摘要：The Farmer Field School is a season-long training for farmers involving participatory activities and interactive learning with the doctrine of integrated pest management and agroecosystem analysis. It has become a popular education and extension approach worldwide. This study tried to evaluate the FFS as a vehicle for sustainable agriculture which has economic viability, ecological soundness, and social acceptability. The study aimed to analyze the impact of the FFS on crop income, agroecology, and farmers’ behavior in farming. The empirical models, such as propensity score matching, Mahalanobis distance matching, and difference in differences, were applied for estimating the impact of FFS on crop income, more specifically, real income from brinjal. The environmental impact quotient was used to assess the agroecological impact of using pesticide, and a graded response model was used to investigate farmer behavioral changes in farming. The treatment effect based on the empirical models has shown a positive, significant effect on crop income. The findings also revealed that FFS farmers had a lower agroecological impact from pesticide use, and their behavior in farming practices was improved. Therefore, FFS was demonstrated to be a key strategy in strengthening agricultural extension services, which will contribute to promoting sustainable agriculture.
