concepts and practices of scientific beekeeping as indicated by scores in pre-test (vj = 25.92). Further. there was a significant increase in their knowledge level after the intervention (exposure) of participatory Newsletter as their post-test score increased - from Mean Score of 25.92 to 36.97. The average gain in knowledge was 11.053. Further, the results of paired t-test indicate that table that valu was some gain in knowledge in most of the aspects (Statement) of the honey production by the respondents. Further, in order to find out whether this gain in knowledge was significant, paired t-test was done. The results obtained are given in Table 2. Table 3: Opinion of respondents about Newsletter (n=75) Table 2: Paired ‘t’ test for relative effectiveness of participatory Newsletter (n=75) concepts and practices of scientific beekeeping as indicated by scores in pre-test (X7 = 25.92). Further, there was a significant increase in their knowledge level after the intervention (exposure) of participatory Newsletter as their post-test score increased - from Mean Score of 25.92 to 36.97. The average gain in knowledge was 11.053. Further, the results of paired t-test indicate that table that value of ‘t’ cal is higher than value of ‘t’ tab at 1% level of significance. It means that the post-test scores of the respondents were significantly higher that their pre- est. Thus, it can be inferred that the knowledge gain due to exposure to the participatory Newsletter among the respondents was found to be significant. Hence, it can be concluded that the intervention of Participatory Newsletter made a significant difference to the knowledge of respondents. The findings are similar to Ekoja (2003) study on farmer’s access to agricultural information in Nigeria and Chung (2008) who conducted a study on interactive feature of online newspaper. of ‘t’ cal is higher than value of ‘t’ tab at 1% level of significance.
