We have examined the survival of four cowpea rhizobia strains in Jamaican peat to determine its suitability as inoculant carrier. All strains survived well since more than 10 7 cells of rhizobia per gram of peat were recovered from the inoculant after storage for 6 months at 30d̀C. Survival of cowpea rhizobia was better when inoculants were stored at 4d̀ than 30d̀C. The native strains JRC29 and JRW3 (isolated in Jamaica) survived much better than the introduced strains MI‐50A and IRC291 (isolated in West Africa). Survival of cowpea rhizobia was not significantly increased when peat was mixed with 1% sucrose. Our results suggest that Jamaican peat may be used as a carrier for inoculant production.
