STRUCTURAL ERGONOMICS AND AGRIBUSINESS PROJECT EFFICIENCY: AN EMPIRICAL ASSESSMENT OF MECHANIZED POST-HARVEST TECHNOLOGY AND OCCUPATIONAL HEALTH INTERVENTIONS IN MANYU DIVISION, SOUTH WEST REGION, CAMEROON

Abstract

This study examined the relationship between mechanized post-harvest technology adoption, occupational health interventions, and agribusiness project efficiency in Manyu Division, Cameroon. A cross-sectional survey design was used with 192 agribusiness enterprises selected through stratified random sampling. Data collected via structured questionnaires were analyzed using Pearson correlation and multiple regression techniques. Results showed a significant positive correlation between mechanized technology adoption and project efficiency (r = 0.675, p < 0.001). Occupational health interventions also significantly predicted efficiency outcomes (β = 0.492, p < 0.001), with the model explaining 61.2% of variance. The study recommends integrating structural ergonomics in machinery design and implementing comprehensive workplace safety programs to enhance processing efficiency and worker protection.
