N applied in topdressing, the treatments inoculated provided higher values in the recovery of the applied N (**Table 7**, **Figure 6**). There was adjustment to the linear decreasing function, regardless of inoculation or not with *A. brasilense* (**Figure 6**). In the unfolding between N sources and inoculation, in the absence of inoculation with *A. brasilense*, urea provided higher RAN compared to Super N. When the N source used was Super N, inoculated treatments provided higher RAN compared to those not inoculated (**Table 8**), that is, this compensated

FE was not influenced by N rates, N sources, and inoculation with *A. brasilense* (**Table 6**), which is explained by the adequate growth of the plant (dry‐matter accumulation) even when no N was supplied due to adequate N leaf concentration in all treatments (**Table 1**), as previ-

The interaction between inoculation and rates was also significant in AE, when the rates of 50, 100, and 200 kg ha−1 of N were applied; the inoculated treatments with *A. brasilense* had higher AE compared to the non‐inoculated treatments, which is a very good result (**Table 9**) because it indicates that there were smaller losses of N with this diazotrophic bacteria inoculation. There was adjustment to the linear decreasing function of AE with and without *A. brasilense* as a function of N rates (**Figure 6**). Pankievicz et al. [38], studying FBN with ammonia release by associative fixers, verified increase and development of the *S. viridis* root

plants cultivated in a nitrate‐limited environment similarly developed under N sufficient conditions, elucidating the ability of some mutant strains to increase BNF and positively interfering with the carbon metabolism of C4 plants, which has a close relationship with the assimilatory metabolism of N in the plant. Therefore, considering that in the experimental area, there was a favorable condition to the microbial immobilization of the applied N, and this explains why there was a higher AE of the treatments inoculated as a function of the N

The interaction between N sources and inoculation in AE was significant. In treatments inoculated with *A. brasilense*, urea and Super N provided higher AE compared to uninoculated treatments. In the absence of inoculation, urea provided higher AE compared to Super N (**Table 10**).
