In order to study of deficit irrigation levels on wheat grain yield cultivars based on Water Productivity Indices, an experiment was conducted in a split plot arrangement in Randomized Complete Block Design at the field of Agricultural and Natural Resources Center of Isfahan (Kabutarabad Research Station). Three levels of irrigations: 60% of full irrigation (F1) and 80% full irrigation (F2) and full irrigation (as the check) were assigned to main plots and six wheat cultivars including: Pishtaz, Shiraz, Sepahan, Marvdasht, Mahdavi and back cross of Roshan were randomized in sub plots. The maximum Total Water Productivity (TWP) were obtained from FI treatment (60% of full irrigation) with 1.51 kgm-3 and with 1.22 kgm-3 respectively. It means that decreasing of irrigation water rate, up to 40% due to 16.6% yield reduction totally. The highest Irrigation Water Productivity (IWP) were achieved from Pishtaz (1.19 kgm-3) and Sepahan cultivars (1.15 kgm-3) respectively.
