Abstract

The study executed in field Agriculture Collage – Al-Anbar University – alternative location in Abu Ghraib through term 30/7 up to 15/10/2015, in order the work of the experiment included activation and propagation mycorrhizal inoculum Glomus mosseae by using two hosts sorghum and sesbania plants, and the results summarized:- Significant superiority in infection rate amount to 26% by using mother inoculum G.mosseae to non-inoculum treatments with excellence infection rate root sesbania plant the highest infection rate a percentage 15.8% comparison with infection rate of sorghum roots. Investigating highest rate in total infected lengths roots, wet weight and dry ,that considered inoculum stimulating and product from treatment inoculum G.mosseae amount to 19, 64 and 60% respectively on the relay comparison non-inoculum treatment with excellence sesbania to result sorghum plant. Excellence the rate number spore mycorrhizal in soil inoculum amount to 22% to non-inoculum treatment, and excellence with sesbania plant rate amount to 82% on sorghum plant.
