The effect of biofortification with Iron and Zinc on agronomic traits of mycorrhizal barley

The main resaon for the low quality and quantity yield of plants is Lack of attention to nutrition with micro-nutrients on poaceae family and other crops. In order to investigate the effect of Iron, Zinc and mycorrhiza on barley yield and yield components, a field study was conducted during 2013-14 years in agricultural experimental station of Islamic Azad University Arak branch. A factorial experiment was arranged in randomized complete block desing with three replication. Three Levels of Zn, Z1 (no application), Z2 (25 kg/ha-1) and Z3 (50 kg/ha-1) were used. Mycorrhiza fungi including no inoculation and Glomus intraradices and three levels of Iron (no application, 2/5 kg/ha-1 and 5 kg/ha-1) were used. Simple effect of Mycorrhiza on yield showed highest grain yield with (3.90 ton/ha-1) was obtained from Glomus intraradices. Highest levels of straw yield with 3.43 was obtained in treatment Glomus intraradices. The simple effect of mycorrhiza, Iron and Zinc showed the highest biologic yield with 6.91, 6.70, 6.49 was obtained in treatment Glomus intraradices, 5 kg/ha-1 Iron and 100 kg/ha-1.
