For optimal water management in tomato cultivation an experiment was conducted in a randomized complete blocks design with three replications in research farm of Jiroft in Kerman. In this experiment four suction levels (I1=35, I2=45, I3=55 and I4=65 centibar) were compared. The results showed that the used water in total course of growth with mentioned suction levels was respectively 6550, 5470, 4510 and 3490 cubic meters per hectare. Performance obtained from studied treatments also showed that irrigated treatment with suction level of 45 centibar has the highest performance (44.21 tons per hectare) and suction levels of 35, 55 and 65 centibar respectively have the performance of 37.44, 44.22 and 27.62 tons per hectare.
