Effect of multi-periodic and chaotic magnetic fields on plants’ growth from germination to harvest: experiment on bean (phaseolus vulgaris)

In this work, we studied the impact of electromagnetic fields of various periods on the germination, growth and production of bean (phaseolus vulgaris). The magnetization of the seeds was carried out as soon as it was placed underground in field conditions. Plant growth until pod formation was monitored under field conditions on an experimental surface of 10.0 m 2 . The electrical circuits used for magnetization made it possible to obtain electromagnetic fields of period 1, 2 and 4 as well as a non-linear or chaotic electromagnetic field. Daily 24-hour exposure with these different signals has influenced some growth parameters.  The height difference was significant (at P <0.05) for the comparison between A0 and A2. We found a production time saving of approximately ten (10) days for the A4 treatment compared to the control treatment A0. Experience has shown that plants subject to the chaotic field (A5) formed the largest number of pods. The comparison between the maximum number of pods formed and the number of pods that reached maturity for each treatment showed pod losses during the last growth phase. The loss rate was 29.25%, 28.31%, 35.78%, 64.38% and 62.72% respectively for A0, A1, A2, A4 and A5 treatments.
