Some macro nutrients uptake optimizing by effect of Mycorrhizae fungi in water stress condition in sorghum plant

摘要

In our time human need to agriculture as ever, but it has many more bad environmental effects. Nutrients are the materials of production in agriculture and remove of them is one of the chemical fertilizers more using inducement which provoke removing and it's a grate restriction for environment, but its partly avoidable by increasing the plants absorption. Plants, during the period of growth and development are exposed to environmental stresses. One of the most important stresses is water stress. Which can make problems for plants Absorption and transmission of nutrition, but some kinds of useful terricolous fungis such as Mycorrhizae can naturally effect on this process which is matched with environmental protection objectives. The experiment was carried out in pot to determine symbiotic effect of Mycorrhizae and also effect of this microorganism in water stress on absorption of elements in sorghum plant .This experiment was carried out in factorial by using a randomized complete block design in three replications in 2009 in Shiraz-Iran. The results showed that water stress can effect significantly on Nitrogen and Phosphorus and Potassium absorption. Also Mycorrhizae significantly increased the absorption of Nitrogen, Phosphorus and Potassium.
