Economic valuation of microbial genetic resources was conducted in three Zones, Arsi from Oromia, East Shoa from Amhara and Wolhyta from Southern Nations Nationalities and People’s Region (SNNPR) of Ethiopia. Willingness to pay (WTP) bids to use Rhizobia bio-fertilizer for production of different legumes was calculated. The average willingness to pay for bio-fertilizer in haricot bean production was 201.76 USD (at existing exchange rate) /household/ year. When bio-fertilizer was used for faba bean production, increase by 1 hectare of land, increased the willingness to pay for bio-fertilizer by 667 USD/quintal/year. Moreover, Higher income is significantly related to higher WTP at (F=72.17, sig. = 0.000). In general the study showed that those farmers who have gained benefits from using Rhizobia biofertilizers in all the studied Sub-districts (kebels) indicated highest WTP for the bio-fertilizers in the study. There were certain factors like size of land holding, yield per hectare and herbicides that affected the total yield and thereby the WTP. Although there might be other factors that contributed for yield increases of the leguminous plants in the studied area, it may be possible to conclude that the benefit from the use of the bio-fertilizer was significantly higher compared to those gains obtained without using bio-fertilizers. Despite that there has been certain controversy on methodological issues involving willingness-to-pay, the support of WTP in determining the economic value of genetic resources widely increased. Thus the current economic value estimate of the rhizobia bacteria may be indicated by the WTP of the studied farmers.
