Just before sowing, the seed of winter wheat was subjected to a single exposure to the pulsating electromagnetic field (PEMF) at different frequencies: 8, 15, 30 and 72 Hz. The duration of exposure was variable: 30, 60 and 90 minutes. Observations made during the growing season, analyses of yield and yield components and comparison with the untreated (control) revealed significant, mostly positive differences with regard to plant height, spike length and yield level. The highest yield was recorded in the treatment with 30 Hz for 30 minutes. The study findings indicate that different frequencies and exposure times of PEMF have different effects on plant growth development and hence, biochemical processes in plants.
