چکیده:

In the recent years use of sewage sludge as a fertilizer has become prevalent in agricultural lands, because of it is cheap. Sewage sludge issource of nutritional elements.The aims ofpresent study were to The effect of sewage sludge on soil chemical properties and growth of Secale montanum and Vicia faba with andwithout present of Arbuscular mycorrhiza fungi. The experiment was conducted in controlled conditions was completely randomized designand factorile test. Three levels of sewage sludge (0, 100 and 200 ton/ha) , two levels of mycorrhiza (with and without mycorrhiza) andtwo plant (Secale montanum and Vicia faba) in three replicated were used. Organic matter, total N and P content were measured. The resultshowed that as the added sewage sludge increased , organic matter, total N and P content in soil with mycorrhizal plants and control ones, but organic matter, total N and P were much higher in soils with mycorrhizal plants. As the added sewage sludge in soil that treated by 100ton/ha, organic matter, total N and P content in soil and plants tissues increased but organic matter, total N and P in soil and plants tissueswere higher in mycoorhizal plants than nonmycorrhizal ones.With increase sewage sludge in soil in treated by 200 ton/ha, organicmatter content in treated soil and plants tissueSecale montanum and Vicia faba are increase. Contents of organic matter, total N and P werehigher colonized plants than control ones
