Evaluation of Effective Rhizobium Strain on Nodulation, Yield and Yield Attributes of Faba Bean in Case of Chancha Woreda Southern Ethiopia

Abstract

Nitrogen is an important element for plant growth and its availability in sufficient amount boosts production per unit area, increases the total supply of food and contributes to the quality of food. However, resource poor farmers in the tropics especially in Ethiopia are not able to use enough amount of inorganic N fertilizer for crop production due to high cost, and hence looking for alternative means of improving available nitrogen in the soil is crucial. Therefore, this study was conducted to indentify the best Rhizobium strain for faba bean production in chancha woreda and to determine the yield and yield attributes of the faba bean with the application of Rhizobium strains. The ANOVA revealed that the significance difference between the inculcation of different rhizobium spices for faba bean production in chancha woreda. The highest mean in all parameters of the faba bean was recorded from the inculcation of strain 1035 with the combination 50kg DAP/ha. The finding of this research will be repeated in same agro ecological areas before farmer’s dissemination Keywords: Biological nitrogen fixation, Faba bean, Rhizobium
