Abstract

We tested the effect of a large number of diazotrophic strains from the genera Azotobacter, Klebsiella, Escherichia, Derxia, Beijerinckia, and Azospirillum, on nitrogen concentration in four corn hybrids. The range obtained, from highly significant positive to highly significant negative effects, indicates that the strains studied differed in their characters, including the capacity to form useful associations with certain hybrids. The forming of positive associations depended on the specificity of diazotrophic strains and corn hybrids.
