경관작물은 봄부터 늦은 가을까지 도로변, 하천변, 화단에 재배되어 우리 주변 환경을 아름답게 꾸며주는 역할을 수행하였으나 최근에는 대면적의 농경지에 재배되면서 넓은 면적에 재배가 가능한 작물들이 각광을 받기 시작하였다. 따라서 여름에 재배되는 작물 중에서 경관작물과 녹비작물로 이용 가능한 작물을 선발하고자 해바라기, 코스모스, 네마장황, 네마황, 세스바니아, 수수의 작물 생육특성, 녹비수량 및 질소생산량을 조사하였다. 경관작물의 초장은 수확시기가 늦을수록 증가하였으며 특히 네마장황, 코스모스, 해바라기, 수수는 100 cm 이상으로 컸다. 네마장황과 코스모스의 개화소요일수는 각각 50일, 53일로 짧아 가장 빨리 개화가 시작되었으며 개화기간은 50일 이상으로 길었다. 해바라기는 개화되는데 52일이 소요되어 짧았으나, 개화기간이 21일로 짧았다. 녹비수량과 질소생산량은 모든 작물에서 수확시기가 늦어질수록 증가하였다. 녹비수량은 네마장황, 수수, 해바라기에서 $7.2{\sim}7.5Mg\;ha^{-1}$로 가장 많았고 세스바니아에서 가장 적었으며, 질소생산량은 네마장황에서 $168.1kg\;ha^{-1}$으로 가장 많았다. 따라서, 개화특성, 녹비수량, 질소생산량을 기준으로 볼 때 여름용 경관작물 중 네마장황이 녹비와 경관 효과가 가장 우수하였다.

Although it is not a landscape crop according to MIFAFF(ministry of agriculture, food and rural affairs), yellow mustard is considered a superb landscape crop because of its growth and flower characteristics. We sowed yellow mustard as a landscape and green manure crop in upland soil (four types of soil texture) in spring. And we studied its flowering characteristics, dry weight, and nitrogen yield. The growths of yellow mustard were possible in every soil ranging from sandy soil to clay loam. Its height was 54.1 ~ 76.1cm and the number of node per hill was 11.3 ~ 17.0. Its flowers had a light yellow. It took about 44 ~ 50 days to flower, and flowered for 22~25 days. The dry weight of yellow mustard was $2.27{\sim}3.60tonha^{-1}$ with highest in sandy loam and loam. Among the nutrients of yellow mustard, nitrogen(T-N) was $12.6{\sim}20.8gkg^{-1}$, and C/N ratio was 21.6~37.7. The nitrogen yield of yellow mustard was $35{\sim}62kgha^{-1}$. In conclusion, because of its flowering characteristics and dry weight, yellow mustard was considered appropriate for both green manure and landscape crop uses.

With increasing public concern for environmentally friendly agriculture, ecological aspect of landscape management is of growing importance. AHP (Analytical Hierarchy Process) analysis were conducted based on the delphi survey of 31 experts to evaluate the relative importance and the preference of landscape elements. Landscape components of organic farmland were classified into 2 landscape fields, 5 landscape types, 14 landscape units, and 37 landscape elements. Overall relevance score for the proposed landscape components were about 5.5 on the seven point scale. While the relative importance weight of cropland landscape field was 0.71, the weight of intra-structure landscape field was 0.29. Among the cropland landscape, relatively higher weight was assigned to farming system (0.47) and margins (0.31), as compared with hydrological system (0.22). In the farming system, crop (0.40) and farm land (0.39) were the most important landscape units. In the margins, higher weight was given to Buffer zone (0.44) and Trees (0.42). Biological habitat (0.43) ranked the highest score in the hydrological system. Preferable landscape elements were glass house, companion plants, rice paddy field, diverse crop species, small pond, and small river, which are representing ecological advantage of organic farming systems. This result indicated that the landscape elements identified in the study would be suitable to evaluate ecological aspect of rural landscape in organic farmland.

The direct payment program for rural landscape conservation in practice since 2005. Recently it is the policy or plan of direct payment for rural landscape conservation attracts great interests as they may help rural people who are very disadvantaged. This paper presents the status of the direct payment program for landscape conservation in rural area and proposed improvements to the program as following; 1) to diversify the plant species, 2) to include other rural elements than plants, 3) to enlarge the areas of crop plantation, 4) to simplify and clarify application process. We sampled two pilot programs, one of spring flower crop and the other of autumn flower crop, and questionnaire surveyed visitors, local government officers and farmers in order to find problems and suggest improvements.

The green manure crops are returned to soil when the plants are still green. The green manure crops play a role in reducing chemical fertilizers, improvement of soil fertility, reduction of soil erosion, weed control, and landscapes effect. Typical green manure crops are barley green manure, hairy vetch, chines milk vetch and clovers. We sowed 49 species of green manure crops in upland soil to increase the usage of green manure crops. We searched the effectiveness of green manure yield, C/N ratio, soil mulching, and landscape effect. The green manure crops that have $5tonha^{-1}$ or more of green manure yield (fresh weight) were 6 gramineous crops, 4 leguminous crops, and 3 others. Green manures yield in a short growth period was higher in gramineous crops than leguminous crops. Among the green manure crops, 3 gramineous crops, 12 leguminous crops, and 3 others were under 25 in C/N ratio. Seven gramineous crops, 8 leguminous crops, and 5 others were over 50% of soil covering rate. Green manure crops that have beautiful flowers were in total 16 kinds, such as 4 gramineous crops, 6 leguminous crops, and 6 others. In result, based on green manure yield and C/N ratio, excellent species in the green manure crops were 4 species (triticale, 2 kinds of hairy vetch, and lupin). Green manure crops that were effective at soil mulching were 20 species, like hairy vetch, oats, sorghum, phacelia, buckwheat, etc. Buckwheat, crotalaria, mustard plant, phacelia, and etc. could be available for landscape crops.
