Enhancing farmer productivity through participatory approaches and continuous training: A communication quality perspective in North Sumatra’s agricultural sector

Abstract

This study examines the influence of participatory approaches and continuous training on farmers’ productivity, with communication quality as a mediating factor, in four districts of North Sumatra Province. The research investigates how farmers’ active involvement in planning, decision-making, implementation, and evaluation, together with regular and structured training, strengthens their technical and managerial skills. Using a quantitative survey method with primary data collected through questionnaires, the findings show that participatory approaches and continuous training positively affect agricultural productivity. Communication quality plays an important mediating role by ensuring that technical information is clearly communicated and effectively applied by farmers. Clear, open, and two-way communication supports behavioral change and the adoption of innovations in agricultural practices. Overall, the study highlights the need for agricultural development programs to emphasize collaborative participation, needs-based training, and improved communication capacity to enhance farmer productivity and promote regional food security.
