Main outcome of study (acc. to author)

The data showed that the magnetic field pre-treatment significantly increased the germination percentage, number of flowers per plant, leaf area, plant height at maturity as well as the number of fruits, pod mass and number of seeds per plant. The magnetic field exposure for 11 minutes showed better results than the sham exposed control or the exposure for 3 minutes.
