Potential Impacts of Certain N-Fixing Bacterial Strains and Mineral N Doses for Enhancing the Growth and Productivity of Maize Plants.

The enhancing effect of N-fixing bacterial strains in the presence of mineral N doses on maize plants in pots and field trials was investigated. The OT-H1 of 10 isolates maintained the total nitrogen, nitrogenase activities, IAA production, and detection of NH in their cultures. In addition, they highly promoted the germination of maize grains in plastic bags compared to the remainder.
