  • The purpose of this study is to analyze the effect of crop diversification on farm households' agricultural income. Abundant literature have explored the determinants and efficient strategies for crop diversification. Yet, there is a paucity of research studies that empirically test the effectiveness of crop diversification as a profitable farm management strategy. Utilizing the 2015 Agricultural Census, this study adopts a quasi-experimental research design to compare the outcomes between farm households that opted for crop diversification and farm households that did not engage in such a strategy. In doing so, this study applies the Heckman Selection Model and the decomposition technique to address the problem of selection bias and to identify the causal effect. Our empirical results show that farms that implement diversification are more likely to earn higher agricultural income than non-diversified farms, although the difference would not be much substantial. This study concludes with several policy proposals to stabilize agricultural income in conjunction with crop diversification.

  • This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

  • The purpose of this study was to explore a paradigm for the development agricultural cooperative unit in Korea. To fulfill the purpose of the study, both a review of literature and case studies was used. The agricultural cooperative units selected for the survey were Doduram Swine, Songtan Cooperative Organization, Okyung Cooperative Farms, and Harim Poultry Company. To identify major factors and limitations associated with effective management of agricultural cooperative units, selected cooperative units for production, processing and marking were surveyed and analyzed. This study identified four major factors to be included in a development paradigm of effective agricultural cooperative units which were: 1) active participation of farmers, 2) techniques end attitude of participants, 3) horizontal integration of a high technology enterprise with agricultural production, and 4) increasing cooperative work on production and marking within the unit. Based on the results of the study, the following recommendations were made for further improvement and development of agricultural cooperative units : First, farmers should be encouraged and motivated to participate actively in agricultural cooperative units. Second, participants of the agricultural cooperative units should be equipped with both technical knowledge and skills on agricultural production, processing and marking. Third, a national net-work system should be established for the agricultural cooperative units throughout the country. Fourth, agricultural cooperative units should be expanded to various agricultural sectors covering wider area. Finally, agricultural cooperative units should be supported by farmers, agricultural organizations and the government for more effective management and further development.

  • Summer cabbages in an alpine area are very sensitive to the fluctuations in supply and demand. Yield variability due to weather conditions dictates the market fluctuations of cabbage price. This study reports an empirical relationship based on weather conditions to estimate the growth and harvestable biomass of cabbages, factors that are critical for supply of summer cabbages. Based on experimental results testing sowing date effects over the two years from 1997 to 1998, a logistic equation was parameterized to predict leaf area expansion of summer cabbages. This logistic model for leaf area expansion was then combined with an empirical allometric relationship to predict total biomass. The final equation for estimating fresh weight accumulation of Chinese cabbage is given by: $$Fresh\;weight=3500/(1+{\exp}(5.175-1.153{\times}(6/(1+{\exp}(6.367-0.0064{\times}PHU)))))$$ Where PHU is potential heat units ($^{\circ}C$). The model performance was tested using weather data from 2003 to 2006 to predict fresh harvestable biomass. Overall the model performance was satisfactory with the correlation efficient ranging between 0.89 and 0.94 for each year.

