The purpose of the study is to investigate factors influencing the adoption of environment-friendly agriculture in greenhouse vegetable production of Jeonnam province. An interview survey were conducted during 2008, including six counties: Gwansanku of Gwangju, Gwangyang, Goheung, Damyang, Boseong, and Suncheon. Major crops grown in surveyed area were green peppers, cucumbers, strawberries, cherry tomatoes, tomatoes, and watermelons. Logit model results show that adopters of environment-friendly agriculture are more likely to participate in extensional education programs, attend educational programs on environment-friendly agriculture, have greater cultivated acreage, and have larger agriculture-only-designated farmland. However the adopters are less likely to have greater number of family members participating in farming, and live Goheung county. Efforts should be made in extensional education programs to lead more vegetable growers to adopt environment-friendly agriculture. Policy makers’ additional efforts should be followed to increase adoption rate of environment-friendly agriculture in lower adopted areas.

The green craze has hit all the world lately. The green revolution which means immense changes for sustainable development under the new environment-economy system is foretelling that we should have new angle to the environment and economy. This paper is about the development of the model and indicators for construction of ECO(Energy Circulating Organic)-Village which is the green growth option of local community. This model is composed of three concepts - SPDC (about procedural methodology of Model), Virtuous Circle (about functional relationships of three requisites), Network (about spatial relationships between communities) - and evaluation indicators. Environment, tourism, industry (Energy & Organic Agriculture) are set as the three requisites for green growth of local community. Nations of the world plunge into the green war which is silent, general, sweeping changes. We can not win this war with the existing thinking system and policy. We need revolutionary changes reconsidering of environmental value and sustainable development strategy of the region. Each of us should go through the changes and this work would be the one among those efforts.

This study was conducted to research the status, history and prospects of farm scale milk processing and to develop a management strategy for small scale milk process plant in Korea. Also it aims to provide ways to apply it so as to vitalize the farm made milk products market practically. This study was also treats the practical development of dairy farm school programs through the farm scale milk processing. Farm-scale milk plant (FMP) should be some of the ideas to develop small scale and using the resources according to the local features, limited expanding in regional market , produce by consumers order amounts, management policy will be transferred organic dairy farm. A few policy suggestions to put FMP system of financial support would not from beginner, it is better to settled FMP system by government or co-operation group in practical support programs were proposed. What the state needs to do through direct involvement were to put efforts at demand expansion on FMP system products, to certificate and safety the farm made milk products marketing system settings, to build more variation chance of the milk products. What was more important, however, was support policy, to create the network of FMP market and to develop of training program contents for each FMP operation unit. The ideal FMP model for the development of Dairy Farming proposed in this research will be applied as a relevant reference in managing and realizing environmental friendly and sustainable dairy industry at the national level.

Japan launched its regulatory certification system for organic foods based on the amended JAS laws in June 2000, followed by the implementation of regulations on organic agricultural products and organic processed foods in January 2001 and with the implementation of the standards on organic animal husbandry and organic feed by the Ministry of Agriculture, Forestry & Fisheries in 2005, organic foods have been under integrated and systematic supervision. Certification of organic foods can be undertaken by registered accredited bodies (private certification bodies) or legal entities conforming to the regulations of the Ministry of Agriculture, Forestry & Fisheries. However, with the amendment of the JAS laws in March 2006, only legal entities conforming to the regulations of the ISO/IEC GUIDE 65 are eligible as certification bodies. Foreign organic products imported to Japan must be certified organic under JAS regulations and must be manufactured or produced by foreign manufacturers certified by local or foreign registered accredited organizations and distributed with the Organic JAS Mark affixed or through importers certified by local registered accredited organizations and distributed with the Organic JAS Mark affixed on the products. It can be implied from the Japanese case study that it necessary to reform the diverse agricultural products certification systems to set up an integrated certification system, and the restructuring of government organizations, reforms of environmentally-friendly agricultural products certification system and the integration of the organic food certification systems are needed in order to integrate the control of the standards and certification systems.

