Effects of using subsurface drip irrigation and treated municipal waste water in irrigation of tomato

Abstract

Whenever good quality water is scarce, water of marginal quality will have to be considered for using in agriculture. Municipal waste water is marginal quality water and using of this for irrigation can be an important consideration when its disposal is being planned in arid and semi-arid regions. In this study, secondary municipal effluent was used for irrigation of tomato. This effluent is using activated sludge process to treat the municipal wastewater. Five different irrigation treatments were designed with three replications. The treatments were as follows: Tl: Furrow irrigation with drinking water network. T2: Surface drip irrigation (DI) with treated wastewater. T3: Sub surface drip irrigation (SDI) in 15 cm depth with treated wastewater. T4: Sub surface drip irrigation (SDI) in 30 cm depth with treated wastewater. T5: Furrow irrigation with treated wastewater. Crop water requirement was determined by ET-HS model. Also, in…
