In order to study the effects of deficit irrigation on tomato yield and to determine the production function and water use efficiency, an experiment was conducted based on randomized complete block design in three replications for two years, in Mazandaran province. Irrigation treatments were based on 0, 20, 40, 60, 80 and 100% of water requirements. The minimum and maximum yield belonged to I0 and I100 treatments. Water use efficiency and irrigation water use efficiency in I100 treatment was significantly higher than the other treatments. The results showed that the maximum yield of tomato occurred when full water requirement was provided. Therefore, I100 treatment with 5635 m3.ha-1 of water consumption and tomato yield of 45,020 kg.ha-1 was the best treatment and can be recommended to farmers where water resources are not limited. Water use efficiency (WUE) and irrigation water use efficiency (IWUE) were in the range of 5-9.25 and 9.2-14.6 kg m-3, respectively. The two-year average of yield response factor (Ky) for tomato was 1.18.
