A field experiment entitled “Influence of bio-fertilizer and nitrogen on growth and yield of hybrid maize (Zea mays L.)” was conducted in 2012 at the Agronomy Experimental Farm of the College of Agriculture, Central Agricultural University, Imphal. The experiment consisting of four nitrogen levels (0, 60, 120 and 180 kg N/ha) and three source of bio-fertilizers (control, Azotobacter and Azospirillum) was laid out in factorial randomized block design with three replication. The required quantity of nitrogen (60,120 and 180 kg/ha), phosphorus (60 kg/ha) and potash (40 kg/ha) were applied for each plot using Urea, SSP and MOP. Application of different levels of nitrogen and sources of bio-fertilizers exhibited significant differences in growth characters, yield contributing characters and yield. Application of nitrogen up to 120 kg/ha showed significant increase in yield contributing characters as well as the grain yield with an exception in test weight. Among the bio-fertilizers, Azotobacter resulted in significantly higher growth characters, yield contributing characters and yield than Azospirillum and control. The interaction effect between nitrogen and bio-fertilizer was found to be significant in all the characters considered. The treatment combination of 180 kg N/ha + Azotobacter or Azospirillum inoculation recorded higher grain and stover yield which remained at par to 120 kg N/ha + Azotobacter. Based on the results obtained from the experiment, it can be concluded that application of 120 kg N/ha and Azotobacter can be recommended for hybrid maize to get high yield.
