A field experiment was
conducted during the July to November 2012 growing season at Kyushu University
Farm, Japan, using a split-plot design with three replications and the
following four treatments: T1, an uninoculated treatment with peat moss
(uninoculated); T2, a single inoculation with </span><i><span style=\"font-family:Verdana;\">S.</span></i> <i><span style=\"font-family:Verdana;\">griseoflavus</span></i><span style=\"font-family:Verdana;\"> P4 (P4); T3, a single inoculation of </span><i><span style=\"font-family:Verdana;\">B. yuanmin</span></i></span><i><span lang=\"EN-US\" style=\"font-family:Verdana;\">gense</span></i><span lang=\"EN-US\" style=\"font-family:Verdana;\"> MAS34 (MAS34); and T4, a dual inoculation of P4 with MAS34 (P4 + MAS34).

The N</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> fixation activity of soybean was evaluated by the relative ureide method using
xylem solute from root bled sap at the early pod-fill stage (R3.5). Dry matter
production, N</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> fixation, and seed yield were significantly (</span><i><span style=\"font-family:Verdana;\">P</span></i></span><i><span lang=\"EN-US\"> </span></i><span lang=\"EN-US\" style=\"font-family:Verdana;\">&lt;</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">0.01) different between the inoculated treatments.
