The objectives of these studies were to evaluate the effects of soil moisture content on nodulation, nitrogen fixation, growth and yield of soybean S.J.2 inoculated with Rhizobium japonicum. Two sets of experiments were conducted, the first was designed to evaluate nodulating of soybean and the second fixation and yield observations. These were performed by mixing the seeds with Rhizobium japonicum powder using gum arabic as adhesive material and the inoculated seeds were planted in pots containing fertilized and limed Korat soil moisture was kept at 100 percent FC for 10 days after planting, then adjusted to 100, 80, 60 and 40 percent FC following with water addition at 1,2,3,4 and 5 days intervals. Results revealed that nodulation in soils with high moisture contents plant growth and nitrogen fixation were relatively higher than those of soils with lower water contents. Addition of water at one day intervals gave better growth, higher nitrogen fixation, and higher seed yield than those of the other treatments. It was suggested that to obtain good nodulation, nitrogen fixation, growth, and yield of soybean grown in Korat soil, soil moisture contents be kept between 80 to 100 percent FC and water be added at 1 to 2 days intervals
