Evaluation the morph physiological changes in wheat cultivars from the use of Mycorrhiza and Azospirillum

Resolution nutrient requirements in crops by non-chemical resource are new approach in production the organic crops. In order to study evaluation the morph physiological changes in wheat cultivars from the use of Mycorrhiza and Azospirillum, an experiment was conducted in the research station of Shahid Chamran University of Ahvaz, Iran in 2012-13. The experimental design was factorial based on randomized complete blocks design with three replications. The treatments including of bacteria Azospirillum lipoferum in the two-level (non-inoculated seeds and inoculated seed), Mycorrhiza fungi in three levels (no use of strain and using strain Glomus intraradices and Glomus mossaae), and wheat cultivars in three levels, (Chamran, Dena and Behrang). The results had indicated a significant and positive effect of microorganisms use on wheat cultivars for most traits. So that cooperation of Mycorrhiza 7 to 33% and associative symbiosis of Azospirillum 7 to 29% improved traits. However, concurrent use, led to increase the use of biological fertilizers effects on morphological traits of wheat. But the greatest plant height (103 cm), grain protein concentration (12.58%) and number of spikes per unit area (519 m2) was obtained from inoculation of C.V Dena seeds with Azospirillum and G. mossaae and the highest flag leaf length (29.33 cm), days to maturity (118 days), the yield of single plant (6.96 g) and spike length (9.33 cm) was obtained from inoculation of C.V Chamran seeds with Azospirillum and G. mossaae. Also the highest mycorrhizal dependency (32%) and Growth response (47%) was obtained from C.V Dena seeds with G. mossaae. So wheat nutrition with Azospirillum and Mycorrhiza can be been suitable replacement for chemical fertilizers.
