Magnetic treatment of irrigation water: Its effect on water properties and characteristics of eggplant (Solanum melongena

Abstract

Poor quality water is a potential source for demand management in irrigated agriculture after essential treatment. Magnetic water treatment (MWT) is one of the emerging technologies among water treatment methods for the above-cited problems without harming the environment. The optimum configuration of the 7000 gauss magnetic treatment device and the effect of magnetized water on the yield parameters of the eggplant in a pot culture experiment were examined in this study. The maximum significant (P< 0.05) changes in physicochemical properties (pH, EC, total hardness, Langelier Saturation Index, Na, etc.) of water occurred at an optimized velocity of 0.8 m/s and less. The mean plant height was maximum under magnetized bore water treatment compared to all other treatments (P< 0.05). In particular, the average yield per plant was increased by 17 per cent in magnetized bore water treatment compared to the control. Overall, the results have shown that an optimum configuration of the water treatment device is needed before the start of the experiment based on magnetic strength. Moreover, magnetically treated irrigation water positively impacted plant growth parameters and the yield of the eggplant.
