It can be said that many desirable training programs should be evaluated over a long period of time. This is more true when the training is concerned with the adoption of certain agricultural technologies and production innovations. Nevertheless, most of the evaluation studies of the farmers training programs have been carried on during or immediately after the training sessions. In view of such consideration, the present study was conducted with the following two objectives: 1) To investigate any differences and relationships between the perception and adoption of recommended rice production practices among three different groups divided according the degree of participation in the Winter Farmer Education, and 2) To explore any differences and or relationships between technical adoption and agricultural productivity among different groups. For this study a winter farmer education was undertaken in the pilot village of Rural Development Laboratory, College of Agriculture, Seoul National University, from December 1973 to February 1974. After completion of the in-door education, researchers visited two or three times a month and collected follow-up data through observation. And personal interview with the farmers was made in January 1975. Forty-nine households of 63 households at the pilot village were interviewed. According to the degree of participation in the farmer education, the households were devided into three groups: full-participants group(17 households), partial-participants group(14 households), and nonparticipants group(18 households). Three independent variables were the perceived value of the innovations in terms of relative advantage, complexity and observability. The intervening and dependent variables were technical adoption and agricultural productivity respectively. Data were analyzed by using mean, percentile, Chi-square, t and F test. And simple correlation and multiple correlation methods were employed. The level of significance was five percent. As a result, the following major facts were found: 1) The three groups had significant differences in perception of recommended rice farming innovations in general. In other word, the more the farmers participated in the farmer education, the more they perceived of the new farming techniques. 2) There were differences among three groups in adoption of recommended rice farming techniques and their willingness to adopt these techniques in the following year, at .01 level of significance. It reveals that the Winter Farmer Education had the considerable positive effect on adoption of new farming technologies. 3) Although the degree of farmers' practical adoption of recommended techniques was low in general within one year after the farmer education, the technical changes were positively related to the degree of participation in the Winter Farmer Education. 4) There was positive relationship between three perceived attributes of rice farming innovation and the practical adoption of these techniques(R=.762). The correlation coefficient between each attiributes (relative advantage, complexity, and observability) and adoption of recommended rice farming techniques were 0.692, 0.627, and 0.710, respectively. 5) The degree of participation in the farmer education was not related significantly to the increased rice yield in 1974 over the year of 1973. However, in the case of full and non-participants groups the yields were increased beyond .01 level of significance. The rates of increase in rice productivity of the full, partial and non-participants groups were 23, 9 and 17 percent, respectively. Such a result showed the possibility that the farmer education might have some influence on the increase of agricultural productivity.
