The purpose of this paper is to examine introduction effects of certification standards of cultivation and management of agricultural production proceses by means of a case study of a Broccoli-producing district in Hokkaido. The main findings are as follows. 1)Production costs per area under the certification standards were higher, because of increases in work time and material costs such as weeding,crop maintenance, learning, and record keping. However, production costs per head did not increase, as yields under the certification standards were higher than the ordinarily grown product. 2)The price received by farmers under certification standards was higher than the ordinarily grown. Further, there were also price increases in the ordinarily grown. 3)Higher evaluation from the market was achieved through optimum use of fertilizer and chemicals with the standards of the specially cultivated agricultural products, and so achieving the response to customer demands with standard of GLOBAL G.A.P.
