The Effect of Magnetic Water on Growth, Essential Oil Yield, and Some Phytochemical Properties of two Dill populations (Anethum graveolens L.) 151 167 21390 10.22034/saps.2024.62545.3254 FA Sepideh Houshmand Department of Horticulture, Faculty of Agriculture, University of Tabriz Saeideh Alizadeh- Salteh Department of Horticultural Science, University of Tabriz Sahebali Bolandnazar Department of Horticulture, Faculty of Agriculture, University of Tabriz Journal Article 2024 07 18 <strong>Background & Objectives:</strong> Nowadays, stimulating plants using magnetic fields is considered a method to enhance the quantity and quality of agricultural products. Therefore, the magnetic properties of water were utilized to treat the medicinal plant dill, reducing the use of chemical fertilizers. This method is scientific, simple, and organic.<br /><strong> </strong><br /><strong>Materials and Methods:</strong> The effect of magnetized water at two magnetic field intensities (0.1 and 0.2 Tesla) and a control treatment, in four replications, was evaluated on two populations of dill (Tabriz and Varamin).<br /><strong> </strong><br /><strong>Results:</strong> Magnetized water significantly increased the vegetative and reproductive traits of dill. It had a significant impact on the number of umbels, umbellules, secondary branches, leaves and also the length and diameter of the root and stem, resulting in a 20% increase in root diameter. Additionally, the suitable water quality and solubility of elements in water enhanced the fresh and dry weight of the root and stem. The magnetic water treatment significantly increased the levels of flavonoids, total phenols, anthocyanins, vitamin C, and protein. Furthermore, considering the importance of essential oil in this medicinal plant, magnetic water increased the weight and volume of essential oil.<br /><strong> </strong><br /><strong>Conclusion:</strong> Our results indicated that using magnetic water as a physical treatment can be an effective tool to enhance the nutritional and medicinal value of dill. It offers a natural method to improve growth and stimulate. The increase in biological performance, given the enhanced vegetative growth and production of secondary metabolites without the use of fertilizers and pesticides, makes the economic performance justifiable.<br /> <br /><strong><em> </em></strong> <strong>Background & Objectives:</strong> Nowadays, stimulating plants using magnetic fields is considered a method to enhance the quantity and quality of agricultural products.
