Turf grasses have high water requirements during germination and growth and they must be irrigated constantly. If the condition of germination and growth improves, water could be saved. Tall festuca is one of the most important cool-season grasses in arid areas. Using magnet, carrier waves, static electricity, sound waves, etc. could influence some plants growth in specific conditions. In order to study the influence of flux density and different duration of magnetic field seeds of Festuca arandinacea were exposed to 0.5 mT and 5 mT magnetic fields and 50 mT static field for 5, 50 and minutes, respectively. The influence of magnetic field and electromagnetic on the percent of seed germination, germination rate and mean germination time were investigated. The results showed that no significant difference was observed between different treatments for seed germination percentage and mean germination time. Further research with optimized treatments is required to use this technology to improve festuca germination.
