A field experiment, entitled “Impact of Different Organic and Inorganic Fertilizers with Varying Sulphur Doses on Growth and Yield of Onion (Allium cepa L.) In Bilaspur, Chhattisgarh region” was conducted at Instructional Farm, Department of Vegetable Science, College of Agriculture, BTC CARS Bilaspur (Chhattisgarh) during Rabi 2019 and 2020. The soil of experimental site was clay in texture, (Vertisols) with pH 7.21, low in organic carbon (0.37%), low in available N (219.00 Kg ha^-1), medium in available P (14.70 Kg ha^-1), and high in K (360.40 Kg ha^-1) contents. Temperature and other weather conditions remained favourable throughout the growing season of the crop. The onion variety N-53 was sown on nursery 10 October, 2019 and transplanted on 22 November, 2019 with a spacing of 15 cm x 10 cm using experimental techniques of Randomized block design with three replications. Treatment comprised of twelve different agro input management practices viz., treatments 100 % RDF (T₁), 75% N through RDF + 25% N through FYM (T₂), 50% N through RDF + 50% N through FYM (T₃), 100% RDF + 20 Kg S (T₄), 75% N through RDF + 25% N through FYM + 20 Kg S (T₅), 50% N through RDF + 50% N through FYM + 20 Kg S (T₆), 100% RDF + 30 Kg S (T₇), 75% N through RDF + 25% N through FYM + 30 Kg S (T₈), 50% N through RDF + 50% N through FYM + 30 Kg S (T₉), 100% RDF + 40 Kg S (T₁₀), 75% N through RDF + 25% N through FYM + 40 kg S (T₁₁) and 50% N through RDF + 50% N through FYM + 40 Kg S (T₁₂). Recommended agronomic practices were followed for raising crop. The crop was harvested on 18^th April, 2020. Impact of Different Organic and Inorganic Fertilizers With Varying Sulphur Doses had significant effect on growth, yield attributes and yield of onion. 75% N through RDF + 25% N through FYM + 40 kg S (T₁₁) resulted in better growth and yield attributes significantly superior at last observation Highest plant height (56.03 cm), Maximum number of leaves plant^-1 (11.43), Length of Leaves (51.60 cm), Total soluble solid (13.02 °Brix).
