Evaluation of Power-Distribution Equipment Systems in Rwanda: A Randomized Field Trial for Yield Improvement Assessment

In Rwanda, power-distribution equipment systems are crucial for post-harvest processing of agricultural products, but their effectiveness varies. A randomized field trial was conducted to assess the impact of different power-distribution equipment configurations on yield improvement in selected agricultural fields across Rwanda. Data collection included pre- and post-trial measurements of crop yields, technological performance metrics, and environmental conditions. The analysis revealed that a specific configuration of power-distribution systems led to an average 15% increase in maize yields compared to conventional methods (confidence interval: 95%, p < 0.01). This randomized field trial provided empirical evidence supporting the effectiveness of certain power-distribution equipment configurations for yield improvement. Based on these findings, recommendations are made for further research and implementation of optimised power-distribution systems in agricultural settings to enhance productivity and sustainability. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
