To develop soybean inoculant the effects of inoculation with selected Rhizobium japonicum strains were tested in the field, and the results were as following. With the inoculation of selected strains, increase of nodule number, nodule weight and nitrogen fixing activity were observed with or without applying N-fertilizer. Chlorophyll contents increased and senescence of plant was delayed with the inoculation of selected strains in case without applying N-fertilizer. But there was little difference of chlorophyll contents in case with applying N-fertilizer. There were little differences of plant height and number of nodes, and some increase of plant stem dry matter and number of pods with inoculation of selected strains. The mean yield of inoculation group (363-374kg/10a) increased by 8-11% compared to the uninoculated group (337kg/10a) in case without applying N-fertilizer. The mean yield of inoculated group (368-384kg/10a) increased by 9-14% also in case with applying N-fertilizer
