AbstractPots experiment carried out at college of Agriculture–university of Anbar during fall season 2012 to study effect of using cob of corn analyzed in growth of corn irrigated sewage treated by phosphate rock. This study including two factors was :irrigation water quality is. Fresh water (river water) w1and sewage treated by phosphate rock w2, no treated sewage w3. Second factor is ,organic wastes levels and forth levels is (O0) no added, (O1) 10 ton. hectar-1, (O2) 20 ton. hectar-1 and (O3) 30 ton.hectar-1 with three replicated using (RCBD).In the experiment end measured dry weight and plant heights were taken, also concentration of Fe, Mn, Zn, Cd for green part Decrease in dry weight for green part and plant heights when irrigated with no treated sewage it was values 42.01gm and 48.87 cm respectively, while increased in to 73.23, 74.60 gm and 85.17, 88.15 cm respectively with sewage treated by phosphate rock and fresh water. and Increase in dry weight with increasing organic waste levels it was 55.13, 63.33, 66.70, 67.97 gm respectively, as plant heights values 64.03, 75.60, 77.63, 78.99cm respectively with addition levels O0, O1, O2, O3. also Decrease of Fe, Mn, Zn, Cd concentrations for green part with irrigated sewage treated by phosphate rock it was 25.07, 25.40, 14.53, 0.19 mg.kg-1 respectively comparing no treated sewage it was values 30.62, 51.50, 23.02, 0.21 mg.kg-1 respectively. and Increasing of organic wastes level resulted Increase of Fe, Mn, Zn, concentrations in green part it was 29.54, 38.34, 19.08 mg.kg-1 respectively comparing with control. while decrease Cd concentration with organic wastes addition.
