Abstract

The objective of this work was to verify the potential use of comercial biological products in coinoculation with Bradyrhizobium japonicum in the treatment of soybean seed. Seven treatments were carried out with five repetitions, being: T1 – Control, T2 – Only Bradyrhizobium japonicum, T3 – B. japonicum + Azospirillum brasilense, T4 – B. japonicum + Bacillus subtilis, T5 – B. japonicum + Bacillus amyloliquefaciens, T6 – B. japonicum + Bacillus methylotrophicus e T7 – B. japonicum + Bacillus pumilus. The analyzed variables were germination (G),

germination of normal seedlings (GN), emergence speed index (IVE), and, at the end of eight days, aerial part growth in pot (CAV) and germitest paper (CAG), potted root (CRV) and germitest paper (CRG). The data were subjected to analysis of the assumptions and determined from the Tukey test at 5% probability and the principal component analysis (ACP). It was possible to observe that the coinoculation of B. japonicum + A. brasilense promoted rooting and germination gains in soybean seedlings. Coinoculation with B. pumilus showed an effect potential similar to the association of B. japonicum + A. brasilense. The association with B. methylotrophicus showed better rooting in pot (CRV) than the other treatments. The use of BPCP"™s in association with B. japonicum enhances the initial development of the plant.
