Sunchon National University Farming Promotion Center is a unique social education institution for the farmers. This study intends to analyze the educational and training programs for future farmer candidates with a expert technology, successors to the rural leaders of Saemaul Movements, expert farmers, the students of farming practice courses in the Department of Agricultural Education, and the citizens participating in the social education courses. It is an urgent problem to recruit the experts in social education, and in specialized and advanced farm management technology. A committee for the betterment of the social education program should be consisted of the social education experts, and alumni of the Farming Promotion Center to share their farming information with one another. In order to achieve the successful goal in the education program of the Farming Promotion Center, the well planned field trips and the supervised farming practices should be secured, and the follow-up management system for the people finishing the courses of the educational programs should be formulated.

The purpose of this research is to go beyond the policy support of the traditional sixth industry and to build a business model of the farmers' business by establishing the business model of the establishment of the sixth industry utilizing agricultural products of individual farmers. First, we defined the business model of the 6th agricultural industry, and secondly set up two models via FGI based on the 9 block model of BMC (Business Model Canvas), and applied feasibility, cost appropriate, differentiation point Through the establishment of hard-working business, sales consolidation, consumer-centric model set. Third, using the Delphi method in each area of 9 Block, the final 21 components were set. Through this BMC model, it was shown that discrimination and accessibility are important factors in the 6th agricultural field foundation business model.

A survey was conducted to get information on the utilization of irrigation systems for greenhoyses farming. Three regions were selected which represent geographical chatacteristics such as neighboring urban area, flat-field area, and mountainous area. The number of greenhouses farms interviewed was 432 in total. The contents of the survey consisted of general characteristics of greenhouse farmers, the size and location of greenhouses, cultuvated crops, irrigation method, irrigation scheduling, and irrigation automation. The analysis of the surveyed data showed that greenhouse farmers did not take technical assistances. Proper criteria or guidelines for selection and operation of irrigation systems were not available. Irrigation systems were operated by hand. Irrigation scheduling were executed by farmer's experience. Maintenance of irrigation systems in general were poor. Development of economically reasonable irrigation system is of importance.

Pollutant loading potential was evaluated for manure application practices on farm fields, through survey and pot experiments. The survey indicated that most farmers applied the manure during the early spring. About 74% farmers apply the manure during the period from December to May. Considering the monthly rainfall amount in this period, the pollutant loading potential is not high. Leachate obtained from pot piled up with manure compost, using a rainfall simulator, showed that average concentrations of COD, SS, TKN, N $O_{3-}$N, TP were up to 2,000mg/L, 240mg/L, 107mg/L, 10mg/L, 50mg/L, respectively. These concentrations could be affected by rainfall intensity and the amount of piled manure compost. Therefore, implementation of management practices are recommended to control or minimize of leachate from manure compost piled on farm field.

본 연구의 목적은 강원도 고냉지 씨감자 경작자들의 잡초방제 및 제초제 사용에 따른 문제점을 파악하는데 있다. 강원도 평창군, 횡성군, 강릉시에 거주하는 씨감자 경작자 196명을 대상으로 설문조사를 실시한 후, 결과를 통계 분석하였다. 씨감자 경작자들은 경작지에 문제가 되는 주요 잡초로 여뀌, 명아주, 쑥, 닭의장풀, 바랭이, 봄여뀌, 별꽃, 쇠뜨기, 쇠비름을 들었다. 전체 응답자의 58%는 paraquat, pendimethalin, metribuzin 등 많은 제초제들을 단독 혹은 혼합하여 기준약량보다 2배처리하여도 여뀌, 쇠뜨기, 쑥, 둑새풀, 닭의장풀, 피는 방제가 힘들다고 답하였으며, 또 응답자의 34%는 현재 사용중인 제초제들을 $3{\sim}5$년 정도 연용하고 있다고 밝히고 있다. 조사대상자들은 paraquat, fluazifop-butyl 등 감자경작용으로 등록되지 않는 제초제들도 사용하고 있으며, 현재 사용되고 있는 제초제는 경작자 본인의 경험에 의한 선택(51%)과 농약상의 추천(34%)에 의하여 주로 선정되고 있는 것으로 밝혀졌다. 전체 응답자의 67%는 제초제의 남,오용으로 인하여 작물피해를 입은 경험이 있고, 75%는 제초제 처리시 혹은 후 제초제에 중독된 경험이 있다고 응답하였다. 강원도 고냉지 씨감자 경작자들은 제초제의 남,오용으로 경제적 피해는 물론 중독증상까지 경험하고 있으므로, 이 지역 경작자를 대상으로 한 올바른 제초제의 선정 및 사용법에 대한 체계적인 교육프로그램이 개발, 보급되어야할 것이다.

