Evaluation of possibility improving growth and yield of lentil with use symbiosis Mycorrhiza and Azospirillum under Rainfed Condition

A field experiment was conducted aiming to determine the possibility of improving the lentil performance as co-inoculated with Vesicular Arbuscular Mycorrhiza (VAM) fungi and Azospirillum under rain-fed conditions. 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 (not use¡ use Glomus intraradices and use Glomus mosseae)¡ Factor A was Azospirillum in 2 levels (not use and use Azospirillum brasilense) and factor L as the lentil cultivar with two levels (Mashhadi and Naz cultivars). The results showed that the effect of Mycorrhiza on traits of root dry weight and Mycorrhizal root dry weight was significant at the 1% probability level.Highest value for root dry weight and Mycorrhizal root dry weightwas recorded in plants inoculated with Glomus mosseae.Also¡ Azospirillum and Lentil cultivars were not significanteffect on all traits.The results showed that the interaction between Azospirillum and Lentil cultivars on seed yield at the 5% probability level was significant.
