Abstract:
Magnetic fields are known to induce biochemical changes and could be used as a
stimulator for growth related reactions, to enhance growth, chemical constituents and
productivity of crops.The method of magneto-hydro dynamical activity of natural water
is an essential part in the whole complex of using magnetic fields in agriculture. It
includes physical- chemical changes of natural water parameters, resulting in
improvement of filtration properties and in an increase of dissolving properties of water.
These changes result in an increased ability of soil to get rid of salts and results in a better
assimilation of nutrients and fertilizer in plants during the vegetation period.
Water treated by magnetic field or passed through a magnetic device is called
magnetic water .The study examines the effect of magnetic treatment of different
irrigation water types on growth and yield of Amaranthus. Replicated pot experiments
using
magnetically
treated
and
normal
tap
water
and
saline
water
(EC=1mmhos/cm,2mmhos/cm and 3mmhos/cm) were conducted under controlled
environmental conditions. A magnetic treatment device with magnetic field of intensity
0.9360T was used for the magnetic treatment of irrigation water. The analysis of data
collected from the study revealed that the effect of magnetic treatment varied with the
type of irrigation water used and there was a statistically significant increase in plant
yield with magnetised irrigation water.
