Organic farming is increasing in proportion every year with almost all cash crops being produced by it. Pulses also can be produced using organic farming. Four different samples of moong dhal grown by conventional farming and organic farming were collected and analyzed qualitatively using FTIR (fourier transform infrared) spectroscopy. Samples were conventional moong dhal, cheaper and easily available in market, organic white, organic green leaf and organic green complete moong dhal have been taken. Peak difference was observed in two major areas in the composition confirming the presence of additional functional group. Peaks of wavelength 2498 cm-1 which was present in conventional moong dhal and 550 cm-1 present in organic green leaf moong dhal showed significant difference when compared with other wavelengths as they are absent in any other of the sample. The effect of organic farming in case of moong dhal seemed to make no significant difference in their composition in comparison with the moong dhal produced by conventional faming.
