The agriculture sector forms the backbone of the Indian economy, yet farmers continue to face challenges in realizing fair prices and sustainable profits due to an unorganized agricultural supply chain. To address these issues, Farmer Producer Organizations (FPOs) have emerged as collective platforms that enhance farmers’ bargaining power and market access. However, the success of these organizations largely depends on the commitment of their members. This study explores the factors influencing farmers’ commitment toward FPOs in Vijayawada, focusing on three key relational constructs: trust, satisfaction, and information sharing. Data were collected from 250 farmers belonging to three FPOs in Vijayawada and the Krishna district. Using Structural Equation Modelling (SEM) with AMOS and SPSS software, the study found that all three variables—trust, satisfaction, and information sharing—have a positive and significant relationship with farmers’ commitment. The model demonstrated a good overall fit. Findings reveal that transparency in payments, participatory decision-making, and regular information flow from NGOs and FPO management significantly enhance farmers’ trust and satisfaction, thereby strengthening their long-term commitment. The results highlight the importance of relational quality in ensuring the sustainability and effective functioning of FPOs in the Indian agricultural context.