  • 우리나라의 농업은 주곡의 지속적인 자급기반을 마련하고 이제 단순한 농사형태에서 벗어나 새로운 소득작목을 개발하고 합리적인 경영개선을 통하여 소득을 높이는 상업농시대에 접어들게 되었다. 따라서 상업농시대에는 농업도 새로운 기술을 바탕으로 질 높은 농산물을 안정적으로 생산공급할 수 있는 기술의 확보가 더욱 요구되고 있다. 최근 농산물수입개방 시대에 접어들게 되면서 우리 농산물도 국제경쟁력향상을 위한 품질향상 및 새로운 소득작물의 개발이 절실히 요구되는 시점에 와있다. 여러 지방지치단체에서 그 지방에 알맞은 소득작물을 개발하여 많은 소득을 올리고 있는 사례를 많이 볼 수 있다. 예로서 보성의 녹차, 무안의 무화과, 구례의 오이 등이 대표적인 예라고 할 수 있다. 여러 농업연구기관에서도 과학적인 토양연구로 세부정밀토양조사를 실시하고 작물재배의 부적지에 대해서는 토양개량방법을 연구하고 있으며 그에 따른 시비추천과 소득작물의 적지적작추천을 하고 있다. 국내에서도 GIS의 발전 및 RS의 발전과 더불어 친환경농업의 일환으로 정밀농업분야에 많은 관심이 집중되고 있다. 정밀농업은 농업생산기술 분야에서 아직 생소한 접근방법으로서 여기에서는 지구측위시스템(GPS)와 지리정보시스템(GIS), 원격탐사(RS)기법들이 많이 응용되고 있다. 또한 농업의 1차(식량생산)적인 목적에서 2차, 3차(소득증대 및 부가가치 증대)적인 목적으로 변화되고 있다. 각 지자체에서 그 지역에 적합한 농산물 재배를 위한 재배단지 확산방안 연구가 진행중에 있으며, 과거 토양속성인자를 가지고 재배적지 선정을 해왔으나, 본 연구에서는 GIS와 RS을 중첩하여 적지선정에 관한 최적의 시스템을 구현하였다. 이런 적지 선정을 통하여 유기농업의 실현을 도모하여 소비자의 욕구에 맞는 작물 생산 및 농촌관광단지 조성을 통해 부가가치증대 및 소득증대를 꾀함으로 농촌문제 해결에 도움이 될 것으로 기대된다. 본 연구를 통해 GIS 와 RS의 기술이 농촌분야에 더 효율적으로 적용될 것으로 기대되며, 농업기술센터를 통한 정보제공을 함으로써 대농민 서비스 및 농업기관의 위상이 제고 될 것으로 기대된다.

  • This research was carried out to investigate the shoot growth characteristics and climatic factors for early harvest and stable yield by greenhouse on mulberry ($Morus$ $alba$) in Buan-gun, Jeollabuk-do. Budbreak and coloring date of mulberry in greenhouse were earlier 18~19 days than those in field, and from bud-break to coloring was 39 days in both cultivation types. Shoot length and fruit number per shoot of mulberry in greenhouse were not significantly different with those of field, but number of node was significantly little than that of field. For 39 days in greenhouse, weekly cumulative radiation were 0.3~0.8 times. But weekly cumulative temperature was not different with that of field. And relative humidity as range of 53.0~94.5% in greenhouse was higher than that of field. Therefore, mulberry is suitable to greenhouse cultivation for early harvest and stable yield.

  • The objective of this study was to analyze the factors regarding work-related musculoskeletal disorders (MSDs) in fruit-growers and offer the fundamental data for work improvement. The 587 fruit-growers (409 males and 178 females) working with 5 kinds of fruit: apple, pear, peach, grape, and mandarin participated in a questionnaire survey regarding MSDs and health condition in 2004 and 2005. The results are as follows: 1. Smoking rate was highest in apple growers. 2. Drinking rates were highest in male peach growers and in female grape growers. 3. Regular exercise rates were higher in pear and mandarin growers. 4. Physical and mental fatigue was higher in females than in males in most cases. 5. The prevalence rate of medically diagnosed diseases was highest for osteoarthritis (16.4%), herniated nucleus pulposus (HNP, 13.5%), and chronic gastritis/gastric ulcer (10.5%). As well as, the prevalence of dermatosis was higher in pear and mandarin growers. 6. The prevalence rate of musculoskeletal symptoms among the various pain areas was highest for lower back, shoulders, and knees. The prevalence rate was also high for lower back, shoulder, and knee pain in apple and grape growers. 7. The significant indexes used determining the musculoskeletal symptoms were BMI, working period, and regular exercise. These results can be practically used for work improvement for the fruit-growers to prevent MSDs.

  • The present study aims to determine the effect of the prevention exercise program of musculoskeletal disorders developed for apple and pear farmers. To achieve this goal, 25 farmers who have subjective symptoms in the musculoskeletal system (Criteria 1 in the National Institute for Occupational Safety and Health) have conducted the prevention exercise program for 12 weeks from April 7, 2011 to July 1, 2011. As a result, the prevention exercise program of the musculoskeletal disorders for farmers in the fruit growing industry have improved physical capability of them (upper extremity endurance, lower extremity endurance, balance and agility) as well as a quality of life effectively. In addition, a quality of life showed a significant correlation with Oswestry Disability Index, and Psychosocial Well-being Index. For the future study, various studies are expected to develop and apply exercise programs in consideration of the characteristics of farming work.
