Effect of integrated irrigation management on N;P;K elements variation in soils under (Pinnisetum glaucum L.) cultivation

In order to study th effect of irrigation with saline water under different methods on yield quantitative and qualitative characteristics of Sorgum. An experiment conducted in experimental farm of Islamic Azad University Shahr-e-Qods Branch. Experimental design Included four treatments included T1: Saline and fresh water treatment, T2: Alternative saline and fresh water treatment, T3: Mixed saline and fresh water treatment, T4: Control treatment. Result had show that the better yields stabilized on N,P,K Macronutrient in related to T1 treatment that the soil Nitrogen before giving treatment was 0.95 mg/kg reported and after irrigation in, T1; 9% , T2 ; 20% and T3; 37% decrease observed . Same result acquired in P and K percentages that showed T1 treatment is best choice of this experiment.
