Abstract
Applying soil N fertilizer is a crucial factor for maximizing maize (Zea mays L.) grain yield. Maize hybrids have been found to positively respond to high amounts of applied soil N; yet high-applied soil N amount results in reduced N use efficiency (NUE), develops more environmental problems, and augments grower economic inputs. One way to compensate for using excessive N fertilizers is to apply non-symbiotic seed-inoculated nitrogen fixers. Therefore, the main objective of this experiment is to study NUE and its components
