Abstract: In order to determine the effect of mycorrhizae in some macro and micro elements in water stress condition and different nitrogen rate. The experiment was carried out by using a randomized complete block design in 3 replications in 2008 in research and education station of Islamic azad university of firouzabad on corn KSC 704. The results showed that mycorrhizae increased significantly the absorbtion of nitrogen, phosphorous and potassium in shoot and in root too. Treatment of irrigation levels affected in 1% probability on absorbtion of all elements of nitrogen, phosphorous, zinc copper, iron and manganese with increase of water stress intensity nitrogen, phosphorous and manganese absorption was decreased. But potassium, iron, copper, zinc absorbtion was increased in similar water stress, mycorrhizae treatment showed an increasment in relative absorbtion of nitrogen, phosphorus, potassium, copper and zinc. With increase of nitrogen in mycorrhizae and nonmycorrhizae treatments absorbtion of nitrogen, phosphorous manganes and a little potassium increased but iron decreased and it has not any certain process about other elements.
