The production of bio-energy crops is a major research project in the emphasizing the “low carbon ․ green growth” strategy. For this, the possibility of the introduction of the new energy crops improve the agricultural income from farming must be diagnosed. This study describes the level of agricultural income per unit area by cropping system based on the income of crops in the field. Especially, we have chosen the southern part attracting the attention in the possible area of the bio-energy crop production. This study consists of five chapters. Chapter Ⅰ is the introduction. Chapter Ⅱ is on the status of the southern part cropping system and the analysis of the economic value. Chapter Ⅲ is on the economic value analysis introducing new bio-energy crops. Chapter Ⅳ is on the comparative analysis for the economic value of the croping system introducing new bio-energy crops. Chapter Ⅴ is the conclusion.

This paper evaluates the technical efficiency of organic farm management practices and studies its main determinants in Hongdongmyeon of Hongsung county, Chungnam province. The analysis is performed in two stages. First, the efficiency is measured via the nonparametric “Data Envelopment Analysis” (DEA) technique. The DEA models are constructed not only to assess the overall technical efficiency of organic farming practices but also to evaluate the management efficiencies. In a second stage critical determinants of efficiency are determined using a Tobit model. In this analysis the focus is on technical and socio-economic variables. The analytical results show that technically efficient farms is about 13 percent and the mean technical efficiency is found to be 0.73 indicating that many farms are not operating at an efficient scale.

The theme-type self-harvest concept proposed in this research will be applied as a relevant reference in planning and realizing urban-rural exchange facilities at the village level. The aim of this paper is to describe the concept, to characterize the self-harvesters and organic farmers involved, to illustrate the ecological, economic and social interaction and the possible constraints of the concept. What is more important, however, is to develop programs for consultants, organic farmers and green-minded consumers, to vitalize direct transaction. The proponents of selfharvest are convinced that this concept leads to ecological, economic and social benefits, which will help to design a sustainable food supply system for small, medium and large cities.

In this paper, we assessed the growth of rice seedlings(Chucheong variety) in commercial organic growth medium that was substituted with different ratios of vermicast of oyster mushroom waste grown under potting alone, and potting and floor layering treatment. The commercial organic growth medium was substituted with vermicast at ratios of control, 2%, 4% and 6%, respectively. The contol consisted of commercial organic growth medium alone without vermicast. Incorporation of 4%~6% vermicast of oyster mushroom waste into a commercial organic growth medium enhanced the growth of rice seedlings significantly as compared to commercial organic growth medium alone(control), and 2% amended with vermicast in potting treatment. This results demonstrate that substitution with low ratios of vermicast(4~6%) will promote growth of rice seedlings. The growth of rice seedlings in commercial organic growth medium alone without vermicast was enhanced significantly as compared to the substituted with vermicast in floor layering treatment, it may due to nutrient uptake by elongated root from the vermicast when applied to on the floor layering. Floor layering treatment is an effective method for potting processing of vermicast. The vermicast of oyster mushroom waste should have a high safety and great potential as materials of growth media for increasing plant growth, either as soil conditioner, or as substitution or amendments to commercial organic growth medium. For the enhanced growth of rice seedlings, demand to increase with total nitrogen, and decrease with the carbon and nitrogen ratio(C/N) of commercial organic growth medium supplied by such as vermicast.

This review was conducted to the study on treatment of poultry waste by earthworms, and the effect of feeding earthworms meal on the performance of broilers and laying hens, and safety of meat and egg.
1. The pro-environmental chicken house was building in Daegu National University of Education, Daegu city, chicken wastes will be turn into high quality compost by vermicomposting uses earthworms in the house.
2. The earthworm meal (EWM) has a high proteinic content and a balanced amino acid and fatty acid profile, therefore most feeding applications has been evaluated with mono-gastric animals.
3. The dietary supplementations of 0.2 to 0.4% EWM were effective in improve digestibility of crude protein of diet resulted improved broiler performance in broiler chickens.
4. The supplementing 0.2 to 0.6% of earthworm meal in the laying hens diet, improves the laying performance and egg quality, especially ratio of egg yolk n-6/n-3 fatty acids contents.
5. As, Cd, Cr, Hg and Pb were detected at level of 4.41, 1.23, 1.18, 0.00 and 3.39ppm in earthworm meal, respectively, but those were not detected in the chicken meat and egg. therefore supplementing 0.6% of EWM in the chicken diet, it still did not affect meat and egg safety.
6. These results indicated that vermicompositing uses earthworms good a subject matter in the pro-environmental animal husbandry.

