The purpose of this study is to examine the management performance and to evaluate efficiency of Yacon’s farmers. So, This study analyzes the productivity of Yacon by certification types in Korea. and, this study examines the management performance and efficiency of environmental-friendly agricultural products. First, Looking at the management performance by cultivation type, Revenue, Organic is 4,326,198 won, Non-pesticides is 3,812,660 won, Normal is 3,025,767 won. and Income, Organic is 2,193,831 won, Non-pesticides is 2,001,907 won, Normal is 1,779,026 won. Second, The technical efficiency, pure technical efficiency, and scale efficiency measure of Yacon by certification types. Organic is 0.967, 0.988, 0.979 and Non-pesticides is 0.940, 0.994, 0.994. and the results of bootstrap DEA, Organic is 0.923(TE), 0.949(PTE), 0.972(SE) and Non-pesticides is 0.898(TE), 0.979(PTE), 0.917(SE). Third, as a results of DEA by bootstrap model, all were found to be in the range of 95% confidence intervals. Forth, when analyzed using a general DEA model, the problem of discrimination has occurred. but, Result of using bootstrap DEA, it was possible to see the exact ranking is corrected excessively estimated bias. and using Mann-Whitney assay, it was found that a statistically significant difference exists. Finally, Organic has been found that there is a need to improve the inefficiencies of PTE. Non-pesticides has been found that there is a need to improve the efficiency of the SE.
