The Use of Acid Tolerant Soybean and Acid-Al Tolerant Nitrogen-Fixing Bacteria Was an Alternative Way to Increase Soybean Productivity on Acid Soils. This Research Was Conducted to Study the Influence of Acid-Al Tolerant <em>Bradyrhizobium<span>  </span>japonicum </em><span> </span>on Growth of Slamet Cultivar Soybean Planted on Acid Soils in Greenhouse. Three Strains of Acid-Al Tolerant <em>B. japonicum</em>, i.e. BJ 11 (19), BJ 11 (5), and BJ 11 (wt), Were Used in This Experiment. The Result Showed That Inoculation of All Acid-Al Tolerant <em>B. japonicum</em> Strains Could Increase Plant Height, Shoot and Root Weight, Number of Flowers, Pods, Seeds, Seeds Dry Weight, and Shoot and Seed Nitrogen content.</span></strong></p> <p class="MsoBodyText2" style="line-height:10.8pt;"><strong><span style="font-size:9pt;"> </span></strong></p> <strong><span style="font-size:9pt;"><span>                </span></span></strong><span style="font-size:9pt;">Key Words: <em>Bradyhizobium Japonicum, </em>acid-Aluminium Tolerant, Soybean, Slamet cultivar</Span&gt;”.
