Dielectric constant (ε), dielectric loss (ε) and conductivity (σ) of some oil seeds (namely Brassica Compestris Yellow and Black) have been measured over the range of temperature 15- 45°C with varying frequency from 5 KHz to 10 MHz. The effect of change in the moisture content and varying concentration of micro-fertilizers on dielectric properties has been studied. Both the dielectric constant and conductivity were found to increase with increase in moisture level and also with increasing concentration of micro-fertilizer. The dielectric parameters show a decreasing trend with increase in frequency. The dielectric constant, dielectric loss and the conductivity of the dead seed has also been measured and compared for both the varieties.
