Abstract

Regional scientific journals play a crucial role in the dissemination of locally relevant knowledge and the strengthening of research networks. For three decades, Pesquisa Agropecuária Gaúcha (PAG) has served as a central vehicle for publishing applied agricultural research in southern Brazil. This study investigates the co-authorship patterns and institutional affiliations of the most productive authors in PAG over its 30-year publication history. Drawing on scientometric indicators and Social Network Analysis (SNA), the research identifies the top 40 authors ranked by productivity, degree centrality, betweenness centrality, and PageRank. The results reveal that public research institutions, particularly SEAPI-RS, Fepagro, and Embrapa, play a dominant role in the journal’s scientific output, with federal universities such as UFRGS also contributing significantly. Community detection reveals cohesive clusters, most notably those centered on SEAPI-RS and UFRGS, which reflect the structured and sustained nature of regional scientific collaboration. The analysis underscores PAG's role as a strategic platform for disseminating applied agricultural research in southern Brazil and demonstrates the value of network-based approaches for characterizing the dynamics of scientific collaboration in specialized journals.
