This study investigates the application of process-control systems in improving agricultural yields in Kenya, focusing on methodologies for multilevel regression analysis. A multilevel regression analysis was employed, considering multiple levels of data including farm-level inputs, farmer characteristics, and environmental conditions. The study utilised a mixed-effects model to account for both fixed and random effects in the dataset, ensuring robust estimates across different scales. The analysis revealed that incorporating process-control systems at the field level significantly improved yields by an average of 15% compared to traditional farming methods (95% confidence interval: 13-17%). This study supports the adoption of advanced process-control systems for enhancing agricultural productivity in Kenya, particularly at the farm-level. Farmers and policy makers are encouraged to invest in and implement these systems as a means to achieve sustainable yield improvements and boost overall food security.
