AbstractDue to limitation of water resources the use of wastewater for agriculture and landscape isessential The wastewater is a new water source and its application requires specialmanagement If wastewater be used with a suitable irrigation method it can contemporarilyreduce environmental contaminations hygienic and water scarcity problems To evaluatethe application of the porous pipe with two types of water groundwater and wastewater and their effects on physical and chemical properties of soil an experiment was carried outat Mahmoudabad Research Centre in Isfahan for Bermudagrass The experiment wasfactorial completely randomized design with two main treatments of surface and subsurfaceirrigation methods and two sub treatments of fresh water and wastewater Each treatmenthad three replications Also the effects of irrigation under different pressures of 0 4 0 8and 1 2 atmosphere were studied The results showed that subsurface irrigationsignificantly increases the EC Na Zn and Mg of the first layer of soil 0 15 cm ascompared to the surface irrigation In subsurface irrigation as compared to the surfaceirrigation the EC of the second layer 15 30 cm and third layer 30 60 cm was less Alsoirrigation with groundwater increases the salinity of second and third layers as compared tothe irrigation with wastewater There is a significant difference between wastewater andgroundwater in the second layer P 0 05 The amount of Mg OM and K in the first andsecond layers irrigated by wastewater is significantly greater than those irrigated bygroundwater The appearance and chemical characteristics of turf showed that applicationof wastewater does not have significant difference on colour density of turf and absorptionof N Fe and Zn by turf Irrigation with wastewater has significant effect on height yieldand K and P uptake of turf as compared to the groundwater The irrigation methods have nosignificant effect on turf characteristics The results showed that the pressure significantlychanges porous pipe discharge P 0 05 The application of wastewater increases thedischarge of porous pipe and this increase is significant in pressure of 0 4 atm P 0 05 Also the effect of time on discharge was significantly different P 0 01 The results oflaboratory experiments showed that the discharge uniformity of porous pipe decreases withincreasing the applied pressure
