Abstract

Two maize hybrids and their parent inbred lines were grown in sand culture with a nutrient media containing 3 concentrations of mineral N. Five bacterial strains isolated from maize rhizosphere were used for inoculation. Azotobacter inoculation affected not only maize dry weight but also N content. Finding indicated that Azotobacter, under certain conditions, stimulated the uptake of mineral N from a substrate. The effect of the association Azotobacter‐maize depended on maize form, Azotobacter strain, and N content in the nutritive medium.
