SUMMARY
A field experiment was carried out during kharif -2023 at Research Farm, Department of Soil Sciences, CCS HAU, Hisar (India) to assess the effect of organic and inorganic source of nutrients on growth parameters and fodder yield of sorghum. The experiment was laid out in split plot design with three sorghum varieties (CSV 53F, HJ 541 and Duggi) in main plot and nutrient management treatments (T1: Control, T2: 100% RDF, T3: 125% RDN + 100% RDP+ 100% RDK, T4: FYM @ 15 t/ha, T5: Vermicompost @ 5 t/ha, T6: 100% RDF + FYM @ 15 t/ha and T7: 100% RDF + Vermicompost @ 5 t/ha) in sub plot. For forage sorghum, the recommended dose of NPK was 75 kg N + 30 kg P2O5 + 30 kg K2O per hectare. Among varieties, at flag leaf, boot and 50 percent flowering stage, maximum plant height and LAI were recorded in CSV 53F which was at par with HJ 541. The GFY of CSV 53F was 2.2 and 32.9 per cent higher over HJ 541 and Duggi (local cultivar). Among different nutrient management treatments, maximum plant height, number of leaves per plant, LAI and dry matter accumulation/ plant were recorded with the application of 100% RDF + Vermicompost @ 5 t/ha (T7) which was at par with (100% RDF) T2, (125% RDN + 100% RDP + 100% RDK) T3 and (100% RDF + FYM @ 15 t/ha) T6 at flag leaf, boot and 50% flowering stage. The performance of these growth parameters was also reflected in the fodder yield (green and dry) of the single-cut forage sorghum varieties.
