Bottom Line: Yield per plant was higher in magnetic field treatments, compared to control.MF-15 treatment yield was 80.93% higher than control treatment.Lycopene content was higher in magnetic field treatments, although values showed no statistically significant differences.

ABSTRACT
The use of magnetic field as a presowing treatment has been adopted by researchers as a new environmental friendly technique. The aim of this study was to determine the effect of magnetic field exposure on tomato seeds covering a range of parameters such as transplanting percentage, plant height, shoot diameter, number of leaves per plant, fresh weight, dry weight, number of flowers, yield, and lycopene content. Pulsed electromagnetic field was used for 0, 5, 10, and 15 minutes as a presowing treatment of tomato seeds in a field experiment for two years. Papimi device (amplitude on the order of 12.5 mT) has been used. The use of pulsed electromagnetic field as a presowing treatment was found to enhance plant growth in tomato plants at certain duration of exposure. Magnetic field treatments and especially the exposure of 10 and 15 minutes gave the best results in all measurements, except plant height and lycopene content. Yield per plant was higher in magnetic field treatments, compared to control. MF-15 treatment yield was 80.93% higher than control treatment. Lycopene content was higher in magnetic field treatments, although values showed no statistically significant differences.

Mentions: Tomato seeds were treated by Papimi electromagnetic field generator for 5, 10, or 15 minutes before planting. Seeds that were not treated have been used as control. Papimi device is a pulsed EMF generator (Figure 4). (Papimi model 600, Pulse Dynamics, Athens, Greece. Manufacturer characteristics: 35–80 J/pulse energy, 1 × 10−6 s wave duration, 35–80 × 106 W wave power, amplitude on the order of 12.5 mT, rise time 0.1 ms, fall time 10 ms, and repetitive frequency of 3 Hz.) The same device has been used in agricultural studies [13].
