Dep., Kashmar Higher Education Institute, Kashmar, IranJournal Article20181020 In order to study the effect of magnetic field and different levels of saline irrigation water on cumin yield, a factorial experiment with a completely randomized block design with three replications was carried out in Kashmar Higher Education Institute in 2016. In this experiment, four salinity levels of irrigation water; 0.5 (S<sub>1</sub>) as control, 6 (S<sub>2</sub>), 8 (S<sub>3</sub>), and (S<sub>4</sub>) 10 dS m<sup>-1</sup>, and two levels of magnetic field; magnetic water (M<sub>1</sub>) and non-magnetic water (M<sub>2</sub>) Were used. The results showed that the magnetized water increased the yield of cumin compared with non-magnetized water. So that the maximum grain yield of cumin (1085 kg. ha<sup>-1</sup>) was corresponded to S<sub>1</sub>M<sub>1</sub> treatment and the lowest one (530 kg ha<sup>-1</sup>) was corresponded toS<sub>4</sub>M<sub>2</sub> treatment. Also, the maximum and the minimum biological yields (2215 and 1295 kg ha<sup>-1</sup>) were corresponded to the same treatments (S<sub>1</sub>M<sub>1</sub> and S<sub>4</sub>M<sub>2</sub>) respectively. The yield reduction rates for 6, 8 and 10 dS m<sup>-1</sup> saline waters were calculated to be 7.8, 14.7 and 32%, respectively for the magnetic field and 6, 15.7 and 44.5%, respectively for the non-magnetic field as compared to the control treatment. In addition, the average water use efficiencies of saline and magnetic water treatments (0.5, 6, 8 and 10 dS m<sup>-1</sup>) were estimated to be 8.8, 6.5, 10.3 and 17.4% greater than the ones of saline and non-magnetic water treatments, respectively. Therefore, the use of magnetic water can increase the yield of cumin under salt stress conditions.
