This study analyzed Bolivian farmers’ perceptions of and the effectiveness of the KOPIA agricultural support program. A survey of 171 respondents assessed their experiences with program participation, the types of support received, perceived changes, preferred forms of assistance, participation modalities, and their trust in KOPIA’s technical support. The majority of respondents evaluated the program positively, specifically highlighting improvements in crop productivity and income, the acquisition of new agricultural technologies, and access to high-quality seeds and inputs. Farmers’ high level of trust in KOPIA stemmed from the provision of quality resources, the practical utility of introduced technologies, the professionalism and accountability of technical staff, the availability of training and educational opportunities, and consistent, transparent project management. The findings indicate that KOPIA’s field-oriented technology transfer and continuous support enhance farmers’ productivity, self-reliance, and trust, thereby significantly impacting local agricultural development.
