The study was conducted in Wardha district of Maharashtra State where front line demonstrations on seed treatment in soybean were conducted by KVK on farmers field. Total fifty FLDs were evaluated to access their impact on adoption and relative advantage, compatibility, complexity and observability. It was found that seed treatment in soybean gives 56.93 per cent more yield as compare to untreated seed. Almost all the respondents expressed that seed treatment requires no labour and majority said that initial cost was also very low. In the compatibility issues cent per cent farmers reported that this technology is suitable to agro-climatic conditions, consistent with existing situation and compatible with norms of culture. Over 90.00 per cent respondents accepted that it meets felt need of farmers. All farmers stated that seed treatment is easy to understand and perform. Effect of technology was found visible to 100.00 per cent farmers. In the categorization, majority of respondents were found to be taken high relative advantage, highly compatible, low complexity and high observability. In total, technology effectiveness calculated was 91.96. Regarding impact on adoption, most of the respondents (68.00%) were accepted the technology but not able to adopt due to some constraints. Farmers have given feedback that with the low cost inputs, technology was very effective to increase the yield of soybean (100.00%), bio-products are not readily available in local area (100.00%), darken the hands and cloths and burning the eyes are the complaints of farmers using bio-treatment of the seed. In the relational analysis, relative advantage and observability were positive and highly significant with the adoption of seed treatment whereas, complexity was highly but negatively correlated with the adoption.
