This experimental study evaluated the potential of Rhizobium inoculation as bio-organic substitute for synthetic nitrogen fertilizer on the growth and yield of peanuts. It also determined the specificity of Rhizobium to peanut varieties and the economics of inoculating peanut compared to synthetic nitrogen fertilization. The experimental area was laid out in split-plot arranged in a randomized complete block design with three replications. The inoculation served as the main plot and variety as the subplot. Rhizobium inoculation significantly increased the height, number of pods per plant, herbage and grain yields of two peanut varieties. It also promoted the development of significantly greater number of effective nodules relative to the N-fertilized and control plants. No significant interactions were observed between inoculation and variety. The UPL-Pn2/Moket variety was relatively superior to the local red variety. The plants grew taller and produced higher herbage and grain yields as compared to the local red variety. Rhizobium inoculation was more profitable than synthetic nitrogen fertilization. Inoculating peanut with Rhizobium species is more beneficial than using synthetic nitrogen fertilizer because it is cheaper and does not pollute the environment
