Abstract A field experiment was carried out during the 2020 season at College of Agricultural Engineering/ University Baghdad, Al-Jadriya to evaluate effect dry farming when applying water stress under subsurface drip irrigation system on productivity and rice yield. The conducted with three levels 10, 20 40% available depleted in dimensions between lines 15 cm. designed according a randomized ...

Subsurface drip irrigation (SDI) can substantially reduce the amount of irrigation water needed for corn production. However, corn yields need to be improved to offset the initial cost of drip installation. Air-injection is at least potentially applicable to the (SDI) system. However, the vertical stream of emitted air moving above the emitter outlet directly toward the surface creates a chimne...

Agricultural irrigation in the middle reaches of the Heihe River Basin consumes approximately 80% of the total river water. Whether the irrigation depth matches the water uptake depth of crops is one of the most important factors affecting the efficiency of irrigation water use. Our results indicated that the influence of plastic film on soil water δ(18)O was restricted to 0-30 cm soil depth. B...

In this study, the influence of relevant parameters a subsurface pipe layout on soil water and salt transport in cotton field under mulched drip irrigation is explored. Based measured data changes groundwater level field, DRAINMOD numerical model has been used for simulating dynamics salinized drainage. The results investigation show that can accurately simulate hydrological conditions salt-lea...

Scarcity of fresh high-quality water has heightened the importance of wastewater reuse primarily in dry regions together with improving its efficient use by implementing the Subsurface Drip Irrigation (SDI) method. Sustainable effluent reuse combines soil and plant aspects, along with the maintainability of the application system. In this study, field experiments were conducted for two years on...

Agricultural soils are important sources of greenhouse gases carbon dioxide (CO 2 ) and nitrous oxide (N O), as well nitric (NO), a precursor to tropospheric ozone. Management approaches that constrain these emissions can limit future warming improve regional air quality, especially in high-temperature agroecosystems where soil high. Subsurface drip irrigation is promising management solution v...

In order to assessment of SDI system application in the condition of wastewater reuse, three treatments with three replications were design. These treatments included check treatment with drinking water (CH), surface drip irrigation with wastewater (DI) and subsurface drip irrigation with wastewater (SDI). In addition, before pipeline, a SDI filtration designed to improve biological index of wa...
