The Effect of Dry Farming and Water Stress under Subsurface Drip Irrigation System on Water and Rice Productivity

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 complete block design, split plot replications. Determine depth depending moisture depletion soil, results showed difference depletion, which amounted 900 mm. Season-1 treatment for 10% decreased 10 16.6% prepared depleted, respectively. intervention treatments led significant increase grain yield using distance cm depleted. There were no differences I10 despite lines. efficiency crop use profitability outperformed I10.
