Abstract :

In order to investigate the effect of biological fertilizers on yield and yield components of bean, a field study was conducted during spring and summer 2010 in research farm of college of Arak Islamic Azad University.The factorial experimental of the study comprised of RCBD with three replications. Three varieties of bean were Goli (indeterminate), Sayad (Semi determinate) and Derakhshan (determinate). Mycorrhiza fungi including no inoculation and Glomus intraradices and three levels of Rhizobium phaseoli were including: no application strain Rb116 and strain Rb133. interaction between mycorrhiza, rhizobial and cultivars on yield and yield components showed highest grain yield and biological yield, respectively, with the 2664 kg/ha and 6333 kg/ha of the treatments inoculated with mycorrhiza (Glomus intarardices and rhizobial strains Rb131 and goli variete was obtained. The lowest yield of the treatments used mycorrhiza fungi and rhizobial bacteria zero levels, with 1172 kg/ha and Derakhshan variete was obtained.
