摘要

Green Thumb (GT) was a test of an information retrieval system that was designed to provide farmers with weather and other agricultural production and market information in a timely and convenient manner. Video-text users were linked to the GT computer at the University of Kentucky via county Cooperative Extension computers, telephone lines and home TV sets. The 200 farm families in the GT experiment used key pad home computer terminals to retrieve selectively specific frames of information they wished to view. The experiment was conducted from March 1980 to July 1981. The evaluation focuses on organizational and technical performance of the GT project, and on analyses of computer records of user retrievals of GT information. The genesis and development of the GT system in Kentucky is described, including costs and specifications of equipment. Findings include rates of retrieval of information from GT; informational topics most frequently accessed, and; relation of farmers' characteristics to frequency and type of informational retrieval. The authors recommend that Cooperative Extension should further develop and implement GT-type videotext systems. The report also provides specific suggestions for videotext computer hardware, software and information content as well as the role of extension specialists in future agricultural videotext systems.
