In traditional paddy production, large water losses may occur due to drainage, evaporation and deep percolation (groundwater is highly polluted). In addition, while production costs increase, it also decreases in production areas. This study has been researched together with the usability of the drip irrigation method (DI) to reduce the global footprint of water in paddy production and its economic analysis. In the experiment, two irrigation intervals (2 and 4 days), four irrigation water levels (75, 100, 125 and 150% of cumulative Class A Pan values) and three different paddy genotypes (Baldo, Osmancik and Ronaldo) were investigated. In the research, irrigation water between 513-820 mm was applied to the treatments. Actual Evapotranspiration (ETa) values are 565-855 mm; The Crop Water Productivity (CWP) ranged from 0.84-1.35 kg ha-1 m-3 and the Irrigation Water Use Efficiency (IWUE) ranged between 0.95-1.49 kg ha-1 m-3. Economical water productivity (EWP) was calculated between 0.79-1.24 $ m-3 and the cost-benefit (B/C) ratio was calculated between 1.11-2.33. When the traditional cultivation method, the ponding method in the pan, is compared to the province, it has been determined that water savings are between 70-81%. Yield according to branches was measured as 4882-10305 kg ha-1. According to the results of the research, up to 29% yield increase was achieved under the condition of applying 150% of the cumulative evaporation every 2 days.
