A granular inoculant using volcanic cinder was developed and evaluated in pot and field trials using soybean. The granular material listed maintained a population of 10 to the eight power rhizobial cells/g up to 7 months of incubation even at room temperature. In the pot experiment, granular inoculation markedly improved nitrogenase activity and N uptake of soybean over seed inoculation. However, dry matter yield and grain yield due to granular inoculation were not significantly different from seed inoculation. Nodule occupancy by the inoculum strains was significantly higher with granular inoculation. In the field where soybean was planted after lowland rice, granular inoculation using three different strains markedly improved nodule number and dry weight over seed inoculation. Dry matter yields of soybean due to both methods of inoculation were comparable. Grain yield of soybean was consistently higher with granular inoculation than with seed inoculation but differences were not significant.
