Quasi-experimental designs have been widely used to evaluate yield improvement in smallholder farm systems in Senegal, particularly focusing on interventions such as improved seeds and agricultural practices. The methodology involves a comprehensive search of peer-reviewed journals, conference proceedings, and grey literature published between and. The review employs quantitative synthesis techniques to analyse the methodological rigor of quasi-experimental designs used in these studies. Analysis revealed that while many studies employed quasi-experimental designs effectively, there was a notable lack of consistent application of randomization procedures across different study sites. The review concludes with recommendations for enhancing the robustness and comparability of future quasi-experimental designs in smallholder farm systems within Senegal. It is recommended that researchers adopt standard operational procedures, including proper randomization, to ensure more reliable yield improvement assessments. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