To investigate a comparison of rice yield and quality between organic and conventional cultivation, study for occurrence of rice diseases carried out in rice (Oryza sativa L.) field of Noahn and Bannam region. The results obtained as following: 1) Bactericide and insecticide were applied twice and four times at Noahn and Bannam region in conventional cultivation (C.C) of rice field, respectively, it was applied twice at two region in organic cultivation (O.C). Rice strip virus, leaf blast, neck blast, sheath blight, bacterial leaf blight, rice water weevil, rice leaf folder, and plant hoppers were occurred mainly in rice field. Leaf blast, neck blast, and rice leaf folder were occurred highly at O.C compared with C.C. 2) Growth level of rice in clum and panicle length was lower at O.C than C.C. Number of panicles per hill was by 0.6 higher at O.C than C.C. Number of panicles per hill was by 0.6 higher at O.C than C.C in Noahn region. Number of spikelets per panicle, grain filling ratio, brown/rough rice ratio, and weight of 1,000 grains was lower at O.C than C.C. Number of panicles per hill was by 0.8 lower at O.C than C.C in Bannam region. Number of spikelets per panicle and grain filling ratio was higher at O.C than C.C while brown/rough rice ratio was lower at O.C. Total yield percentage of rice in O.C was level of 84% at Noahn region and 94% at Bannam region compared with C.C. 3) Head rice percentage was lower at in O.C than C.C at two region. Protein and palatability (Toyo value) were lower at O.C than C.C in Bannam region causing occurrence of neck blast and rice leaf folder by oversupply of nitrogen fertilizer. Protein, whiteness, and palatability (Toyo value) were adequate level at O.C in Noahn region by lower nitrogen fertilizer.

This study was carried out to evaluate the effects of applying levels of organic liquid fertilizer (OLF) on growth and fruit quality of hot pepper. The OLF was made with compositions of chicken dung : rice bran : soybean meal (2:1:1). Hot pepper was applied with 5 treatments; control (chemical fertilize), OLF-1.0X (standard applying levels), OLF-0.7X (70% of standard applying level), and OLF-1.3X (130% of standard applying level). The plant height was reduced at 23cm in the OLF-1.0X treatment compared to control of 293㎝. The number of hot pepper fruits was significantly increased. The content of capsaicin in the ripened pepper decreased by 23.6% in the OLF-1.0X treatment with 253㎎ㆍ㎏⁻¹ compared with control of 331 ㎎ㆍ㎏⁻¹, but the content of free sugar increased by 19.5%. The content of capsaicin and soluble solid content in OLF-1.3X treatment were significant different with other treatments. The yield of red pepper in OLF-1.0X treatments increased by 15% with 4,190㎏ㆍ10a⁻¹ compared to control of 3,643㎏ㆍ10a⁻¹, and OLF-1.3X and OLF-0.7X treatments showed increase by 10% and 6%, respectively.

During 2005~2009, current status on the occurrence and the management of the major disease, insect and mite pests were investigated in the non-chemical or organic cultured apple orchards in Korea. Numbers of certified organic or non-chemical apple orchards increased from 14 in 2005 to 78 in 2008. Severe damages on leaves and fruits were caused by the several diseases such as marssonina blotch, bitter rot, white rot, sooty blotch and flyspeck, and the several insect pests such as apple leaf-curling aphid, woolly apple aphid, oriental fruit moth and peach fruit moth on the almost certified organic or non-chemical pest control orchards. About 10 and 18 environmental-friendly materials were used to control diseases and insect or mite pests, respectively. But, lime sulfur and bordeaux mixture to diseases and machine oil, plant oil mixed with egg yolk, and pheromone mating disruptions to insect pests were effective under the adequate conditions.

This experiment was conducted to evaluate two different types of feed additive as an alternative for antibiotics on growth performance and feed cost in growing and finishing pigs. One additive is an herb extract, with Fenugreek (Trigonella foenum graecum) as the main component, while the other feed additive contains aminolevulinic acid (ALA). In the first experiment, 128 grower pigs were allotted to 4 different treatment groups and replicated 4 times with 8 pigs per replicate; the trial lasted for 28 days. The positive control group (PC) which is the control group supplemented with antibiotics was significantly higher (p＜0.05) in growth rate (580.6 g/d) followed by the ALA group (532.0 g/d), there was no significant differences in terms of feed intake and feed efficiency. There were marginal reductions in feed costs measured as feed cost per head in ALA and HE added diet. However, the feed cost per weight gain of ALA treatment was higher than the control group (PC) supplemented with antibiotics. In the second experiment, 80 finisher pigs were allotted to 4 treatment groups and replicated 4 times with 5 pigs per replicate; the trial lasted for 70 days. The treatment group supplemented with an herb extract (HE) had a significantly higher (p＜0.05) feed intake (2,415.8 g/d) compared to the other treatment groups, but there was no significant differences in terms of growth rate and feed efficiency. Feed cost per head in HE and ALA treatments were higher than PC treatment, and feed cost per weight gain of HE was higher than PC treat (p＜0.05). The results from these experiments suggests that these two types of feed additives can both be used as an alternative for antibiotics without having a negative effect on the performance of the animals. And aminolevulinic acid was good in performance and production cost of grower and finisher pigs.

