The objective of this study was to evaluate the effect of inoculation of Bacillus subtilis and\udAzospirillum brasilense on growth and yield of corn. The experiment was conducted in the\udmunicipality of São Jorge Ivaí during the period April to August 2013 in outlined in a randomized\udblock design with five treatments and four replications. T1 - Control; T2 - Bacillus subtilis\udsuspended in water (1 L ha-1) at sowing; T3 - Bacillus subtilis powder (1 kg ha-1\ud) inoculated seeds;\udT4 - Azospirillum (100 mL ha-1\ud) inoculated seeds; T5 - Azospirillum (100 mL ha-1\ud) + Bacillus (1 L ha-1\ud)\udin the groove. Analysis of nematodes in the roots of corn, fresh weight of shoots, ear weight and\udplant height were performed and evaluated crop yield. Sisvar the program to conduct statistical\udanalysis was used. For the analysis of variance F and Tukey test (5%) for comparison of means was\udused. There was no population control of plant nematodes evaluated during the experiment. The\uduse of Bacillus subtilis has supported development of the fresh weight of shoots in approximately\ud15% of corn in the off-season cultivation. The use of Azospirillum brasilense in the seeds increased\udby 21.9% corn yield compared to the control treatmen
