Abstract Background Rwanda and most parts of sub-Saharan Africa face severe challenges of increasing maize productivity, which has direct consequences on food security. Due to these challenges, policy-makers have paid particular attention to finding the cost-effective strategies of boosting maize production. In an effort to increase productivity, the literature suggests that the adoption of yield-enhancing technologies and production efficiency should be given priority. The objective of this study is to examine and compare the technical efficiency and technological gaps of maize farms that grow different seed varieties in Rwanda. Methods The data used in this study were obtained from a survey of 360 household farmers conducted in the Eastern Province of Rwanda during the 2018–2019 cropping season. The study applies the stochastic meta-frontier production function approach to estimate the technical efficiency and technological gaps of maize farms operating under heterogeneous production technologies. Results Results indicate that there are differences in technical efficiency measures among the three groups of farmers (i.e., adopters of hybrids, open-pollinated varieties, and local maize varieties). In particular, we find that on average, farms growing hybrid maize varieties appear to have higher values of technical efficiency, technology gap ratio, and meta-frontier technical efficiency than farms growing OPVs and local maize varieties. Thus, the analysis shows that there are significant technological and managerial performance gaps among farmers. Conclusions From a policy perspective, the results of this study suggest the development of policy measures that may reduce the managerial and technological gaps existing among farmers to improve productivity and food security. Based on the results of this study, one of the crucial avenues to close this gap would be to improve access to improved agricultural technologies such as certified hybrid seeds. Additionally, policies aiming to enhance technical efficiency and productivity should focus on expanding the delivery of extension services and strengthening the technical assistance provided to farmers’ cooperatives.
