10 pages, This study was carried out to reveal the sources of communication and social network of organic and conventional hazelnut producers in Samsun province. The primary and basic material of the study is the data obtained from the surveys, interviews and observations of the organic and conventional hazelnut producers in Çamlıca, Yüksekyayla villages and Ağcagüney town. Both producer groups were compared in terms of their social networks and communication channels especially on the use of different fertilizers by making suggestions on how to develop it. The results of the research showed that socio-economic status of the organic hazelnut producers was better than conventional producers in terms of land size, income, cooperation capacity, risk management and agricultural supports. Social Network Analysis (SNA) has shown the graphs of communication networks among the producers, their relationships with different public, private and mass media information sources and especially revealed leader farmers whom functioned as source of information transfer (or even blocker) among them. The relationships in organic hazelnut producers’ communication network in the village are strong, dense and information sources are varied. On the contrary, the relationships in communication network of conventional hazelnut producers were looser, strong and information sources were uniform. The main source of technical information for both groups of producers was the experienced leader farmers; as for organic producers, the heads of the local organic producers' union was the main information source in terms of commercial, legal and organizational aspects. In other words, both organic and conventional producers rely on knowledge and experience of producers who take on the role of opinion leader within the village. Therefore, innovation and knowledge transfer to farmers can be delivered through these opinion leaders. As a result of the research, it can be said that institutional information sources do not adequately support organic and conventional hazelnut growers. Thus, organic producers developed their local knowledge source based on their on-farm trials and experiences and shared this knowledge within their peer groups. However, this information needs to be supported with scientific findings.
