The ability of companies to react to changes imposed by the market is related to information acquisition and knowledge generation. Big data technologies, crowdsourcing, and Online Social Network (OSN) are used for knowledge generation. These technologies assumed a significant position in agribusiness. This work investigates how social network analysis can promote agribusiness to provide a basis for future applications and evaluations. We adopted a hybrid systematic mapping to conduct the investigation. Two hundred twenty-three works that propose solutions for agribusiness were found and categorized. Results showed the most used techniques, OSNs, and revealed an increase in the number of studies in this area. The information obtained indicates how social media monitoring can complement traditional methods for decision-making on the management and regulation of agricultural systems. However, agribusiness still lacks more studies using data analysis tools on social networks. Based on our results, we discuss some challenges and research directions.
