  • This study was carried out to identity the effects of antifungal bacteria isolated from the soil grown kiwi fruit plants on the growth inhibition of Botrytis cinerea causing gray mold in kiwi fruit plants in the southern districts of Jeonnam. Two hundred and fifty antagonistic microorganisms were isolated and examined into the antifungal activity against Botrytis cinerea. We screened and isolated four bacterial strains which strongly inhibited Botrytis cinerea from the soil grown kiwi fruit plants. And the best antifungal bacterial strain which called CHO 163 was finally selected. Antagonistic microorganism CHO 163 was identified to be the genus Bacillus sp. based on the morphological and biochemical characterization. Bacillus sp. CHO 163 showed 86.9% of antifungal activity against Botrytis cinerea. By the bacterialization of culture broth and heated filtrates of culture broth, Bacillus sp. CHO 163 showed almost all of antagonistic activity against Botrytis cinerea. And we also confirmed that in vitro the treatment of Bacillus sp. CHO 163 cultured by SD+B+P broth efficiently controled the growth of Botrytis cinerea causing gray mold in kiwi fruit plants.

  • 국내 하천, 호소에 유입되는 오염물질 중 30% 이상이 농업 활동 등으로부터 기인한다. 정부 부처는 '04년부터 농업 비점오염원 저감 대책을 수립·시행하고 있으나 농촌 인구 고령화, 열악한 재정환경, 관행화·고착화 된 농법 등으로 인해 주민참여 및 대책 적용의 한계가 있었다. 금호강 상류 보현산댐 유역은 대부분 임야로 고현천 등 상류 하천변에 사과원이 밀집되어 있다. 또한, 유역면적이 32.16km2로 좁고, 유로 연장 5km 이내로 짧으며 하천 경사가 급해 강우시 토양 유실량이 많고 유출속도가 빠르다. 이러한 유역 특성상 상류 사과원은 '16년 보현산댐 담수 이후 매년 반복적으로 발생하는 녹조 등 수질 문제를 초래하는 주요 비점오염원으로 지역사회 이슈가 되었다. 이에 따라 K-water는 낙동강수계관리위원회 환경기초조사사업의 일환으로 지역주민들과 논의를 통하여 댐 상류 사과원에 친환경농법(심층시비)를 적용하고 수질 개선 효과를 분석하였다. 심층시비는 과수 주변 토양 천공 후 퇴비를 시비하는 친환경농법으로 표층시비에 비해 초기 강우유출 오염물질량을 저감하고 퇴비 사용량도 줄일 수 있다. 금번 연구에서 실제 운영 중인 농지('19년 24천평, '20년 27천평)을 대상으로 심층시비를 시범적용한 결과, 퇴비 사용량은 표층시비의 50% 수준으로 감소하였고 과수 생육 및 품질에는 큰 영향이 없는 것으로 나타났다. 강우 시 유출농도는 표층시비 대비 TOC 5.0~41.3%, T-P 4.0~57.3% 감소했다. HSPF 유역 모델링 분석 결과, 전체 과수원 중 70% 농지에 심층시비를 적용한 경우, 하절기 유역 T-P 유입부하량이 5.0~6.8%(소유역 최대 28.2%) 감소하는 것으로 예측되었다. 본 연구결과를 바탕으로 심층시비를 확대 적용하고 유역 수질관리에 기여하고자 한다.

  • For agriculture is very highly dependent on climate and weather condistions, global warming seems to have a great impact on it, including its productivity, cultivation condition, product quality, and optimum cultivation location. In this study, we adopted geographical information system (GIS) in order to investigate the changes of Korea's cultivation area which are caused by global warming, especially with the examples of such tropical and sub-tropical fruits as lemon, fig, kiwi, orange, pomegranate, and mandarin. In terms of GIS techniques, we utilized the interpolate function for temperature changes, surface analysis function for slope, and raster calculator. Currently, these fruits's cultivation areas are in Jeju island and southern part of Korea. But these areas will be expanded according as our GIS model assumes $3^{\circ}C$ and $4.5^{\circ}$ increases of average and lowest temperature by the global warming in Korea. Optimum cultivation areas of these six fruits have two patterns; one is expansion and the other is belt shape shift. From the results of the study, we call for an urgent need of Korea government's policy and farmers' reasonable responses about global warming, which will be able to give more opportunities and better foods to Korea society in general.

  • Since 1995, agropolitan cities have been created, in order to pursue the balanced development between urban cities and its surrounding rural counties. However, the inequality of regional level that was caused by indiscreet development has become the ever-serious problems recently. Therefore, this study aims to analyze regional characteristics and patterns for setting up the sustainable spatial planning. Firstly, the regional characteristics were summarized by five factors; development-oriented factor, agricultural factor, living environmental factor, rice growing, fruit gardening factor. The regional patterns were classified with five patterns using cluster analysis; orchard farming, farming of medium and small size, small stagnation, under urbanization, mixed urban-rural properties, and industry of southeastern seashore. Accuracy of the results by discrimination analysis showed that pattern II, V, and VI were confidence level of 100%, but the others had nearly 90% confidence level.

