  • The effects of cultivation methods (cultivation of curled-shaped type, M-1; conventional cultivation, M-2; growing after treatment with a growth regulator, M-3; cultivation by the combination of M-1 and treatment with oak charcoal, M-4) on the quality characteristics of soybean sprouts were studied by the measurement of growth characteristics. This study also investigated the changes in shelf-life stability of the new soybean sprouts (NSB) using M-4, which was cultivated with oak charcoal and treated with antimicrobial Citrus sunki seed extract. Among the soybean sprouts grown for six days at the high temperature and humidity environment (90$\pm$5% RH, 25$\pm$1$^{\circ}C$), M-1 revealed no significant difference in terms of quality, such as the harvest yield, the rot rate and the growth characteristics when compared with M-2. M-3 showed no significant difference in growth characteristics, of hardness, and sensory evaluation scores when compared with the soybean sprouts grown by conventional methods. NSB had a low number of total microorganisms and had a better appearance after five days of storage than did the control group (M-2). These findings demonstrate that chemical-free and clean soybean sprouts can be grown by combining oak charcoal and antimicrobial Citrus sunki seed extract, thereby meeting the consumer demand for safe, chemical free sprouts.

  • 저투입생산환경에서 콩 재배가 토양미생물군집활성도에 미치는 영향에 대한 결과는 다음과 같다. 초기 비료 및 퇴비 투입 후 유기물은 재배기간 내내 콩을 재배한 화분이 감자를 재배한 화분보다 높게 나타났으며, 토양 중 인산은 콩을 재배한 토양에 비해 감자를 재배한 토양에서 다소 높은 경향을 보였다. DHA 값은 콩을 재배한 토양이 생육기간 전반에 걸쳐 감자를 재배한 토양보다 유의하게 높게 나타나 토양미생물 활성도가 콩을 재배한 토양에서 증가됨을 알 수 있었고, 이러한 결과는 콩을 재배한 토양의 유기물함량 증가에도 영향을 미친것으로 판단된다. DGGE로 토양미생물군집을 분석한 결과 Proteobacteria 문(phylum)에 속하는 미생물들이 공통적으로 확인되었으며, 감자를 재배한 토양이 콩을 재배한 토양보다 다양한 미생물이 동정되었다. 또한, 콩 재배 토양의 높은 토양미생물활성도는 콩 재배 시 형성되는 소수의 특정한 미생물들에 의한 영향으로 판단된다.

  • This study was conducted with two objectives ; one was to select the suitable soybean cultivars for cultivation in paddy field and the other was to establish the environment-friendly rotational cropping system of soybean instead of rice in paddy field. In order to evaluate growth adaptation and yields, Eve soybean cultivars were cultivated in Yeoncheon, Keonggi province, with two cultivation methods such as level row and high ridge. Growth of the top plants, such as stem length, number of branches, diameter of stem, were higher in high ridge than in level row, however, the differences among the cultivars were bigger than those between the cultivation methods. Dry weight of top plant was significantly different among the cultivars during whole growth stages, however, it was higher in level row than in high ridge at V5 stage while it became higher in high ridge as growth progressed. Roots were more developed in high ridge than in level row during whole growth stages. T/R ratio in level row was higher than that in high ridge. During whole growth stages, significant differences were observed among the cultivars in growth and yields in each cultivation method and yields of Eunhakong was the highest. In results, number of nodules and T/R ratio at V5 stage, number of pods at R2 stage, and number of seeds and T/R ratio at R5 stage had highly correlated with yields, respectively.

  • This study was conducted to determine the optimum number of inter-rows according to distance of drainage furrow (DF) for running-off excessive-water stress (EWS) in paddy field. The most soil water potential was shown in high ridge (distance of DF by 70 cm) cultivation and the soil water potential showed increasing tendency in over four inter-rows cultivation by DF. The growth of soybean reduced by extended inter-row and its reducing level was high, especially, over four inter-rows (DF distance by 2.8 m) because of EWS. The photosynthetic rate decreased in the more extensive field by distance of DF at V5 and R2 stages, especially, in over four interrows cultivation. Also, root activity decreased at wider DF. The yield was reduced with wider distance of DF more extensively, the highest yield of 270 g per $m^2$ at the every row, but yield showed decreasing tendency at over the $4^{th}$ row (2.8 m) cultivation. Soybean cultivation in paddy field could be founded with DF of every other or $4^{th}$ row.

