Effect of Mycorrhiza fungi Glomus etunicatum on growth characteristics of barley which grown in nutrient solutions

This study was conducted at agricultural of plant production laboratories. The factorial experiment included studying the effect of two factors :First one : Urea at concentrations of (0 , 10 and 10 mg L-1 ) dissolved in tap water second factor : Treated with Mycorrhiza (Glomus mosseae) in seeds of barley .A Completely Randomized Design (C.R.D.) were used with four replicates and means were compared according to L.S.D. test at the level of 0.05. The results were summarized as follows: Mycorrhiza treatment was significantly superior in germination % ,plant height, fresh and dry weight of shoots and root s (41.3%, 10.44cm, 13.7g, 7.02g, 18.5g, 10.13g plant-1 ) respectively as well as Urea treatment(0.25g .L-1 ) was significant and superior compared to other treatments in fresh weight of vegetative and roots (6.5, 18.6 g.plant-1 . Results also indicated that the interaction of Mycorrhiza with urea 0.25g.L-1 had a significant increase in most of the studied indicators .
