“…6A). Data obtained in studies of the effect of extremely low frequency (ELF) fields on plants [Wittekind et al, 1990;Muraji et al, 1992;Ružič et al, 1998] showed that for every frequency there might exist so-called ''windows'' for intensity, exposure time or modulation. Our results suggest radio and microwave EMFs could exhibit the same effect.…”

Increased use of radio and microwave frequencies requires investigations of their effects on living organisms. Duckweed (Lemna minor L.) has been commonly used as a model plant for environmental monitoring. In the present study, duckweed growth and peroxidase activity was evaluated after exposure in a Gigahertz Transversal Electromagnetic (GTEM) cell to electric fields of frequencies 400, 900, and 1900 MHz. The growth of plants exposed for 2 h to the 23 V/m electric field of 900 MHz significantly decreased in comparison with the control, while an electric field of the same strength but at 400 MHz did not have such effect. A modulated field at 900 MHz strongly inhibited the growth, while at 400 MHz modulation did not influence the growth significantly. At both frequencies a longer exposure mostly decreased the growth and the highest electric field (390 V/m) strongly inhibited the growth. Exposure of plants to lower field strength (10 V/m) for 14 h caused significant decrease at 400 and 1900 MHz while 900 MHz did not influence the growth. Peroxidase activity in exposed plants varied, depending on the exposure characteristics. Observed changes were mostly small, except in plants exposed for 2 h to 41 V/m at 900 MHz where a significant increase (41%) was found. Our results suggest that investigated electromagnetic fields (EMFs) might influence plant growth and, to some extent, peroxidase activity. However, the effects of EMFs strongly depended on the characteristics of the field exposure.

“…In addition, they showed that applying MF to broad bean during the growing season can increase the number of pods per plant and reduce the plant losses per unit area. Several studies have demonstrated the effectiveness of MFs on the root growth of various plants [14][15][16][17][18] . Similarly, Muraji et al (1992) observed that MF treatment increases the root growth of maize 18 .…”

Magnetic water treatment (MWT) techniques have shown promising potentials in different areas specially agriculture. Safety, compatibility and simplicity, environmentally friendliness, low operating cost and not proven harmful effects are the main advantages of electromagnetic field (EMF) over conventional methods for water treatment. Magnetized or magnetic water (MW) possesses unique physical and chemical characteristics making it a multi-purpose compound with potential benefits in medical treatment, industrial as well as environmental applications. The unique physical and electrochemical characteristics of MW have attracted research interests to develop different devices and techniques in agricultural and environmental applications. Improvements of irrigation water quality and quantity, crop yields and quality, soil improvement and water saving are some of the reported benefits of MWT in agriculture. In addition, magnetic field treatments have shown beneficial effects on the germination of seeds, plant growth and development, the ripening and yield of field crops. The main challenge in applications of MW in agriculture is efficient integrating of irrigation components, designing suitable pumps compatible with technical and field requirements of magnetic MWT systems. The present study reviews the applications of MW in agricultures. The practical challenges in using MW as well as future perspective are discussed.

“…The effect of electric field to the growing of rice plants has been studied [1], [2] for example, the studies about effect of electric field from 300 kV DC transmission line to rice plants growing [3], bending effect on the growth of the primary root of rice [4] and in the past the study about effect of magnetic field on the growth of primary roots of corn [5], have been reported. In this study the primary root of rice are experimented under the condition with electric field varied in the horizontal direction at 28.5 kV/m and without electric field, while various timing for 8, 16 and 24 hour and increasing the number of sample then investigated the bending effect on the growth of primary root.…”

The growing of rice seeds (Oryza sativa L.) on a primary root stage are experimented under the condition with electric field at 28.5 kV/m varied electrode in horizontal direction and without electric field. This work is focused on the bending of the root direction were measurement the space angle after 8, 16 and 24 hour. These values with E-field and without E-field are compared. The result indicate that the majority direction of root is bended to negative electrode.
