Abstract

This study in order to evaluate the possibility of improving the root growth of lentil with use Mycorrhiza symbiosis with cooperation Azospirillum bacteria under rainfed conditions was conducted. A tri-factorial experiment was organized on the basis of Randomized Complete Block Design with four replicates, in which factor M was the Mycorrhizal inoculums in three levels including (not use, use Mycorrhiza Glomus intraradices and use Mycorrhiza Glomus mosseae), Factor A was Azospirillum in 2 levels including (not use and use Azospirillum brasilense) and factor L as the lentil cultivar with two levels consists of Mashhadi coarse grain cultivar and Naz fine seed cultivar.The results showed that the apply factor of Mycorrhiza, traits of root dry weight, percentage of root colonization and Mycorrhizal root dry weight at 1% level were significant. Also with apply Azospirillum Factor, percentage of root colonization trait at 1% level was Significant. The results survey the interaction between Azospirillum and Lentil cultivars showed that percentage of root colonization at the 5% level was significant. The results showed that the interaction Mycorrhiza and lentil cultivars on the percentage of root colonization at 1% level were significant. Also, three-way interaction Azospirillum, Mycorrhiza and lentil cultivars showed the percentage of root colonization trait at the 5% level was significant. Highest value for percentage of root colonization was recorded in treatment of use Azospirillum brasilense, use Mycorrhiza Glomus mosseae and Naz cultivar (46.19%).