Sweetpotato fields in Korea are highly infected with virus and virus like diseases that greatly diminish both yield and quality as indicated by field observations and laboratory tests. In order to solve this problem, there is an urgent need to produce and mass propagate virus-free planting materials for distribution to the farmers. These experiments were conducted, firstly, to determine the most appropriate culture media, nutrient solution, and cutting intervals to maintain growth and vigor of tissue cultured plantleta as mother plants for propagation in insect-proof greenhouse. And as a labor saving method, the production efficiency of plug trays for rapid propagation of stem cuttings as a source of planting materials was likewise evaluated. Results showed that plants grown in medium B supplied with 0.5 and 1.0 strength of MS nutrients had high growth rate, and 20-day cutting interval was the best. 72-plug tray was better than 128-plug. Secondly, it was to develop a technique for the production of first-generation seed roots using hydroponics cultivation system. The yield of virus-free plants propagated in the non-insect proof and open-field cultivation was 2,402 kg/10a, 6% higher than those in the insect-proof cultivation, and the rate of virus re-infection was 18% higher compared to 3.3% with insect-proof cultivation. Lastly, it was to investigate the growth performance of virus free plants in farmers' field. Differences were existed in the yield depending on the variety used, but virus free plants showed an increase of $6{\sim}24%$ over virus infected plants.

Purpose: This research suggests a method of establishing criteria for working area and operating cost for a long-term lease of agricultural machinery. Methods: Eight crops were selected-three food crops and five open-field vegetables-and agricultural machines used for sowing, transplanting, and cultivation in dry-field farming were analyzed. Results: The break-even acreage for agricultural machinery under a long-term lease was found to differ by agricultural machine, ranging from 1.0 to 5.8 ha. In terms of arable land area, the break-even acreages for harvesting machinery and transplanters were 15.6 to 26.1 ha and 6.1 to 8.6 ha, respectively. The working area lessees should secure was divided into two cases: (1) 2.0 to 11.6 ha when leasing individual agricultural machines (sowing and transplanting) for a long-term period, and (2) more than 10 ha when farmers who cultivate beans, potatoes, garlic, onions, and so on lease sowing and transplanting machines as a set. When agricultural machinery was leased for a long term, the operating cost and working time were reduced by 27.6 to 74.4% and 2.5 to 21.6%, respectively, indicating considerable effect. Conclusions: A long-term lease project needs to be promoted to overcome the limitation of short-term leases of agricultural machinery. The local government should lead this project and facilitate the mechanization of dry-field farming. The department in charge of agricultural machinery lease projects needs to set the working area to cover the rate and maintenance cost for farmers who lease agricultural machinery for the long term.

Chemical application, one of the most important crop management processes happened to cause spray drift, that would threaten farmers in field as well as dwellers in rural region. Spray drift was affected by micro-meteorological parameters. In Korea, a boom sprayer was introduced but good effects of a boom sprayer was not evaluated. A study to evaluate short distance drift characteristics of a boom sprayer in paddy fields has been undergoing and determining wind characteristics in paddy field was the main purpose of this paper. Micro-meteorological information has been pre-requisite information for evaluating drift in both long and short distances or in both theoretical and experimental ways. Wind velocity, Reynolds stresses, turbulence intensity, skewness, kurtosis etc. were evaluated with height from the ground using a 2-dimensional probe and a hot wire anemometer system.
