The present field experiment was demonstrated during kharif season of 2023-24 using cotton variety Rasi (RCH 386 BG II) as a test crop in vertisol with three replication and ten treatments viz, T₁ - Absolute Control, T₂ - RDF (150:75:75 NPK kg ha^-1 + S@25 kg ha^-1), T₃ - 75% RDF + 50% CTF, T₄ - 75% RDF + 75% CTF, T₅ - 75% RDF + 25% CTS, T₆ - 50% RDF + 50% CTS and T₇ - 25% RDF + 75% CTS, T₈ -75% RDF + 3% Foliar application of Jeevamrut, T₉ -75% RDF + Soil application of Jeevamrut ( @ 500 lit/ha at 30-45 DAS).T₁₀ -75% RDF + 0.5% Humic acid (Seed treatment).The compost tea and jeevamrutha prepared and applied as foliar spray at 30, 75 and 120 DAS and as soil drenching at 30 and 45 DAS. The obtained results reported that foliar application of compost tea as 75% RDF + 75% CTF noted significantly indicated that application of 75% RDF with 75% CTF to cotton was found superior for increase in growth and yield of cotton and reduce up to 25% RDF. Among all the treatments, T₄ - 75% RDF + 75% CTF significantly increased the organic carbon, available N, P2O5, K2O, S, Cu, Fe, Mn, Zn in the soil. However, pH, EC and calcium carbonate was found non significant after harvesting of the because these properties don’t change in one cropping system.
