Effect of pectin amendment as a 1% (w/v) liquid suspension on soybean yield by B. velezensis PGPR strains AP136, AP193 and commercial B. japonicum inoculant in the field trial. The mean value in the column followed by the same letter are not significantly different at p ≤ 0.05 using Duncan’s multiple range tests. * Plot weights indicated the total pounds harvested from the two center rows of the four-row plot. ** Test weights indicated the number of pounds in one bushel of soybeans.
