Description A successfulRhizobium inoculant strain needs to be more competitive than native soil rhizobia in forming nodules and to be effective in fixing nitrogen. Persistence of the strain from one season to the next will be an added advantage, since it eliminates the need to inoculate every season. Earlier studies indicated that groundnut,Arachis hypogaea, seldom responds toRhizobium inoculation in soils already containing rhizobia which nodulate groundnut. However, the results of seven years of research at ICRISAT have opened up the prospect of inoculating groundnut in such soils. These experiments indicate that inoculating with sufficient numbers of an effectiveRhizobium strain, NC 92, applied as a liquid slurry below the seed, increased yields of certain groundnut cultivars. Similar results were reported from other research centres in India. Inoculation with NC 92 for two consecutive seasons increased the proportion of nodules formed by this strain, from 25–32% in the first season to 41–54% in the second season, indicating that this strain can persist in the field for the following season. This paper also discusses results of experiments relating to host cultivar specificity and some possible problems in applying this information to farmers' fields. Strain NC 92 also produces a siderophore, an iron chelating compound, which may help in the iron nutrition of the plant