The study was conducted to investigate the effects of organic fertilizers and mulches on the growth and CO₂ assimilation in MM.106 apple trees. Growth and CO₂ assimilation of MM.106 apple trees grown in a greenhouse were affected by the nutrient concentrations and carbon (C) and nitrogen (N) ratio in the raw materials of organic fertilizers and mulches. The optimum C:N ratios, which makes microorganism convert the organic N into the inorganic N, were obtained in the organic fertilizer, poultry litter, green compost, and grass clippings, resulting in increasing single shoot height, SPAD, and CO₂ assimilation. The SPAD and CO₂ assimilation were affected by the treatments 5 weeks after the treatments, and then the tree growth was affected by the treatments 6 weeks later. The most efficient tree growth and development were observed in the 10 to 15 ㎎ㆍ㎏⁻¹ of the inorganic N in a soil, and the N was strongly related to the tree growth and development.

To investigate the possibility of discrimination between organic and non-organic rice using stable isotope nitrogen of natural abundance, organic rice of 17 samples and non-organic rice of 13 samples grown at adjoining organic rice field were collected in 2008. Rice was grinded into brown rice, milled rice and hull, and samples were analysed for nitrogen and δ¹⁵N at NICEM. Authors also made inquiries about N source for both farmers who conduct organic- and non-organic rice cultivation. In order to know whether the δ¹⁵N can be used in discrimination between organic and non-organic rice, discriminant analysis were made with SPSS and logistic method.
1. Organic farmers used manure, rice bran, used mushroom culture, fermented fertilizer (company products), and oil cake, but non-organic farmers applied compound fertilizer. Rice straws were remained in organic rice field while moved out in non-organic field.
2. There were difference in δ¹⁵N among organic rice and its byproduct(7.760‰ in hull, 6.720‰ in rice), but significant difference was not found between them. And the trend was same between province. Non-organic rice showed similar results.
3. Significant difference of δ¹⁵N were found between organic rice and non-organic rice (p＜0.01) and between hull of organic rice and that of non-organic rice hull (p＜0.05). δ¹⁵N seemed to be useful criteria for discrimination of organic and non-organic rice.
4. When applied discrimination analysis of SPSS and logistic, there were significant difference between organic rice, non-organic rice and its byproducts except brown rice and hull in SPSS method. Hull can be used as the most useful component for unknown sample prediction with 83.3% probability.

This study was conducted to investigate the effects of concentrated pig slurry and byproduct liquid fertilizer on the growth and yield of chinese cabbage. The experiment was conducted in a rain-shelter house which was installed in the agriculture farm. Plants were fertilized with concentrated slurry (CS), byproduct fertilizer (BF), mixture of concentrated slurry and byproduct liquid fertilizer (CS+BF), combined organic and chemical fertilizer (CS+BF+BF) and chemical fertilizer (CF) as control.
1. The pH level of byproduct liquid was decreased from the 3rd to the 7th day and increased 9 day to 14th day, but pH of concentrated slurry (CS) was not greatly varied. EC of concentrated slurry (CS) and byproduct liquid was increased gradually during the fermentation.
2. The concentrated slurry (CS) was low in phosphorus, calcium, magnesium, rich in potassium and unbalanced as a low nitrogen and high potassium. But byproduct liquid fertilizer was balanced in nitrogen and potassium ratio.
3. The leaf number, head height, head width of chinese cabbage in treatment with organic and chemical fertilizer (CS+BF+N) showed significant difference compared with control. The plant and head weight of chinese cabbage in treatment of concentrated slurry was severely decreased, but that in treatment organic and chemical fertilizer (CS+BF+N) were increased 8, 10% compared with control chemical fertilizer (CF), respectively.
4. The content of K₂O in plant tissue and in soil was increased after using concentrated slurry. On the other hand, mineral content of except K₂O did not differ significantly between any of the treatments. In conclusion, organic and chemical fertilizer (CS+BF+N) could improve growth and head weight of chinese cabbage.
