Abstract :
In order to study the response of yield components of Safflower to inoculation of Azotobacter and Mycorrhiza in the Arak region, The experimental was conducted as factorial on based of RCBD in three replications during 2012 in research farm of college of Arak Islamic Azad university.Treatments including of inoculated with Azotobacter in three levels (Non-inoculated with Azotobacter, inoculation with Azotobacter-5 and inoculation with Azotobacter-12) and mycorrhiza treatment in four levels (Non-inoculated with mycorrhiza,inoculation with Glomus intraradices, inoculation with Glomus Mossae and inoculation with mixed G.intraradices and G.mossae).Effect azotobacter was significant on traits number of grain per capitule at 5% probability level and grain yield and harvest index of sub-sub capitule at 1% probability level.Effect mycorrhiza was significant on traits number of grain per capitule, grain yield and harvest index of sub-sub capitule at 1% probability level.Also effect interaction azotobacter and mycorrhiza was significant on traits plant height, number of capitule per plant,number of grain per capitule, grain yield and harvest index of sub-sub capitule. Result showed that highest grain yield equal to 1333 kg.ha-1 was obtained from treatment of non-inoculated with Azotobacter and inoculation with mycorrhiza Glomus mossae and the lowest grain yield equal to 828.3 kg.ha-1 was obtained from treatment of non-inoculated with azotobacter and mycorrhiza.
