After free trade, it is increasing to import crops, aquatic products, and livestock which are produce in a foreign land. But it is affect negatively to trust relationships and markets of Jeju's foods because of breaking it out that foreign productions exchange domestic. Therefore, this paper designed and implemented the Genuine Quotation system of Black pigs using UHF RFID. This system is developed for distinguishing spuriousness, then searching information of the product through EPC ONS in EPCIS to print within a screen. Moreover, this intuitional and efficient system is constructed by connecting various sensors and lights. It can be contributed income increase thorough the security for the quality authority of the agricultural & stockbreeding products with FCS, FCG Certificate and the genuine certificate of the black pig which is the one of most typical agricultural & stockbreeding products in the pure Green Province, Jeju.

The purpose of the study is to investigate factors influencing the adoption of environment-friendly agriculture in greenhouse vegetable production of Jeonnam province. An interview survey were conducted during 2008, including six counties: Gwansanku of Gwangju, Gwangyang, Goheung, Damyang, Boseong, and Suncheon. Major crops grown in surveyed area were green peppers, cucumbers, strawberries, cherry tomatoes, tomatoes, and watermelons. Logit model results show that adopters of environment-friendly agriculture are more likely to participate in extensional education programs, attend educational programs on environment-friendly agriculture, have greater cultivated acreage, and have larger agriculture-only-designated farmland. However the adopters are less likely to have greater number of family members participating in farming, and live Goheung county. Efforts should be made in extensional education programs to lead more vegetable growers to adopt environment-friendly agriculture. Policy makers' additional efforts should be followed to increase adoption rate of environment-friendly agriculture in lower adopted areas.

Nitrogen (N) is an essential macronutrient required for plant growth and crop production. However, N in soil is usually insufficient for plant growth. Thus, chemical N fertilizer has been extensively used to increase crop production. Due to negative effects of N rich fertilizer on the environment, improving N usage has been a major issue in the field of plant science to achieve sustainable production of crops. For that reason, many efforts have been made to elucidate how plants regulate N uptake and utilization according to their surrounding habitat over the last 30 years. Here, we provide recent advances focusing on regulation of N uptake, allocation of N by N transporting system, and signaling pathway controlling N responses in plants.

Reviewing the trend of land use in urban cultivated land, the large part of land has been changed into the high-profit cultivated land of green houses or the developing areas. So, its percent of cultivated land in land use comparing to the other types of cultivated land would get far higher. Therefore, this study aims to identify the characteristics of landscape ecological pattern in the cultivated land of green houses and to find its alternatives for management, which would be a basis of regional planning and management in terms of space and time. The cultivated land of green houses, whose its area reaches 19.3ha, in Seoul are mainly dispersed on the south eastern part of Seoul and its area is larger than the other types of cultivated lands. According to the result of shape index analysis, its perimeters were very simple. Also, Analyzing the first three major neighboring land use to the cultivated land of green houses, the most frequent biotope types of neighboring land use to the cultivated land of green houses were that transportation facility represented 60%, forest, 43%, the other types of cultivated land, 36%, and residential area, 33%. The cause why the percent of transportation facility was higher in the neigh-boring land use types was assumed for the production and distribution of crops. On the basis of the result of landscape ecological pattern analysis, the cultivated land would be managed and contributed to enhance biodiversity and urban environment preservation.

Green manure crops are primarily used to reduce the application of chemical fertilizers. In this study, a two-year field experiment was conducted to evaluate the effects of green manure hairy vetch on rice growth and saving of irrigation water. This experiment was conducted at Sinheung series (fine loamy, mixed, nonacid, mesic family of Fluvaquentic Endoaquepts) from 2008 to 2009 at the National Institute of Crop Science (NICS), RDA, Suwon, Gyeonggi province, Korea. Hairy vetch as a green manure crop was incorporated in soil for rice cultivation. Chemical fertilizers had not been applied to hairy vetch plot. Treatments included once irrigation (OI) per week and conventional irrigation (CI). In 2008, the water use efficiency of OI increased by 46% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 38 days after rice transplanting). In 2009, the water use efficiency of OI increased by 61.3% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 30 days after rice transplanting). Soil physical properties such as bulk density, soil porosity ratio and glomalin contents were improved by the incorporation of hairy vetch. The rice yield of OI water management was not significantly different from those of CI water management by hairy vetch application both years. These results suggest that the OI water management with hairy vetch incorporated in soil for rice cultivation can be used in rice fields to reduce the amount of irrigation water and chemical fertilizer.

Newly introduced two lines of apios (Apios americana Medikus, red-vine and green-vine) were grown in Jeju island, to clarify their growth and production characteristics as well as to develope as a new edible crops in Korea. Both lines bloomed but did not develop to pod and seed. The red-viny line showed the habit of more early growth and maturity compared with green-viny line. Fresh tuber yields per 10a harvested in late November ranged from about 500kg to 800kg as according to the lines and cultural condition. Fresh tuber yield of red-viny line was relatively greater than that of green-viny line, mainly due to their higher tuber number per plant. Among the planting dates(April 1, April 16 and May 1) of seed tubes, highest tuber yield was obtained on May 16 planting. And the stacking cultivation culture was better than non-stacking cultivation in respect of tuber yield and disease avoidance. These results indicate that apios can produce in Jeju island, and in order to extend its cultivation to farmers it will be needed to develope some cultivars with high yields as well as labor-saving cultivation methods.
