Summary:Abstract A field experiment was carried out during the 2020 season at the College of Agricultural Engineering/ University of Baghdad, Al-Jadriya to evaluate the effect of dry farming when applying water stress under the subsurface drip irrigation system on water productivity and rice yield. The experiment was conducted with three levels of irrigation water stress when 10, 20 and 40% of the available water was depleted and in three dimensions between drip lines 10, 15 and 20 cm. The experiment was designed according to a randomized complete block design, according to the split plot design, with three replications. Determine the depth of irrigation water depending on the moisture depletion of the soil, the results showed a difference in the depth of water according to the moisture depletion, which amounted to 900 mm. Season-1 treatment for 10% depletion and decreased to 10 and 16.6% when 20 and 40% of the prepared water was depleted, respectively. The intervention between drip lines and irrigation treatments led to a significant increase in grain yield when using a distance of 10 cm and irrigation when 10% of the available water was depleted. There were no significant differences in grain yield at I10 despite the difference in the distance between the drip lines. The efficiency of field and crop water use and the profitability of water outperformed I10.
