Due to study of irrigation through sewerage water impact on corn forage functionality, a statistical layout with the title of Split Plot has been done that its main plot was four kind of irrigation water including; aqueduct water (SW), refined sewerage water (WW), aqueduct water as the start water and sewerage water from flowering stage (SW-WW), sewerage water as the start water and aqueduct water from flowering stage(WW-SW) and the sub plot was four different kind of corn including; Jeta, Kordona, Konsor and single cross 704. This study is done on the basis of three repetitions in Baharestan Industrial Complex. The result of analysis of heavy metals in corn’s body has shown that there is a significant difference in level %1 and %5 in accumulation of aluminum, copper, iron and nickel between the different samples under irrigation by WW-SW. Also the most amount of heavy metal accumulation between the four cultivars including aluminum, copper, iron and nickel was for Jota in order to 79, 10, 53, 102, 28 , ppm30 and the least was for Consor in order to 60, 8, 44, 93, ppm30 and the least accumulation of nickel was for Cordona with the amount of ppm14. Hence, concerning the above mentioned it is convenient to irrigate the plants with the combination of sewerage water and aqueduct water from the beginning in a defined proportion regarding the lands which have been irrigated through sewerage and aqueduct water. This way we will have the least amount of heavy metals accumulation in plants. There would be the most accumulation of heavy metals if irrigation is done through sewerage water first and then aqueduct water(WW-SW) and the reason could because of the rapid plant growing in flowering stage and the absorption of elements from water.
