The effect of plant growth-promoting rhizobacteria (PGPR) belonging to the genera Azospirillum and Azotobacter on the growth and nutrient uptake of maize (Zea mays) was investigated in the field as factorial experiment. Azospirillum strains were: Z0 = no inoculation, Z1 = Azospirillum sp. Strain 21, Z2 = Azospirillum lipoferum DSM 1691, Z3 = Azospirillum brasilense DSM 1690 and Azotobacter strains were: A0 = no inoculation, A1 = Azotobacter sp. Strain 5, A2 = Azotobacter chroococcum DSM2286. Treatment with PGPR(s) significantly increased plant height, shoot and seed dry weight, ear dry weight and length and number of seeds per row. Plants nutrient uptake of N, P, K, Fe, Zn, Mn and Cu were also significantly influenced by application of PGPR(s). These results indicate some PGPR inoculants have the potential to increase maize growth yield and nutrients uptake.
