| Abstract | ||
| A field experiment was conducted under central pivot irrigation system at KirkuU governorate sterilized seeds of {Zea mays L.) c.v. IPA 5012 were inoculated with Azosirillum brasilienses and Glomus mosseae in single and combined application under three levels of organic fertilizer. The results showed that grain yield significantly increased with increasing the levels of organic fertilizer and the highest grain yield was achieved at combined inoculation of A. brasilienses + G. mosseae. The highest yield was 5790 T/h as compared with control 2115 T/h. The incrementin grain yield could be attributed to the significant increase in the number of grain , kernel as well as to weight of 1000 grains. The nutrient content of N, P, K in leaves as well as the residual values of these nutrients in soil were markedly influenced by the level of organic fertilizer and the methods of inoculation . Iron , Zinc and Copper contents in leaves were significantly increased with combined inoculation of A. brasilienses and with highest levels of organic fertilizer. | ||
