the consequences of the application of mycorrhiza and azospirillum inoculants on yield and yield components of wheat cultivars

in order to study the consequences of the application of mycorrhiza and azospirillum inoculants on yield and yield components of wheat cultivars, 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 mycorrhiza fungi in three levels (no use of strain and using strain glomus intraradices and glomus mossaae), bacteria azospirillum lipoferum in the two-level (non-inoculated seeds and inoculated seed and too wheat cultivars in three levels, chamran (bread wheat), dena and behrang (durum wheat) varieties. survey the traits such as spike density, hectoliter weight, grain yield, productivity index and several other treats indicate a significant and positive effect on wheat cultivars. so that cooperation of mycorrhiza 7 to 33% and associative symbiosis of azospirillum 4 to 32% improved traits. however, concurrent use, led to increase the use of biological fertilizers effects on morphological traits of wheat. but the highest seed thousand weights (52 g), grain yield and biological yield, respectively (1246.33 and 3000.9 g. m2) was obtained from inoculation of c.v chamran seeds with azospirillum and g. mossaae and the highest number of days to heading (118 days) and hectoliter weight (803.31 g.lit-1) of bacterial inoculation chamran wheat and using g. intradices. thus it can be stated azospirillum and mycorrhiza for organic feeding of wheat bread and pasta, and are as suitable replacement for chemical fertilizers.
