Social Networks like Facebook, Twitter, YouTube and WhatsApp are now becoming very popular tools that are used for sharing the latest and important farming based information in different part of India. These tools are now widely used by Agricultural Extension and Advisory services to interact with the farmers for exchanging agricultural related information in India. The most influential farmers in a network can disseminate the information to the less central farmers of the network. The extension functionaries that promote the agricultural innovation will share the information with the most central members which in turn will share it with maximum number of the members of a social network. Social Network Analysis (SNA) acts as an efficient analytical tool that helps us to understand the relationship between farmer stakeholders and the importance of a farmer's position in the entire network. In this paper, a structural analysis of the Social Network is performed over two datasets, namely, Facebook-like dataset and Twitter Lists dataset. Here, we have studied the importance of individual nodes in the network through various centrality measures. SNA properties like centralities are used to represent the most central nodes that can act as a good influence spreader in the network. In this paper, initially the k-core decomposition method is used to find a set of influential nodes among all the nodes in the network. It is done to reduce the computational time. Our simulation shows that the nodes with higher Page Rank centrality can activate more members in a network as compared to other centrality measures. For Information diffusion, we have used Linear Threshold (LT) Model to understand the influence spread of the central farmers in the network.

Also in
27 pages, Extension programs must constantly evaluate communication plans and platforms to determine if they are worth the investment of time, money, and resources. Podcasts are growing in popularity as a communication platform for education and entertainment. With the VARK model of learning styles and core plant pathology concepts as a guide, researchers evaluated the prevalence and type of plant pathology information in podcasts to better understand how podcasts could benefit Extension plant pathology programs. Using keywords related to plant pathology, researchers searched popular mobile podcast listening applications and evaluated relevant podcast episodes using content analysis methods. Results indicated few podcast shows discuss plant pathology topics. The podcast shows identified, however, covered eight fundamental units of plant pathology knowledge: basics of plant pathology, plant pathology techniques, biology of plant diseases, biology of plant pathogens, management of plant diseases, influence of the environment, other causes of plant disease symptoms, and importance of fungi. Results suggested that podcasts can effectively communicate different types of plant pathology information to audiences. Plant pathology Extension programs can utilize the findings of this study to create new plant pathology podcasts that meet the changing needs of plant pathology Extension clientele. It is worthwhile to further explore the use of podcasts in plant pathology Extension programs.
