\begin{abstract}
\normalsize{
When freshwater is not sufficient for agricultural, industrial and municipal consumptions, inevitably will attract the attention of human towards other options that can in this regard be mentioned to municipal sewage effluent. Sewage effluent, is water very valuable that due to have organic and inorganic materials can have had an important role in fertility of agricultural land. The study was carried out to assess the effects of treated urban sewage and N on yield and grain quality of sweet corn (\textit{Zea mays} var. saccharata) and some soil characteristics in Yasouj. The main experimental factor consisted of 5 irrigation levels including: common irrigation water without sewage effluent until the end of plant growth (I1), the first half of plant growth period with sewage effluent and the second period with common irrigation water (I2), inverse of treatment I2 (I3), alternate irrigation with common irrigation water and sewage effluent till the end of the plant growth (I4), sewage effluent till the end of the plant growth (I5), and the sub factor was 3 N rates (N0=0, N80= 80 and N160=\mbox{160\,kg} N ha$^{-1}$) in a completely randomised design with three replications. Results indicated that the interaction of irrigation and nitrogen was significant on ear yield and canned grain yield. The highest fresh ear and canned grain yield were in treatment I5N80, as 2548 and 1246 gr m$^{-2}$, respectively. In general, application of sewage effluent reduced nitrogen fertiliser rate. A significant effect was noticed between consumed nitrogen and absorption of N and P in the grain. The soil N, P and K concentrations in treatment I5 had significant differences compared to the other treatments. Irrigation levels were also exhibited a significant increase in soil organic matter and EC. Maximum and minimum of soil organic matter were measured in I5 (\mbox{0.45\,\%}) and in I1 (\mbox{0.33\,\%}), respectively. Maximum of soil EC was noticed in I5 (2.0 dSm$^{-1}$). Irrigation treatments did not show a significant change in soil pH.}
