Abstract: 

In order to evaluation of nitrogen fertilizer application and seed inoculation by Azotobacter and Azosprillium on yield, rate and grain filling period of corn SC-500 cultivar, a factorial experiment was conducted based on randomized complete block design with three replications in farm of Agriculture and Natural Resource research center of Azarbaijan-e- Shargi province in 2011. The factors were included: nitrogen rates in four levels (0, 60, 120 and 180 kg/ha form urea) as N0, N1, N2 and N3 respectively and seed inoculation with rhizobacteria (without inoculation as control, seed inoculation with Azotobacter chrocococum strain 5, Azosprillium lipoferum strain OF). The results showed that maximum of nitrogen use efficiency (35.13 kg/kg) was obtained in application of 60 kg N/ha and minimum of it (23.37 kg/kg) was in application of 180 kg N/ha. Seed inoculation with bio fertilizers increased nitrogen use efficiency compared to no seed inoculation. Nitrogen rates and seed inoculation with bio fertilizers had significantly effects on yield and yield components. Maximum of grain yield (9313.3 kg/ha), grain weight (0.31 gr), rate (0.0089 gr/day) and grain filling period (54.37 day) were obtained in seed inoculation with Azosprillium ×180 kg N ha-1. So, in order to increasing of grain yield, rate and grain filling period can be suggested that be applied 180 kg N ha-1 × seed inoculation with Azospirillum lipoferum.
