Abstract
Field research stations in Ghana are crucial for understanding and improving agricultural productivity, particularly in relation to energy efficiency and yield improvements. Bayesian hierarchical models are employed to analyse data from various field research stations across Ghana, integrating both quantitative and qualitative datasets for comprehensive evaluation. A key finding is the significant improvement in crop yields of up to 15% observed when implementing optimised energy management practices within the study area. The Bayesian hierarchical model effectively captured spatial variability in yield improvements across different stations, providing robust insights into optimal resource allocation strategies for farmers. Based on findings, recommendations include prioritising research stations with higher potential for yield improvement and disseminating best practices to enhance agricultural productivity sustainably.
