Abstract
To determine the effects of saline water with and without magnetic treatments on seed emergence and yield of wheat, two experiments were conducted in the National Salinity Research Center, Iran. The first experiment was done under controlled environment conditions with day and night temperatures of 25 ◦C and 15 ◦C, respectively. The emerging wheat seeds were measured under four irrigation water qualities including 2.5, 6, 10 and 12.7 dS/m with and without magnetic device. To determine the effect of magnetic treatment on wheat yield under saline conditions, another experiment was done in 18 fiber glass boxes (0.5 x 0.45 x 0.50 m deep) in the ambient environment for two years. Treatments included use of magnetic device (Model: MAG 4000) and without it and three water qualities (2, 6 and 10 dS/m). Results showed that salinity treatments had no significant effect on final emerged seeds and emergence percentage. However, salinity significantly reduced rate of emergence, coleoptile length, grain yield, plant height, spike length, and the number of kernels per spike. Magnetic treatment and interaction between magnetic treatment and salinity had no effect on the number of emerged plant, emergence rate, emergence percentage, coleoptile length, grain yield, plant height, spike length, and number of kernels per spike. These results were obtained using a specific magnetic device. Probably, using a different magnetic device with different composition of irrigation water applied to various crops may lead to different results.
