The Effect of Magnetic Field Intensity and Duration on the Amount of Nutrients Absorbed by Cucumber Transplant Moradali Ghanbarpouri1, Ahmad Mohamadi Ghahsareh*2, Mitra Attaabadi3, Mehran Hodaji4 PhD candidate, Department of Soil Science, Islamic Azad University of Isfahan, Iran Associate Professor, Department Soil Science, Islamic Azad University of Isfahan, Iran Assistant Professor, Department of Soil Science, Islamic Azad University of Isfahan, Iran Professor, Department of Soil Science ,Islamic Azad University of Isfahan, Iran *Corresponding author Email: mghehsareh@yahoo.com Received: 10 October 2021 Accepted: 8 January 2022 Abstract Over many years, the effects of magnetic fields on plant life have been the subject of different research studies. Recently, many authors have reported the effects of magnetic fields on the metabolism and growth of different plant species. In this study, in order to evaluate the effect of intensity and duration of magnetic field on nutrient uptake in cucumber transplant, cucumber seeds were treated with different values of magnetic field intensity and duration. The four levels of magnetic field intensity (0-80-140 and 240mT) and time exposure to the magnetic field were 5, 10, 15 and 20 minutes. After growth of seedlings after 5 leaf foliage, the chemical elements including manganese, zinc, copper, phosphorus, potassium, magnesium and total nitrogen were analyzed. The results showed that the concentration of Mn, Zn, Cu, K, Ca, Mg and N increased, while P and Fe decreased with increasing magnetic field intensity and duration of magnetic field exposure. The results show that iron, zinc, copper, phosphorus and potassium had the highest adsorption at 80 mT and 10 and 15 min, respectively. But phosphorus and potassium at 80mT for 15 and 5 minutes had the most effect on the absorption of these two elements, which increased with increasing magnetic field intensity. Calcium and nitrogen had the highest adsorption at 240 mM and 5 and 20 min, respectively. But the intensity and duration of the magnetic field had no effect on the absorption of magnesium in the transplant of cucumber.
