Abstract: Alternative methods of inoculation such as the application of the bacteria Azospirillum brasilense via spray in an advanced stage of the crop can increase the soybean performance. The aim of this study was to evaluate the agronomic traits and grain yield in soybean crops through Azospirillum brasilense doses applied by spray coverage. The experiment was conducted in randomized blocks in a 4 × 6 factorial, with four cultivars (Anta 82 RR® , BRS Favorita RR® , BRS 780 RR® , BRS 820 RR® ) and six doses of Azospirillum brasilense (0, 300, 400, 500, 600, 700 mL ha-1 ) with three replications in two crop years. The characters such as plant height, shoot dry mass, chlorophyll content, leaf nitrogen content at flowering were evaluated. At harvest, the evaluated characters were plant height, height of the first pod insertion, number of pods per plant, number of grains per pod, thousand grain mass, grain yield and grain harvest index. For the conditions that this study was carried out and according to the results, the spray with different Azospirillum brasilense doses did not affect the agronomic variables studied and the grain yield in RR® soybean cultivars.
