Electromagnetic field and seed vigour of corn hybrids med./bio.

Published in: Int Agrophys 2010; 24 (3): 329-332

Aim of study (acc. to author)

To test whether exposure of maize seeds to magnetic fields could increase the corn productivity.

Background/further details

Three corn hybrids were exposed to a magnetic field for 0, 3, 6, 9,12 or 15 minutes (25 seeds per experimental condition).

Main outcome of study (acc. to author)

No significant differences between the germination of the control group and of the exposed groups were observed. Additionally, no significant influence of the magnetic field exposure on the length of the seedling was found. Regarding the dry mass, significant increases were observed in the exposed groups when compared to the control group. Seeds from the exposed group showed a higher emergence rate than those from the control group (except for the group examined after 9 days and exposed for 12 minutes),
The different corn hybrides showed different responses to the magnetic fields: The emergence rate at day 9 of San Juan and San Jeronimo was significantly increased with 3 and 6 minutes exposure in comparison to the control group. The dry mass of San Jeronimo was significantly increased after a 3 minutes exposure and of San Juan after 9 minutes exposure compared to the control, while San Jose showed no response to the magnetic field.
The authors conclude that exposure of maize seeds to magnetic fields could be applied as a pre-sowing treatment to promote the growth of the seedlings.