  • In order to get the actual pesticide usage data for fruit crops at farmer's gate, this survey was carried out on the growers of 6 representative fruit crops such as apple, citrus, grape, peach, pear and persimmon, in Korea. One hundred fifty farmers were selected in main production areas to record their pesticide usage during the growing seasons. Pesticides were sprayed in pear 15.2 times/year and persimmon 7 times/year. Pesticide input amount per unit for fruits was 39.5 for citrus, 22.1 for apple, 21.5 for pear, 11.9 for peach, 10.8 for persimmon and 6.7 a.i. kg/ha for grape, respectively. The amounts of pesticides sprayed in 2002 except for peach and pear tend to decrease compared with those in 1999. The major fungicides used were mancozeb, propineb, dithianon, etc., while the major insecticides were fenitrothion, chlorpyrifos, methidathion, etc. Total active ingredients of pesticides used for six fruit crops amounted to 18.3% of total sales amount of pesticides for horticulture in 2002. The amounts of pesticides sprayed on citrus, grape, peach and pear in Korea was less than those in U.S.A., excepting those in apple.

  • The aim of this paper is to explore the role played by the endogenous farming organization sustaining rural community's competitiveness. Nulmi-Ri, Chungdo Kun in Kyongsangbuk-do chosen as a case study area is known to be one of the most competitive rural communities, making a living with a peach farming. This community maintains its competi- tiveness by operating a community-based filming organization which was organised in an endogenous way. Most of individual farmers in this community belong to the farming organization and they have cooperative relationships in the processes of production and distribution. In this respect, the exchange and circulation of knowledge, and collective learning, tend to be significantly taken place between the organization members. Based on the experience of the Nulmi-Ri's endogenous farming organization, we propose some constructive comments for rural community development.

  • 경남 및 전남지방은 산업에 있어서 농업의 비중이 상대적으로 큰 지역이다. 두 지방의 농업의 특성은 큰 차이는 없으나, 전남 지역이 농가인구, 호당 경지면적이 넓다. 영농 형태별로는 전남 지역이 수도, 전작의 비중이 크며, 경남지역은 과수, 채소, 화훼, 축산 등 소득작목의 비중이 높다. 농업기반에 대하여 보면, 농업진흥 지역비율은 경남 53.7%, 전남 64.8%이며 수리답율은 81.9% 76.1%, 경지정리율은 76.1%, 68.4%로 경남지역이 유리한 기반을 갖고 있다. 작목별 특화도를 보면 경남 지역은 맥류, 서류, 앙파, 마늘, 감, 화훼류 등이 높으며, 전남 지역은 맥류,두류, 마늘, 양파, 감, 참깨 등이 높게 나타나고 있다. 지역내 수급현황을 보면 경남지역은 미곡, 두류, 무, 배추, 고추, 사과, 포도, 복숭아 등이 부족하며, 서류, 마늘, 양파, 배 등이 과잉이고, 전남지역은 대부분이 과잉이며 사과, 포도, 복숭아 등이 부족하다. 지역간 농업협력은 상호 과부족인 농산물의 교역이나 비교우위가 있는 작목에 특화함으로써 서로 이익을 누리는 방안과 타 지역이나 해외 진출에 있어서 공동보조를 취하는 것으로 생각할 수 있다. 이에 대한 구체적 빙안으로서는 무엇보다 양 지역농업 및 농민에 대한 상호 이해가 이뤄져야 하며, 이를 전제로, 지역별 비교우위가 분명한 품목에 대하여 상호 우선적으로 구매할 수 있도록 하는 등 상호 교역을 지원하며, 농산물 수급 불균형으로 인한 가격파동을 예방하기 위하여 계획생산, 계획 유통이 불가피한 만큼 농협, 농민단체, 지방정부간의 농업정보의 공유와 조정 채널을 구축하고, 지역간 직거래 활성화하고 서로의 이해를 돕기 위한 농산물 장터 등 장소와 기회를 제공하며, 해외수출 시장 개척을 위한 공동 노력, 농업기술의 상호 교류 등이 필요하다.

  • Animal pollination is an important ecosystem service provided mostly by diverse insect groups such as bees and hover flies. Maintaining agricultural productivity and securing the nutritional balance are closely tied to human wellbeing. This study aimed to estimate the pollination dependent food production in Korean agricultural system. Crop production data were obtained from Korean statistical information service (KOSIS) data of 2015. By implementing pollination dependency, crop production and market price, contribution of insect pollination to crop production increase were estimated from total 71 crops including 12 cereals, 19 fruits, 18 field vegetables, 13 greenhouse vegetables and 9 specialty crops. Mean pollination dependency of all crops were 29.2% and it was higher on fruits, specialty crops and greenhouse vegetables as well, but low (7.5%) in cereal crops. Pollination dependent (PD) production was estimated as 17.8% of total agricultural crop production with the economic value of 6,850 (6,508-7,193) billion won. Especially, PD production of greenhouse vegetables accounted 49.2% followed by fruits of 42.9%. Even specialty crop also showed higher PD production (35.9%). It was obvious that pollination is the vital service for agricultural production as well as nutritional security in Korea. Further protection and enhancing the pollination service were discussed with integrated pollinator-pest management (IPPM) strategies.
