Intercropping is the instantaneous cultivation of two or more crops in both space and time. The demonstration was carried out during the main rainy season of 2019/20 in the Adola Rede and Odo Shakiso districts of Guji Zone, Oromia, Ethiopia with the objectives of evaluating yield performance and cost-benefit ratio of maize-haricot bean intercropping practices under farmers’ condition and assessing farmers’ and others stakeholders’ preference on maize-haricot bean intercropping practices. Based on their potential for producing haricot beans and maize, two Kebeles per district were selected and 15 farmers from each Kebele were selected to form one FRG. As a result, 4 FRGs, a total of 60 farmers-45 men and 15 women-were formed. The study demonstrated improved maize (BH-546) and haricot bean (Haramaya) varieties through their sole cropping on 100 m2 plots, with their recommended seed and fertilizer rates, and enhanced farmer-to-farmer learning through training, exchange visits, and field days. The data was collected using observation, measurement, face-to-face interviews, and intercropping metrics. The collected data was analyzed using descriptive statistics, and farmers' preferences were analyzed qualitatively. The demonstration results showed that 2.75 tons of maize and 2.32 tons of haricot beans per hectare were yielded, with a net return of 28,007.67 ETB/ha. Based on grain production per hectare, economic gain, and intercropping metrics, maize-haricot bean intercropping proved crucial for small-scale farmers in areas of land scarcity and moisture stress, such as the midland of Guji and similar agroecologies.
