Demonstration and Promotion of Biofertilizer Application for Maximum Grain Yield of Faba Bean(Vicia faba L.) Variety: The Case of Alicho Wuriro District

Abstract

This experiment was conducted at Alicho wuriro district of SNNPRS during the 2015 cropping season with the objectives to demonstrate and popularize rhizobia strains used as bio fertilizer to enhance the productivity of faba bean. A total of thirty farmerswere randomly selected and organized to participate in the treatments evaluation. Single plot with 10 m x 10 m size was used. Nodule number per plant had positive and significant (p<0.05) correlation with grain yield and pod per plant.Treatment FB-1035 rhizobium inoculation+ Dosha + 121 kg NPS /ha gave the highest grain yield (2.68 t ha^-1) and had yield advantage of 78.67% over control and got higher score in all parameters and selected as 1^st by farmers at study area. Therefore, itwas recommended for production at Alicho wuriro district and similar agro ecological conditions to improve faba bean production and productivity under smallholder farmers.
