Magnetic Treatment of Irrigation Water and its Influence on Radish (Raphanus sativus) crop: A Green Technology

Abstract

Implementation of water treatment technologies for poor quality water may help reduce dependency on freshwater. One promising technology among water treatment technologies is magnetic water treatment (MWT). This study was aimed to evaluate the impact of bore water, hard water (1000 ppm) and saline water (electrical conductivity of 3 dS/m) on the plant biometric parameters and the yield of the radish. The water was treated in three stages: electrolysis, de-ionization and magnetization. In the pot culture experiment conducted, leaf length and leaf area index (LAI) was maximum under magnetized bore water treatment which was 22.7 cm and 6.2 compared to all other treatments respectively. The fresh weight (66.2 g) was highest in magnetically treated bore water, which was statistically significant over control. Among bore water treatments, the average yield per plant (48.5 t/ha) was maximum under magnetized bore water over control (43.9t/ha). Overall, the findings suggest that magnetically treated irrigation water positively influences plant growth parameters and the yield of radish.
