• Wheat is one of the staple foods of the global population due to its adaptability to a wide range of environments. Nitrogen is one of the crucial limiting factors in wheat production and is considered a challenge to food security. Therefore, sustainable agricultural technologies such as seed inoculation with plant growth-promoting bacteria (PGPBs) can be adopted to promote biological nitrogen fixation (BNF) for higher crop productivity. In this context, the objective of the current study was to evaluate the effects of nitrogen fertilization and seed inoculations with and + on agronomic and yield attributes, grain yield, grain N accumulation, N use efficiency and applied N recovery in Brazilian Cerrado, which consists of gramineous woody savanna. The experiment was carried out in two cropping seasons in Rhodic Haplustox soil under a no-tillage system. The experiment was designed in a randomized complete block in a 4 × 5 factorial scheme, with four replications. The treatments consisted of four seed inoculations (control-without inoculation, inoculation with and + ) under five N doses (0, 40, 80, 120 and 160 kg ha , applied from urea) at the wheat tillering stage. Seed co-inoculation with + increased grain N accumulation, number of spikes m , grains spike and grain yield of wheat in an irrigated no-tillage system of tropical savannah, regardless of the applied N doses. Nitrogen fertilization at a dose of 80 kg ha significantly increased grain N accumulation and number of grains spikes and nitrogen use efficiency. Recovery of applied N was increased with inoculation of and co-inoculation of + at increasing N doses. Therefore, N fertilization can be reduced by the inclusion of co-inoculation with + in the cultivation of winter wheat under a no-tillage system of Brazilian Cerrado.
