A field experiment was carried out through summer of 2017 in Kirkuk university-Agricutural experimental research station in Al-saiada to planting pop corn as factorial experiment in RCBD design with three replicates ، every replicate included(14) factorid treatment as acombination between studed factors ،the organic fertilization with humic acid was in two levels، first by adding and other with out adding ، as arrange 16kg/h.

after 20 days the other half after 40days from planting، while the second factor was combination from bio-fertilizer included Azotobacter، Azospirillum as single، and Azotobacter and Azospirillum by adding 20N، Azotobacter and Azospirillum with adding 40Nand the recommendation fertilizer 60kg N with adding to it.The result showed that the treatment of humic acid caused to significaut in creasing in 50% of female flowering (66.57day).

weight of 300 kernels(41.19gm)to tall grain yield(165.6gm/plant) and harvest index(0.45).

The treatment Azospirillum+40 showed significantly surpass in plant (2.46).

The treatment Azospirillum was surpassed in number of ear rows (15.05).

number of ear grains(567).

Harvest index(0.47%)While the treatment Azotobacter was surpassed in exploding ratio(98.66%)and male and female flowering(59.66 and 63.83 days) respectively.

While the treatment Azotobacter+40N was surpassed in protein ratio(3.14%).

The interaction between humic acid with Azospirllium alone and Azotobacter alone or by adding levels of nitrogen recommended nitrogen amuomunt was surpassed in number of ear rows (15.70) and male with female flowering (59.66 and 64.00 days) respectively.

Weight of 300 kernels(42.66 gm) number of ears per plant(2.53) and protein percentage (3.18%).
