Knowledge networks and social networks are the drivers of information sharing and they play an important role in diffusion of technology and related knowledge. In this study the key informants in a village setup are studies to understand the farmer’s network with an objective to understand the existing social, knowledge systems and their structure, characteristics and relationships between different actors. The purpose is to use these channels as means to disseminate technologies and related information. We use the network map analysis as a tool to demonstrate the linkages between the key actors. Attributes captured in the study are information flows between different actors, the type of information, timeliness and frequency of information and mode of communication. The study is undertaken in 6 districts covering 20 villages of Bihar where 111 key informants were interviewed and this is supplemented with survey of 1000 households. The paper uses a mixed approach of quantitative and qualitative analysis.
