Serratia spp., strain BRM 32114, is a plant growth-promoting rhizobacteria that show strong potential to solve two major challenges of upland rice production in a no-tillage system: initial vigor and grain yield improvement. No-till practices dictate the sustainability of cropping systems as they improve precipitation use, sequester C, mitigate atmospheric CO2 enrichment, restore soil health, and stimulate interest in crop diversity and rotation design. This study was intended to analyze the effect of the Serratia spp. on growth promotion and grain yield improvement in upland rice, under four N rates. Two field experiments were conducted during growing seasons 2015/2016 and 2016/2017, in two different experimental areas managed under a no-tillage system in the Brazilian Cerrado soil. The experimental design was a complete randomized block in a 4 × 2 factorial scheme, with four replications. Treatments comprised of four N fertilizer rates (0, 40, 80 and 120 kg N ha-1) with or without BRM 32114. In BRM 32114 treatment, rice seeds were microbiolized and bacterial suspension were sprayed at soil/plant in the field on the 7th and 15th DAS (day after sowing). Morphophysiological (gas exchange, shoot nutrients content and biomass production), and agronomic (grain yield and its components) traits were estimated. Results revealed increase in stomatal conductance (~ 20%); N, Ca and Mg (7, 11 and 9%) contents; shoot dry matter (8%); number of grain per plant (17%); mass of 1000 grains (2%) and yield (~ 22%) in BRM 32114-treated rice and cultivated in soil fertilized with 0, 40 and 80 kg N ha-1. However, the efficacy of this strain was reduced when combined with the highest rate of N (120 kg ha-1) added to the soil. It is possible to get higher yields levels of upland rice, cultivated under no tillage system, with the complimentary use of Serratia sp., strain BRM 32114, than the application of chemical fertilizers alone. The improvement in soil health could be extra benefit for fertilizer' savings.
