Resumo: | This study aimed to investigate the interaction between the bacteria A. brasilense and H. seropedicae associated with nitrogen fertilization, aiming to supply nitrogen for corn crop. The experimental design was randomized blocks, in 4 x 3 factorial design with four replications. The first factor was formed by the treatments: no inoculation, inoculation H. seropedicae and A. brasilense in isolation and combination of the two strains. The second factor referred to nitrogen levels, 0, 60 and 120 kg ha-1 of N. Each experimental plot consisted of six corn lines of 3.5 meters, where the evaluation of yield components was performed: number of rows grain and number of kernels per row, thousand grain mass, average mass of grains per spike and productivity. Isolated inoculation with the bacteria A. brasilense (AbV5) and H. seropedicae (SMR1) resulted in gains especially for thousand grain weight, which can be observed that for less than the maximum dose of nitrogen doses, remained the same yield. There were no gains in productivity with respect to the use of corn seed inoculation with rhizobacteria of the genus A. brasilense (AbV5) and H. seropedicae (SMR1) in relation to nitrogen fertilization.
