Abstract: A field experiment was conducted on “Effect of sources and levels of sulphur on physic-chemical properties and available nutrient status of Niger (Guizotia abyssinica) growing soil during the year 2015-16 at College of Agriculture, Latur. The experiment was laid out in randomized block design with twelve treatments and three replications. The results of field study indicated that the organic carbon and available nutrients of Niger growing soil were significantly influenced by application of different sources (ammonium sulphate, elemental sulphur and gypsum) and levels (10, 20 and 30 kg ha^-1) of sulphur. The significantly highest organic carbon (0.95 g kg^-1) content, available N (156.53 kg ha^-1), P (28.44 kg ha^-1), K (537.62 kg ha^-1) and S (23.92 kg ha^-1) were recorded than the other treatments with RDF+ S 30 kg ha^-1 through ammonium sulphate (T₆) followed by the application of RDF+ S 30kg ha^-1 through gypsum (T₁₂). The soil pH, EC, calcium carbonate after harvest of Niger were decreased as compare to initial value but the organic carbon, available N, P, K and S content were increased in soil samples collected after harvest of Niger than the initial soil sample.
