Influence of Magnetized Seeds on Element and Microelement Intake of Green Gram (Vigna radiata L.)

Abstract

Building on the encouraging results from the initial cultivation of green gram under magnetic field treatments of varying intensities and exposure times, treatment T7 (225 mT for 75 minutes) proved to be the most effective. This treatment outperformed others in enhancing physiological traits such as germination rate, leaf area, shoot and root span, and plant height, accompanying improving chemical, biochemical, and yield-related parameters, including N, P, K, Fe, Mn, Zn, Cu content, chlorophyll a and b, carotenoids, acidity, vitamin C, and seed yield per plant. Further evaluation was conducted to assess how magnetic field exposure influenced the element intake of the plants. The absorption of key elements (N, P, K) and microelements (Fe, Mn, Zn, Cu) was quantified utilizing standard calculation methods. Statistical analysis confirmed that the combination of 225 mT magnetic field strength with a 75-minute exposure (T7) achieved the highest overall performance in the study.
