A field experiment was conducted on 20/7/2019 in one of the farms of the Al-Jelaweya village (30 km north of Babylon province), To study the effect of mineral fertilizers (Nitrogen, Phosphatic and potassium) and either bio fertilizers (Agrosoil- N that contains the Azotobacter and the Mycorrhiza (Glomus mosseae) separately and collectively on the synthetic cultivar. 5018 yellow corn in terms of growth and production, Mineral fertilizers were at three levels. As for bio fertilizers at two levels, the experiment was conducted using the Randomized complete block design (RCBD). The following results showed: Nitrogen fertilizer (Urea 46% N) excelled, giving the highest averages for plant height, leaf area and, chlorophyll content and total yield (183.22 cm, 540.22 cm2, 54.44 spad, 5.41 ton/ ha), while phosphate fertilizer P2O5 excelled on The 500 grains weight and giving the highest averages, it reached 152.23 g. As for the bio fertilizer Agrosoil-N, it gave the highest values for the traits of plant height, leaf area and chlorophyll content, and the total yield was (183.36 cm, 612.82 cm 2, 52.04 spad, 5.060 tons / ha. Whereas, the treatment of two bio fertilizers gave the highest averages on all studied traits (193.38 cm, 572.06 cm 2, 58.22 spad, 153.59 g and 5,590 ton/ ha. The interaction between mineral and bio fertilizers (N2 x bio fertilizer together) excelled on all traits except for the 500grain weight trait as treatment (P2 x bio fertilizer together) excelled and gave the highest averages.
