In this paper we use plot-level data from semi-arid area of Ethiopia to investigate the impact of organic farming practices on crop productivity, with a particular focus on conservation tillage. Specifically we seek to investigate whether conservation tillage results in more or less productivity gains than chemical fertilizer. Our results reveal a clear superiority of organic farming practices over chemical fertilizers in enhancing crop productivity. Thus our results underscore the importance of encouraging resource-constrained farmers in developing countries to adopt organic farming practices, especially since they enable farmers to reduce production costs, provide environmental benefits, and as our results confirm, enhance crop productivity.engConservation tillageChemical fertilizerCrop productivityMatched observationsEthiopiaText
