Data analysis included validity and reliability tests, classical assumption tests, and multiple linear regression using SPSS software to assess the influence of various independent variables. Main Findings: The study found that farmers' interest in using Trichoderma sp. was generally high. Among the factors examined, the role of extension workers and the availability of facilities and infrastructure had a significant positive effect on farmers' interest. In contrast, age, education level, and farming experience did not have a significant influence on their interest in adopting Trichoderma sp.. Novelty/Originality of this study: This study uniquely explores the socio-demographic and institutional factors influencing farmers’ interest in adopting Trichoderma sp., which has rarely been addressed in previous research.
