This study builds upon previous research in Rwanda to evaluate the effectiveness of process-control systems designed for improving agricultural yield. A quasi-experimental design was employed, including pre- and post-intervention data collection from randomly selected agricultural fields. Process-control systems were implemented in one group of fields while conventional farming methods served as the control. The analysis revealed a statistically significant $Y = 100 + 5X$ increase in yield for the treated fields (95% CI: [85, 115]) compared to the control group. The replication study confirms and extends previous findings on the efficacy of process-control systems in enhancing agricultural productivity in Rwanda. Future research should consider broader implementation strategies and assess long-term sustainability impacts of these systems. quasi-experimental design, yield improvement, process control, agricultural productivity, Rwanda
