Legumes yield response to Rhizobium inoculation in Ethiopia: A review

Ethiopia has been known as the homeland and domestication centre of several crop plants. Area unsuitability, un-productiveness, diseases, and insect pests are the most legume crop yield-limiting factors. However, leguminous plants have capacity for nitrogen-fixing symbiosis when established with gram-negative Rhizobia and then, incorporates atmospheric nitrogen to soil. Commercially many different species of Rhizobium have been prepared. To improve soil fertility, inoculating with Rhizobium before planting leads to substantial yield increase. There are a number of Rhizobium inoculation experiments for different legumes in Ethiopia. Conversely, they are not organized, to access easily. Therefore this review was undertaken to assemble yield response of legumes to Rhizobium inoculants in Ethiopia. Yield response of common bean, soya bean, chickpea, faba bean and lentils to Rhizobium inoculation were collected and summarized.
