Abstract:

In recent years, water deficit and environmental hazards of wastewater have promoted the development of wastewater reuse in irrigation of agricultural lands in many arid and semi-arid regions. An experiment was conducted out at the experimental farm of a leaven factory, where the effect of treated wastewater on yield and yield components of wheat (Triticum aestivum L.) was studied during the growing season of 2012. Three, irrigation levels (I1: irrigation with wastewater once in whole experimental period, I2: irrigation with wastewater twice in whole experimental period and I3: irrigation with wastewater in whole experimental period) and six wastewater percentage levels (C1: 15% wastewater, C2: 30% wastewater, C3: 45% wastewater, C4: 60% wastewater, A: pure water and P: pure wastewater) were studied in a randomized complete block factorial design with three replications. Results illustrated that number of irrigation with wastewater did not have significant effect on plant height, grain number per spike, grain yield and harvest index while it had significant effect on spike number, 1000-seeds weight and biological yield. Also results showed that wastewater percentage did not have significant effect on spike number, grain number per spike, grain yield, biological yield and harvest index although it had significant effect on plant height and 1000-seeds weight. The maximum increase of biological yield was observed in irrigation with wastewater in whole experimental period.
