An experiment was carried out during Kharif, 2022 and kharif 2023 at Research Farm of Department of Agril. Botany, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra to investigate the influence of various liming sources (No lime, calcium carbonate, dolomite and calcium hydroxide) and levels of sulphur (0, 30, 45 and 60 kg ha^-1) on microbial population in soil of groundnut cv. Konkan Bhuratna (Arachis hypogaea L.) grown in lateritic soil of Konkan region of Maharashtra. The experiment was laid out in Factorial Randomized Block Design with sixteen treatment combinations, which were replicated thrice. The results revealed that the application of calcium carbonate (367.88 and 372.28 x 10⁵ cfu g^-1 soil) and sulphur @ 60 kg ha^-1 (361.25 and 358.25 x 10⁵ cfu g^-1 soil) showed highest bacterial population. The highest fungal population observed due to application of no lime (22.13 and 22.38 x 10³ cfu g^-1 soil) and no sulphur (21.50 and 21.38 x 10³ cfu g^-1 soil) in soil. The highest actinomycetes population recorded due to application of calcium carbonate (68.50 x 10⁵ and 70.50 x 10⁵ cfu g^-1 soil) and sulphur @ 0 kg ha^-1 (64.38 x 10⁵ and 70.75 x 10⁵ cfu g^-1 soil) in soil during the kharif 2022 and kharif 2023, respectively.
