Abstract: The paper speaks to the investigation of dielectric constants alongside their loss factor for different sorts of grains which characterize their reactions against electromagnetic energy at various microwave frequencies by absorbing, radiates, reflect, and disperse a segment of electromagnetic energy. Estimation of dielectric consistent and loss factor have made for different specimens of grains, for example, Rice, Wheat, Split Red Gram (Arhar), Bengal Gram (Chana), Green Gram (Moong) for three unique states as preliminary, oven dried and saturated at various gravimetric moisture content in scope of CJ Band at two different frequency values (5.30 and 6.60 GHz) and furthermore in the scope of X Band at frequency of 10.65 GHz by utilizing waveguide cell (short-circuited lines or double minima or two point) technique. The general lab measurements are similarly critical in recognizing the grains and relatively increase the characterized crop productivity by using microwave remote sensing applications. The analytical study of various grains and pulses at microwave frequencies may give data about the vegetation field and furthermore distinguishes their behavioral properties.
