INVESTIGATION OF DIELECTRIC PROPERTIES OF PURE AND INSECTICIDE TREATED RICE SEEDS PUSA

The dielectric properties of Pusa rice seeds were determined insecticide treated and untreated rice seeds. The measurements were carried out with the help of Impedance gain phase analyser HP 4194 A and for maintaining the temperature of prepared samples a micro controller, Julabo F 25 was used. The investigation reveals that dielectric constant and dielectric loss both, treated in the ranges of 2-10% for moisture content, and 3–7 Hz for frequency of applied electric field using a coaxial capacitor sample holder. Effects of the parameters such as moisture content, bulk density and frequency on the dielectric properties were investigated. The dielectric constant, loss factor and conductivity were greatly affected by the moisture content, The moisture content was the most significant factor affecting the dielectric properties of rice seeds. The dielectric constant, loss factor and conductivity increased with insecticide treated rice seeds with some noticeable changes
