This study was carried out to determine the effect of different irrigation treatments and economic analysis on surface and subsurface methods in amaranth under the Mediterranean climate conditions at the experimental fields of the Alata Horticulture Research Institution during 2018 and 2019 growing seasons in Turkey. In the study, surface drip and subsurface drip methods and six irrigation strategies (Full irrigation, FI; conventional deficit irrigation, DI-50 and DI-75; DI-25; Partial Root-Zone Drying, PRD-50 of full irrigation treatments and Rainfed) also a rain-fed treatment (RF) were considered. There was significant differences (P<0.01) for yields both irrigation system and irrigation method. Maximum yield was obtained from the FI treatment as 3,790 and 3,950 kg ha^-1 ; and the lowest yield was obtained from the rainfed treatment (RF) as 1,840 and 1,960 kg ha^-1 , in the experimental years, respectively. The experimental design was split plots with four replications. Net profit ranged between 9,143 to 18,047 $ ha^-1 in 2018 and 9,742 to 19,454 $ ha^-1 in 2019 according to the irrigation treatments. Full irrigation treatment (FI) under subsurface drip irrigation method generated the highest net profit
