Experimental Investigation of Effects of Magnetic Water on Germination and Growth Rate of Coriander (Coriandrum sativum) in ex-vitro Conditions

Abstract

A magnetic field can be macroscopic in nature (current in a wire) or microscopic (current due to electrons in atoms) and it affects all living organisms since it is naturally a component of our environment known as the geomagnetic field. Various researches have shown that a plant’s overall growth and development is affected either positively or negatively by a magnetic field. Research has also shown that magnetic fields can also influence plant’s growth by applying it directly or indirectly. A cost-effective method of applying an indirect magnetic field to a plant is by magnetic water treatment, which is done by exposing ordinary water to a magnetic field and then irrigating the plants. The objective of this research was to determine the effects of magnetic water on the germination and growth rate of coriander in ex vitro conditions. There were 11 different treatments in this experiment including the control, with five different magnetic field strengths and two different exposure times for each magnetic field strength. The germination rate was observed and recorded after two weeks, while growth rate measurements were made starting from the third week after planting. Results showed that magnetic water treatment did not influence germination, but had a positive effect on the growth rate of coriander.
