Effects of treated water with neodymium magnets (NdFeB) on growth characteristics of pepper (Capsicum annuum)

Abstract

This study was conducted to investigate the effect of magnetic water treatment on growth characteristics of pepper (Capsicum annuum) plants. One week old pepper plants were selected and divided into four groups in a complete randomized design. In our study, we took normal tap water and divided it into four parts. The first group received given non-magnetically treated water (as a control), while the remaining groups received magnetized water at 3, 6, and 9 magnets, respectively. Four pipes and 18 permanent magnets with a flux density of 70 mT were used for this system. The results of the current study showed that magnetized water caused significant increases in all studied parameters, except plant length and dry weight, when compared to non-magnetized water. The results revealed that magnetizing water with 6 magnets was effective than others in increasing the number of fruits and leaves per plant, whereas magnetizing water with 9 magnets was effective than others in increasing the fresh weight of produces fruits. The impact of magnetic water treatment depends on the number of magnets used to magnetizing water. It appears that the utilization of magnetically treated water can lead to improving the quantity and quality of pepper fruits. Therefore, applying magnetized water could be one of the most promising ways to enhance agricultural production in an environmentally friendly way.
