Evaluation effect of water stress and nitrogen rates on amount of absorbtion some macro and micro elements in corn plant mycorrhizae and non mycorrhizae

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 three replications in 2008 in research and education station of Islamic azad university of firouz abad on corn k s c704. 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 absorbtion 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. © 2010, American Eurasian Network for Scientific Information.
