Farmer Producer Companies (FPCs) have emerged as a transformative institutional model aimed at addressing the challenges faced by small and marginal farmers in India. In the state of Maharashtra, where agriculture is both a crucial economic activity and a livelihood source for a majority of the rural population, FPCs play an increasingly significant role in facilitating collective farming, value addition, and improved market access. This research paper examines the management strategies and sustainable business practices adopted by FPCs in Maharashtra, with the objective of evaluating their effectiveness in fostering long-term viability, profitability, and socio-environmental responsibility. The study employs a mixed-methods approach, combining qualitative case studies of select FPCs across diverse agro-climatic zones in Maharashtra with quantitative data gathered through structured interviews, field surveys, and analysis of secondary data sources. Key areas of investigation include internal governance and leadership models, financial management, stakeholder engagement, capacity-building initiatives, and environmental practices such as resource conservation, climate-resilient agriculture, and organic farming. Findings suggest that the success of FPCs is closely tied to transparent governance, professional management, robust market linkages, and continuous support from governmental and non-governmental institutions. Sustainable business practices are observed to be more prevalent in FPCs that have invested in member education, technology adoption, and decentralized decision-making. However, challenges persist, including limited access to credit, infrastructural bottlenecks, and inadequate managerial capacities among board members. The study concludes that for FPCs to truly become engines of inclusive rural development and sustainable agriculture, there is a need for a multi-stakeholder approach that strengthens institutional frameworks, provides targeted capacity-building programs, and fosters innovation in sustainable agriculture. Policy recommendations include enhancing financial literacy among FPC members, incentivizing sustainable practices, and improving coordination between FPCs, government schemes, and private sector partners. This paper contributes to the growing body of literature on rural agribusiness models by providing insights into the intersection of cooperative management and sustainability, offering a pathway for scalable and resilient agricultural development in Maharashtra and beyond.
