This work evaluated the electromagnetic effects on germination of corn Zea mays, seed usually cultivated in the municipality of Ocaña (North Santander, Colombia), whose common name is described as pullita corn. Three treatments were carried, one with 945 MHz (Megahertz frequencies), other with 440 MHz and a witness one, all of them with three repetitions. Such wave emissions were made with half wave antennas, located at a distance of 37 cm from the substrate to which the seeds were planted. The electromagnetic radiation emitted was 24 hours a day, for 8 days and the results showed statistically significant differences; observing after those eight days a germination rate of 92%, 80% and 50%, and past 15 days 98%, 95% and 84%, for treatments with wave emissions of 945 MHz, 440 MHz and the witness ones, respectively. Likewise, low percenta­ge of ash was observed in comparison to witnesses, having results of 12,69%, 16,17% and 18,45%. In terms of height, it was observed in the early days, a gain in length for plants subjected to the highest frequencies, followed by the lowest frequency and the witness. For the last day a greater height was noted for lower frequency, followed by the highest frequency and the witness.
