  • 김치는 절임 발효 식품으로서 염장이 품질에 영향을 미치는 중요한 요인이다. 이러한 영향에 대해 주재료인 배추의 품종 및 재배 방법의 차이를 구명하고자하였다. 배추의 재배방법(노지, 하우스재배) 및 품종(쌈노랭이, 매력, 춘황, 춘광, 고령지 여름, 옥황씨알)에 따른 수확전 요인(생육 특성)과 수확후에 나타나는 절임특성을 조사하고자 구중, 결구지수(크기), 엽수, 엽두께, 삼투몰 농도, 염함량, 탈염률, 경도를 측정하였다. 수확후 생육면에서는 시설내의 하우스에서 재배한 배추가 구중 및 결구크기, 엽두께, 함수량 등 면에서 높은 경향을 보였으며, 품종에 차이는 보이나 전반적으로 노지에서 재배한 배추의 경도, 삼투몰 농도가 높은 경향을 보였다. 배추를 절임시 염함량은 재배방법과 그에 따른 품종에 의해서도 차이가 나타났는데, 탐염률이 낮은 것들에서 염함량이 다소 높은 경향을 보였으며, 삼투몰 농도에서도 비슷한 경향을 보였다. 본 실험의 결과 동일한 품종이라도 재배 방법의 차이에 따라 배추를 절였을 경우 나타나는 특성이 달라질 수 있음을 확인하였다. 배추는 주년 생산작물이므로 봄철뿐만 아니라 앞으로 다른 생산시기도 확인이 필요 할 것으로 생각되며 이러한 재료의 차이에 따라 김치를 담갔을 때 대한 나타나는 고찰이 보다 필요 할 것이다.

  • The objective of this study is to decide a spatial interpolation method on temperature data for the suitability analysis of garlic cultivation. In Korea, garlic is the second most cultivated condiment vegetable after red pepper. Nowadays warm-temperate garlic faces potential shift of its arable area according to warmer temperature in the Korean Peninsula, and the change can be drawn with the precise temperature map derived from interpolation on point-measured data. To find the preferable interpolation method in cases of germination and vegetative period of the garlic, different approaches were tested as follows: Inverse Distance Weighted (IDW), Spline, Ordinary Kriging (OK), and Universal Kriging (UK). As a result, IDW and UK show the lowest root mean square errors as for the germination and vegetative seasons, respectively. However, statistically significant difference was not revealed among the applied methods regarding the germinating period. Eventually this will contribute to mapping the suitable lands for the cultivation of warm-temperate garlic reasonably.

  • 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.

  • 백수오 지주설치 생력화를 목적으로, 무지주 처리방법을 달리하여 백수오 중국도입종을 재배하고, 이에 따른 생육, 근수량 및 경영비를 검토한 결과를 요약하면 다음과 같다. 1. 관행 지주재배시 무지주 재배에 비해 생육이 양호한 경향이었으며, 무지주 처리 간에는 주만장과 주경의 총만장은 무처리, 적심, 선단예취 순으로 긴 반면, 경태는 선단예취, 적심, 무처리 순으로 굵었다. 선단예취시 엽수는 가장 적었으나 잎이 크고 엽당 무게가 무거운 편으로 이는 덩굴의 선단부 예취로 인해 수광면적이 확대됨으로써 광합성능률이 향상된 것으로 판단된다. 2. 지근의 수와 주근태는 지주재배와 선단예취에서 다소 많거나 굵었고, 주근장과 지근태는 지주재배와 적심 처리에서 길거나 굵었다. 3. 10a당 생근수량은 관행 지주재배시 1,918kg에 비해 무지주 재배시 $17.9{\sim}22.6%$ 감수되었으나, 지주생력화로 생산비가 감소됨으로써 경영비가 절감되어 소득이 $8%{\sim}17%$ 증가되었다. 무지주 처리방법 간에는 무처리에 비해 선단예취시 생근수량은 6%, 소득은 8% 각각 높았다.

  • Recently agricultural situations are being placed in unfavourable socio-economic environment as followed by rapid decrease of rural population, poor labor quality and high wages of rural society due to high speedy industrialization of social structure in Korea. In addition to those circumstances, under the UR system to be expected in the early future, free trade of agricultural products will be faced inevitably in Korea. Practically prices of rice as a principle food in this country are expensive about three times compared to those of foreign rice markets, and so how to increase the international competitiveness and food supplies are important problems to be solved rapidly. Accordingly an urgent goal is reduction of agricultural production cost by the improvement of labour productivity as a labour saving and cost down cultivation methods as the direct seeding cultivation in rice. But there are many problems in the direct seeded rice cultivation. The important things to be improved in that cultivation are development of rice varieties with lodging tolerance, effective seedling stand, weed control, irrigation management and fertilizing and so on. Moreover agricultural basis as irrigation facilities, land consolidation and farm machineries must be improved for the stability of rice cultivation in the future.

  • This studies were conducted to investigate the growth responses and yields of Astragalus membranaceus Bunge which were grown with organic cultivation using two organic fertilizers and two green manure crops of hairy vetch and rye in 2008 and 2009. The lengths of stems and roots were not clearly different between organic and conventional cultivations. The root diameters and the branch numbers were slightly thicker and more in all treatments of organic cultivation than that of conventional cultivation in 2008, although they were not significantly different between two cultivating methods in 2009. The dry weights of shoot and root were heavier on organic cultivation than those on conventional cultivation. The T/R ratios were commonly higher in organic culture, showing more clearly in 2008 than 2009. The yields were generally higher in organic cultivation than those in conventional cultivation in 2008 although the effect did not clear on yield in 2009. The organic cultivation using of organic fertilizers and green manure crops would be new method to have safety and qualitative products. The techniques of organic cultivation for Astragalus membranaceus Bunge would be studied more on utilizing the natural organic resources.