  • Owing to adverse weather conditions, there is a heightened focus on actively researching the regulation of the sowing date in field crop cultivation. Soybean, a prominent field crop with extensive acreage and production, is a photophilic and thermophilic crop characterized by short-day photoperiodism. Identifying the optimal sowing time is crucial for mitigating the effects of severe weather conditions on soybean yield. Precise control over the timing of soybean sowing is the key to minimizing yield reduction due to unfavorable weather conditions. Temperature, photoperiod, and their interplay are the most significant factors influencing soybean cultivation among various weather factors. We conducted an experiment using three Korean soybean cultivars with varied maturities (Hwangkeumol: early maturing and Daewonkong and Pungsannamulkong: late maturing) in 2013 and 2014. Our investigation covered aspects of soybean growth, development, yield components, isoflavones, and visual seed quality. Across all three varieties, isoflavone levels increased with later sowing dates, while other measured components exhibited significant variations based on the sowing date. This study also provides valuable insights for the selection of suitable cultivars that perform well in soybean cultivation at various durations of maturity.

  • According to the literature, soybean cultivation originated from Wang-Gong (B.C. 685-643) of China who brought it from northeast Asia, for the first time. FUKUDA, of Japan divided soybean into three species-the wild, the cultivated and the intermediate. From the result of that study, he concluded that the soybean originated in northeast Asia. But Wang Kum Rung of China insisted that soybean originated in Hwa-Nam, because the soybean is a shortday plant and the agricultural history of Hwa-Nam, south of China, is older than that of northeast Asia. However, agriculture in northeast Asia had been already begun about B.C. 4000-6000 and the origin of culture cannot be decided only by photosensitivity. It has been proved that soybeans found in Korea were same as the ones of B.C. 2000. The soybeans of northeast Asia meet the conditions of the probable place of origin of cultivated crops established by Vabilov. Accordingly it is concluded that soybean has been originated from northeast Asia.

  • 점무늬병은 콩에서 최대 50% 정도의 수량감소가 보고된 병으로 최근 한국 콩 재배포장에서 큰 문제로 대두되고 있어 최근 6년간의 보급 품종을 대상으로 콩 점무늬병에 대한 저항성 검정을 실시하였다. 표준화된 검정방법을 적용하기 위해 가장 효과적인 포자 형성 배지 조건을 탐색하고 저항성 검정 평가 기준을 확립하였다. 포자형성은 $25^{\circ}C$, 12시간 광 조건과 암 조건에서 V8 juice를 이용한 배지의 포자 형성이 가장 효과적임을 알 수 있었다. 접종은 $10^5spores/ml$로 준비하여, 제 5 복엽 완전전개기인 V6 stage까지 키운 건강한 콩 식물체에 실시하였고 병 반응은 28일 동안 관찰하였다. 그 결과 대풍은 8개 균주 모두 저항성을 보였고, 신팔달2호는 7개 균주에, 연풍, 청아는 6개 균주에 저항성을 보였다. 반면에 황금, 태광, 대원, 천상, 신화 등은 평가한 8개 균주에 모두 감수성 반응을 나타내었다. 콩 점무늬병에 대한 저항성 품종을 육종하기 위해 표준화되고 정밀화된 저항성 검정방법과 판정 체계를 갖추는 것은 매우 중요하며 이 방법은 차후 포장 저항성 검정에도 적용할 수 있을 것이라 기대한다.

  • In this study, the characteristics of soybeans with different cultivation methods depending on their origins and the properties of tofu made from these soybeans were studied. The isoflavone content was higher in the general Korean soybeans compared to the organic American soybeans. There were no significant differences among the Chinese soybean samples, so the cultivar method was considered to have a greater effect on the isoflavone contents rather than the cultivation method. The protein contents were higher in the tofu made from the general Chinese soybeans and the organic Korean soybeans. Furthermore, the tofu made from the organic Chinese soybeans contained the least amount of proteins. Isoflavone contents were not significantly different among the samples. Texture profile analyses consisting of hardness, cohesiveness, adhesiveness, springiness, and gumminess were all shown to be higher in the organic tofu than in general tofu, with the exception of adhesiveness. In sensory evaluation, color and texture were significantly different according to the samples, and the differences were found to be affected more by the origin of soybeans rather than the cultivation methods. According to this study, the physicochemical properties of the soybeans and tofu seemed to be influenced by the cultivation region rather than the methods.
