SUMMARY
A field experiment was conducted at Research Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar, Haryana, India during kharif 2023 and 2024 to assess the influence of sewage sludge, FYM and nitrogen on yield and agrometeorological indices of fodder sorghum. The experiment was laid out in split plot design with sewage sludge (2.5 and 5 t/ha) and FYM (2.5, 5 and 7.5 t/ha) in main plot, whereas, control, 50%, 75% and 100% recommended doses of nitrogen (RDN) in sub-plots with replicated thrice. Yield and agrometeorological indices viz. thermal use efficiency (TUE), photo thermal use efficiency (PTUE), helio-thermal use efficiency (HTUE) was significantly higher with the application of sewage sludge @ 5 t/ha and FYM @ 7.5 t/ha during both years. The 100% RDN treatment also showed significantly higher yield and agrometeorological indices viz. TUE, PTUE and HTUE during both years.
Key words: Agrometeorological indices, sorghum, fodder yield, TUE, PTUE, HTUE
