The use of inoculants containing growth-promoting diazotrophic bacteria can stimulate mass and nutrient accumulation in sugarcane. The purpose of this study was to evaluate plant growth and accumulation of macroelements in sugarcane, variety RB92579, under bacterial inoculation with or without N fertilization. The field experiment was carried out in a Red-Yellow Podzolic soil in Seropédica, RJ, in a randomized block design with four replications. The treatments consisted of 50 kg N ha -1 ; 50 kg N ha -1 + inoculation; inoculation; and an absolute control. The following bacteria were inoculated: Gluconacetobacter diazotrophicus, Herbaspirillum seropedicae, Herbaspirillum rubrisubalbicans, Azospirillum amazonense, and Burkholderia tropica. The plants were sampled at 100, 130, 168, 212, 261, and 295 days after planting (DAP), and growth and nutrient accumulation rates were estimated by functional analysis of plant growth. Nutrient accumulation rates were highest around 180 DAP for N and P, and around 160 DAP for K, in the different treatments, preceding the maximal crop growth rate (between 210 and 220 DAP). The accumulation of biomass, N, P and K was greater and crop growth rates were higher in the treatments with bacterial inoculation fertilized or not with 50 kg N ha -1 , compared with the control.
