This study evaluate examines the efficiency and the improvement measurement of Oilseed crops (Sesame and Perilla). For this purpose, In the first stage, this study analyzes the current conditions of oilseed industry. In the second stage, this study evaluates the efficiency and super-efficiency of environmentally-friendly agricultural product producers. The result of this study show that: (1) Changes in annual wholesale price of Sesame and Perilla; (2) An efficiency and ranking of environmentally-friendly product producers; (3) The solutions and improvement measurements for inefficient producers

This study examines the management performance of Oilseed crops (Sesame and Perilla). For this purpose, In the first stage, This study analyzes the current status of sesame and perilla industry. In the second stage, This study examines the management performance of environmental friendly agricultural products (Sesame and perilla). The result of this study show that : (1) Changes in annual wholesale price of Sesame and Perilla ; (2) Management performance of environmental friendly products (Sesame and perilla) ; (3) Feature comparison of productivity of oilseed crops.

This study was carried out from 2011 to 2012 in order to analyze the cultivation technology system by six organic rice cultivation types in the southern provinces for the purpose of utilizing organic rice farming guidelines. This surveys were conducted by site visit on 8 counties and 115 farms in southern area. Cultivation technology system by six organic rice cultivation types were cultivated by the principle of minimum input or non-input. cropping systems, a mixture of barley and rice, or rice green manure crops were grown. Cultivars were mixture of the local cultivars and Japanese varieties. Soil were managed by a self-manufactured compost, indigenous microorganisms and barley straw without any fertilization. Pest control was mainly practied by purchased eco-friendly organic materials or herbal medication residue and indigenous microbial self-manufactured. Weed was controled by snails and barley straw. In addition, considering the restore of a longtail pitching shrimp and grasshoppers, the function of environmental ecology of six organic rice cultivation type proved to be excellent all. Meanwhile, the productivity of the organic farming per 10a were the order of Life and environment > Natural circulation > Stevia > Ji jang > Art and nature > Taepyoung of Farming Methods, but the farmers received prices showed the opposite tendency. Simple profitability did not show a big difference. But, the productivity of all type of the organic farming were lower then the conventional farming. Finally, If we want to conduct safety and easy farming, we can suggest stevia farming, Natural circulation farming and life and environmental farming out of 6 organic rice cultivation types.

In this study, of currently being implemented organic cultivation in rice, the economic effects of snail agriculture, natural circulation agriculture, stevia agriculture and art nature agriculture were compared and analyzed. Analysis results showed that the economic effects of selling price per 10a, gross margin and agricultural income were increased, compared to those of previous agricultural techniques. In addition, the comparison results of economic effects by agricultural techniques showed that the agricultural income per 10a of organic cultivation were increased from the national average, compared to that of conventional cultivation. These economic effects analysis by agricultural techniques can help in the decision making of farmers for the adoption of agricultural techniques in the future.
