Sorghum and Soybean are staple food and feed crops in Ethiopia. One of the strategies that boosts production and productivity of both commodities is intensification. Field experiments were done in 2018 and 2019 at eastern Ethiopia to determine the effect of intercropping sorghum with soybean on grain yield. Seed yields were higher in the sole crops of sorghum and soybean than in the individual components of the intercrops. This is due to the crops' competition for nutrients, light, water, and other factors. The yields of the intercrop's component crops varied greatly depending on the variety. The sorghum/soybean (Teshale/Awasa-95) intercrops were more productive than the sorghum/soybean (Dhaqaba/Awasa-95) intercrops, which had a land equivalent ratio (LER) of 1.14. Intercropping sorghum (Teshale) with soybean (Awasa-95) resulted in maximum grain production and LER greater than one, showing that intercropping has an advantage over solely planting. As a result, intercropping sorghum and soybean is compatible, desirable, and more advantageous for increasing production than solely cropping under the same conditions. Farmers of the region and similar agro-ecologies are advised to use sorghum/soybean intercropping practice to increase production per unit area.
