Abstract: 

In order to investigation the effects of mycorrhiza inoculation in different levels of irrigation and nitrogen on morphological and physiological traits of corn variety ksc 704 an experiment was carried out on factorial based on RCBD whit 3 replications. Experiments were done in research and education station of Islamic Azad University of Firouzabad branch in 2004. Results showed that simple effects of nitrogen, mycorrhiza, irrigation levels and interaction effect of mycorrhiza and irrigation levels and nitrogen on patterns such as plant height, shoot dry matter, root dry matter, leaf area and root length were significant. When mycorrhiza rose it caused increase of shoot and root dry matter and root/shoot ratio nitrogen fertilizer addition, increased shoot dry matter and root length of corn but also root dry matter was reduced by adding nitrogen. Root/shoot ratio and root length and percent of root colonization effected due to different levels of irrigation, in this case with increase of drought stress intensity, root length and percent of root colonization was decreased but ratio of root/shoot increased. Generally, the mycorrhiza growth response with drought stress intensity and root/shoot in mycorrhiza treatment toward check in drought stress were increased.
