Field research stations in Tanzania are crucial for agricultural development, yet their effectiveness varies significantly. A multilevel regression model was employed to analyse data collected from multiple stations over a period of two years. The model accounts for both station-level and site-level variability in the reported agricultural productivity outcomes. The multilevel regression analysis revealed that station-level factors significantly influenced crop yields, with an estimated coefficient of 0. 53 (95% CI: 0. 41, 0. 65), suggesting a moderate positive effect on yield per hectare. This study highlights the importance of considering both station and site-specific variables to accurately measure agricultural productivity outcomes. Future research should focus on improving communication channels between stations and local farmers to enhance adoption of recommended practices. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
