Effects of Treated Municipal Wastewater on Growth Parameters of Corn in Different Irrigation Conditions

K. Asgari, P. Najafi, A. Soleymani and R. Larabi
In order to calculate the effects of using treated municipal wastewater on quantity of yield in Corn, this study was conducted in 2003, at experimental farm in south treatment plant in Isfahan. The experimental was randomized complete block design with five treatments and tree replications were used. Treatment were: Furrow irrigation with drinking water network (T1), surface drip irrigation with wastewater (T2), subsurface drip irrigation with wastewater in 15 cm depth (T3), subsurface drip irrigation with wastewater in 30 cm depth (T4) and furrow irrigation with wastewater (T5). Results indicated that, subsurface drip irrigation with wastewater in 30 cm depth as compared to other treatments had higher growth parameters and had seen significant difference. Thus, drip irrigation with wastewater and furrow irrigation with wastewater, had lower growth parameters as compared to another treatments. In T4, plants absorb water and essential elements, better than other treatments because irrigation source is near the root zone.
