A study was carried out to investigate the effects of deficit irrigation on yield components of rice (Binam variety). The experiment was run in the form of a randomized complete block design with nine treatments and three replications in the Babolsar city of Mazandaran province in year 2020. The treatments were regulated deficit irrigation (RDI) and partial root zone drying (PRD) in three drought stresses of 10, 30 and 60 kPa (RDI10, RDI30, RDI60, PRD10, PRD30 and PRD60) and full irrigation (FID). Drip tape irrigation system was used as irrigation method. Flood irrigation system was used as an irrigation (FI1) and weed (FI2) control treatment. Soil water deficit was measured by a tensiometer and Volumetric meter was used to calculate water consumption. Flood irrigation treatment had the highest yield of rough rice and water consumption (6442 kg / ha and 10886 m3 / ha). The lowest rice yield was for RDI60 treatment with 2998 kg / ha and the lowest water consumption was corresponded to PRD60 treatment with 2111 m3 / ha. According to the results, the applying of PRD method in addition to higher yield than RDI, saved 76.33% in water consumption. The PRD method could be recommended for the region.
