Methodological Evaluation of Smallholder Farms Systems in Ethiopia: Randomized Field Trial for Measuring Cost-Effectiveness

Smallholder farms in Ethiopia face challenges related to cost-effectiveness when adopting new agricultural practices. A randomized field trial was conducted among smallholder farmers in selected regions of Ethiopia. Data collection included economic inputs (costs) and outputs (yield), with statistical analysis using linear regression models to assess the relationship between input costs and yield outcomes. In a specific region, an average increase of 10% in crop yields was observed when implementing cost-effective agricultural practices compared to traditional methods. The randomized field trial validated the effectiveness of cost-effectiveness measures for smallholder farms, providing insights into optimising resource allocation and increasing productivity sustainably. Farmers should be encouraged to adopt the recommended practices based on the findings from this study, with particular focus on regions where yield improvements were most significant.
