THE EFFECTS OF MICROORGANISM VESICULAR-ARBUSCULAR MYCORRHIZAL (VAM) FUNGI ON SOME ADJECTIVES OF SORGHUM VARTIES

Mycorrhiza fungi (vesicular – arbuscular) or (VAM) make symbiotic association with crops and therefore are, enhances nutrient availability and uptake. The effects of different mycorrhizal fungi symbiosis with sorghum genotypes in 2006 – 2007 agriculture years were studied. This experiment was based of factorial experiment in the context of completely randomize design with two factors in four replication in field condition. The first factor was in 3 levels, including (KGS 25, KGS 29 and local race). The second factor was mycorrhiza in 3 levels including without mycorrhiza (M 0 ) and various species Glomus etanicatum (M1 ) and G. mosseae (M 2 ). The results showed that there are significant differences between cultivar of sorghum and using mycorrhiza on plant height, number of seed in spike, biomass, root colonization also the result indicates that in order augmentation of plant growth and crop yield it is necessary to choose the most effective fungus species. But .G. etunicatum species were best mycorrhiza strains among other administered ones
