A field experiment was carried out at the Research Farm, Department of Agronomy, CCS HAU, Hisar, during the kharif seasons of 2023 and 2024 to investigate the effects of sewage sludge, FYM, and nitrogen levels on sorghum performance. The experiment was conducted using a split plot design, with sewage sludge (2.5 and 5 t/ha) and FYM (2.5, 5.0, and 7.5 t/ha) as the main factors. In subplots, four nitrogen levels were used (control, 50%, 75%, and 100% RDN) with thrice replication for statistical accuracy. Results showed during both years (2023 and 2024), application of sewage sludge @ 5 t/ha were taller plant, higher dry matter accumulation, yield (465.8 and 472.6 q/ha) and quality over 2.5 t/ha levels. Among FYM levels, significantly taller plant, higher dry matter accumulation, yield (468.4 and 475.7 q/ha) and quality were found with the application of FYM @ 7.5 t/ha over 5 and 2.5 t/ha FYM levels. Among nitrogen levels, application of 100% RDN were found significantly higher crop parameters viz. plant height, dry matter accumulation, yield (480.4 and 506.4 q/ha) and quality over lower levels and control. Integrated application of 5 t/ha sewage sludge, 7.5 t/ha FYM, and 100% RDN ensures optimal crop performance.
