showed difference compared with untreated leaf lettuce. Sugar content was also increased. Mineral contents of leaf lettuce showed no difference between treated with vitabio and untreated with vitabio. Exchange Capacity (EC) and Organic Matter (OM) in chemical properties of soil treated with vitabio showed higher than soil in untreated vitabio. Vitabio treated soil contained much more microorganisms such as Bacteria, Actinomycetes, Hyphomycetes, Bacillus sp. Pseudomonas sp. after harvest.
