Abstract

The study was conducted in two districts of coastal areas of Bangladesh for assessing the performance of research extension linkage towards adoption of salt tolerant rice varieties. Four villages from both Shaymnagar upazila under Satkhira district and Paikgachha upazila under Khulna district were purposively selected as the study locations. The target population of the study consisted of researchers, extension personnel and farmers who are involved in technology development, dissemination and utilization of salt tolerant rice varieties. Three organizations viz. Bangladesh Rice Research Institute (BRRI), Bangladesh Institute of Nuclear Agriculture (BINA) and Department of Agricultural Extension (DAE) were selected purposively for the study. A total of 97 researchers and DAE personnel were purposively selected as population. Out of them; 40 researchers (20 from each organization) and 20 DAE personnel (about 60 percent) were selected as sample. On the other hand, total population of 1,255 farmers (250 strong linkage farmers and 1005 weak linkage farmers) from both the upazila were also selected purposively. Out of them, 200 farmers (100 having strong linkage and 100 with weak linkage) were randomly selected as sample for the study. The linkage performance was measured in three dimensions like, planning performance, management and implementation performance, monitoring and evaluation performance. The results indicated that regarding planning performance, the researchers and DAE personnel had strong linkage performance which was 92.5 percent and 80 percent respectively. In measurement of management and implementation performance, and monitoring and evaluation performance, the respondents had strong linkages which were 90 percent and 80 percent, and 90 percent and 75 percent, respectively. However, the relationships between the selected characteristics of the researchers and DAE personnel, five variables were found significant such as the authority activities, contact with information media, linkage activity, financial support and team work. While, in case of individual contribution of linkage performance, linkage activity showed the highest contribution (18.8 percent), team work showed 16.4 percent and job satisfaction showed only 4.1 percent in explaining variation in linkage performance. In case of strong linkage farmers, the highest number (60 percent) of the respondents had high adoption of salt tolerant rice varieties, while one third (33 percent) had medium and 7 percent had low adoption of salt tolerant rice varieties. However, in case of weak linkage farmers, less than half (45 percent) of the respondents had high adoption of salt tolerant rice varieties, while 33 percent had medium and 22 percent had low adoption of salt tolerant rice varieties. Based on the findings, it may be concluded that overall research extension linkage performance was strong which influenced the adoption of salt tolerant rice varieties among the strong linkage farmers. Thus, it is recommended to enhance linkage performance among the strong and weak linkage farmers that might contribute to enhance the extent of adoption of salt tolerant rice varieties in coastal areas of Bangladesh.