This study was carried out to investigate the effect of application of spent mushroom compost(SMC) on soil chemical properties and tomato growth. After the mushroom has been harvested, the SMC contains a lot of organic material, different microorganism and high density of mushroom hypha. SMC of white button mushroom(Agaricus bisporus) contained diverse microorganisms including fluorescent Pseudomonas sp. and actinomycetes. These isolates showed strong antagonistic to bacterial wilt(Ralstonia solanacearum) and fusarium wilt(Fusarium oxysporum) of tomato. The growth and sugar content of tomato showed no significant difference with other treatments by stage of maturity. The EC, exchangeable K and Ca contents of the soil during growing stage were increased in comparison to those of farmhouse practice, but available phosphate decreased. Microbial population in the soil in all growing stages showed no significant difference with other treatments, but yield of tomato decreased in some way in comparison to farmhouse practice. As the result of analysis on chemical property of soil and plant growth and yield of tomato, it seems likely that SMC of white button mushroom(Agaricus bisporus) may be used as substitute of practice compost on cultivation of tomato.

This study was carried out to determine the effect of application seasons and rates with animal liquid slurry on the rice yield and quality. The treatments were application seasons (autumn, spring) and application rates of animal liquid slurry 80, 100, 120, 140% N levels of based on 11㎏ N/10a, chemical fertilizer as control plot. Field experiment was conducted at Cheorwon, Gangwon-Do in 2007. The results was as follows; The plant height and tiller’s number at the application of spring season were higher than that at the autumn application. In the plot of 140% level at the spring application, the plant height and tillers were higher, and the color of leaf was darker than that of the chemical fertilizer. The plot of 140% level in spring application was increased the lodging damage of rice. Rice yield was reduced at 7%, 13% in the plot of 120%, 140 N/10a slurry level in the spring application compared to the chemical fertilizer, respectively. But rice yield at the autumn application was not significantly difference between chemical fertilizer and plots of liquid manure. The rice quality of the 120 and 140% slurry in spring application was significantly lower than that of chemical fertilizer. Total nitrogen contents and nitrogen uptake in rice plant were higher at the plot of 120, 140%N in the spring than that of chemical fertilizer. To reduce the lodging damage and increase the yield and quality of rice was needed suitable application of liquid manure in spring season.

Pitamin is a component of pine bark extract that exhibits antimicrobial activity and a variety of physiological effects. This study was carried out to investigate the effects of dietary pitamin as an organic livestock feed additive in broiler chickens. A 35 day trial was conducted to determine the influence of dietary premix containing 5% pitamin; investigated parameters included blood lipids, growth performance, quality characteristics of carcasses, and changes of caecal microbials in broiler chickens. Chickens were randomly divided into groups that were untreated (control), treated conventionally with antibiotics in the absence of premix, received 0.1% or 0.2% premix containing 5% pitamin. Plasma lipids were lower in groups fed diets with pitamin premix (p＜0.05). The body weight gain from broiler chickens fed with the diet containing 0.1% pitamin premix and antibiotics was similar, and was significantly higher than that of the other groups (p＜0.05). The weight of breast muscle and thigh meat of carcasses was similar, and was higher than that of the control group (p＜0.05). Abdominal fat and thymus index from chickens receiving either pitamin-supplemented premix was significantly lower and increased, respectively, that of the antibiotic and control groups (both p＜0.05). The chickens on the pitamin premix-supplemented diets evidenced significantly higher caecal levels of Bifidobacterium species as compared with the chickens on the control diet (p＜0.05). These results suggest that feeding a diet supplemented with a 0.1% premix containing 5.0% pitamin for 35 days maintains the production of broiler chickens at a level comparable to that obtained from the use of antibiotics.
