Magnetic water treatment (magnetic treatment device (MTD)) has long been a contentious procedure for domestic water treatment. This study examines the pros and cons of using different water types with and without a magnetic field treatment for growing French bean crop irrigation. The MTD used in this experiment works by ionizing the dissolved solid using a cathode and anode, electrolysing water using a dynamic pulse current at 50 kHz, and energizing the cations using a 7,000 Gauss magnet. The MTD of normal, waste and saline water enhanced the yield by 12.7, 16.9, and 20.07% over their respective control plots. Contrarily, seed protein (22.52 g/100 g), vitamin A (687.09 IU), potassium (212.44 mg/100 g), vitamin K (14.32 mg/100 g), and calcium (39.93 mg/100 g) reached their peak values when French bean plants were irrigated by magnetically treated wastewater. Na concentration in pods was significantly reduced when 3,000 mg/L of magnetically treated saline water was used to irrigate French bean plants. The MTD of irrigation water has also improved N and K desorption from colloidal soil complexes, which significantly helped make these two elements easily available to the plants and promoting better plant growth and yield. Overall, using the MTD, the overall characteristics of French bean were improved. HIGHLIGHTS Importance and the positive effect of magnetically treated water on crop growth, yield, and quality parameters were demonstrated.; Increase in the efficiency of growth and productivity of French bean grown under environmental stresses by using magnetized water.; The magnetic treatment device (MTD) of irrigation water has also improved N and K desorption from colloidal soil complexes.;
