Abstract: This study on spectral behaviour of red soil of Maharashtra under various levels of organic matter was conducted in the laboratory of Department of Soil Science and Agriculture Chemistry, VNMKV, Parbhani in 2018. One and half kilogram of red soil (S2) was mixed with six levels of vermicompost viz. V0: No vermicompost, V1:100 gm vermicompost, V2: 250 gm vermicompost, V3: 500 gm vermicompost, V4: 1 kg vermicompost and V5: 1.5 kg vermicompost making total 6 treatment combinations to create different levels of organic matter and colour shades. These different combinations were exposed for spectral reflectance studies and observations were taken by SVC GER 1500 Spectro radiometer. The readings (% reflectance) were taken for corresponding wavelengths (nm) of Red and NIR bands. It was noticed that with increase in vermicompost to red soil there was decrease in reflectance. It is found that S2T1 and S2T2 i.e. red soil 1.5 kg + 100 gm VC and red soil 1.5 kg + 250 gm VC showed higher reflectance at all wavelengths than S2T3, S2T4 and S2T5 (i.e. addition of 500 gm, 1kg and 1.5 kg of vermicompost, respectively). Red soil made two clear cut zones of reflectance. 1.5 kg red soil with 1 kg and 1.5 kg vermicompost recorded minimum reflectance. While addition of lower amount of vermicompost i.e. 100, 200 and 500 gm depicted higher reflectance from wavelength 550 to 850 nm. Red soil showed maximum Red reflectance at 658 to 660 nm band and NIR reflectance at 858 to 860 nm.
