Field research stations play a crucial role in agricultural development in Senegal by providing controlled environments for testing new crop varieties and farming practices. Multilevel regression models were employed to analyse data from multiple levels (e. g. , individual farmers, villages, regions) collected through surveys and experimental trials. The models account for both fixed effects (station-specific conditions) and random effects (variability between stations). The multilevel regression analysis revealed significant station-level differences in the adoption rates of improved crop varieties, with some sites showing a 25% higher rate compared to others. This study provides robust evidence on the impact of research station environments on agricultural practices and outcomes, highlighting areas for improvement in station operations. Based on these findings, recommendations are made for optimising resource allocation within Senegalese field research stations to enhance their effectiveness in promoting agricultural innovation.
