Effect of inoculation of maize (Zea mays L.) cultivars KSC704 with Mycorrhizal fungi and Pseudomonas bacteria on yield and biochemical traits in condition of cut irrigation

Bio-fertilizers of bacteria and fungi that are useful are produced each specific purpose, such as nitrogen fixation, release of phosphate ions, potassium and iron insoluble compounds of them. An experiment to study the effects of Mycorrhizal fungi (Glomusmosseae) and Pseudomonas bacteria (Pseudomonasputida) on yield under drought stress, antioxidant enzymes and biomarkers destruction of the corn plant KSC704 varieties in crop year 2013-2014 was conducted in Varamin. The experiment was a split plot in a randomized complete block design with three replications were studied. The main factor of three irrigation levels (1- Normal irrigation. 2. Cut irrigation in the flowering stage. 3- Cut irrigation at grain filling) and Bio-fertilizer mixing sub Mycorrhizal fungi and Pseudomonas bacteria to the seeds when planting at four levels (1. non-use of Mycorrhiza and Pseudomonas. 2. The application of Mycorrhizal 60 g.ha-1. 3. Application of 100 g.ha-1 Pseudomonas. 4. Application of Mycorrhizal fungi and Pseudomonas) was considered. The results showed that the interactions between stress and the use of Mycorrhizal fungi and Pseudomonas on all traits was significant at the level of one and five percent. The highest grain yield (7965.3 kg.ha-1), biological yield (20468.3 kg.ha-1) and harvest index (39.1 %) were obtained with simultaneous application of Mycorrhizal fungi and Pseudomonas and normal irrigation and The least of these traits of stress during flowering and non-use of Mycorrhizal fungi and Pseudomonas allocated to that with drought stress during grain filling was no significant difference. It should be noted in irrigation and Application of Mycorrhizal fungi and Pseudomonas usually the least amount of catalase, D-OH guanosine and malondialdehyde were obtained. The highest amount of leaf prolinein the amount of 0.336 µg.g-1 in irrigation cut off at flowering stage and the application of Mycorrhiza and Pseudomonas was obtained. Simultaneous use of Mycorrhizal fungi and Pseudomonas conditions of drought stress on the growth, the plant could greatly increase your tolerance through increasing adaptability metabolites
