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.

Pulsed electromagnetic field effect on yield per plant. Seeds have been exposed for 0, 5, 10, and 15 minutes in magnetic field. Means followed by the same letter for treatments are not significantly different according to the LSD 5% test. Control: untreated seeds; MF-5, MF-10, and MF-15: seeds treated with pulsed electromagnetic field for 5 min, 10 min, and 15 min, respectively.

fig3: Pulsed electromagnetic field effect on yield per plant. Seeds have been exposed for 0, 5, 10, and 15 minutes in magnetic field. Means followed by the same letter for treatments are not significantly different according to the LSD 5% test. Control: untreated seeds; MF-5, MF-10, and MF-15: seeds treated with pulsed electromagnetic field for 5 min, 10 min, and 15 min, respectively.

Mentions: The presowing application of magnetic field had positive effects on yield parameters (Figure 3). In yield per plant measurement, MF-15 treatment (2448.8) gave the highest value, followed by MF-10 (2082.6), MF-5 (1845.6), and control (1353.5). All differences between treatments were statistically significant. Lycopene content measurements showed no statistically significant differences between treatments, although magnetic field treatments gave higher values than control. Plants derived from seeds treated for 15 minutes with magnetic field gave the highest value of lycopene content.
