SUMMARY
The field experiment was conducted at Agronomy Research Area, CCS HAU, Hisar (India) during the summer season of 2020. The two factor experiment was laid out in randomized block design with three replication. The experiment consists 14 treatments formed by combination of two single-cut forage sorghum cultivars (HJ 541 & HJ 513) and seven different foliar spray involving S1: No spray (control) S2: water spray at 45-50 DAS, S3: water spray at 25-30 DAS & 45-50 DAS, S4: urea spray @ 2% at 45-50 DAS, S5: urea spray @ 2% at 25-30 DAS & 45-50 DAS, S6: NPK spray (18-18-18) @ 2% at 45-50 DAS, S7: NPK spray (18-18-18) @ 2% at 25-30 DAS & 45-50 DAS. Among the varieties, HJ 541 recorded highest green fodder yield (GFY), dry fodder yield (DFY), crude protein (CP) content and In-vitro dry matter digestibility (IVDMD) of 407.52 q/ha, 99.61 q/ha, 8.90% and 51.64, respectively. Among the foliar nutrition, significantly higher GFY, DFY, CP content and IVDMD of 433.33 q/ha, 111.51 q/ha, 9.27% and 52.40 %, respectively, were recorded with NPK spray (18-18-18) @ 2% at 25-30 DAS & 45-50 DAS. It is concluded that use of single-cut forage sorghum variety, HJ 541 and application of NPK spray (18-18-18) @ 2% at 25-30 DAS & 45-50 DAS was recommended for higher green & dry fodder yield and better quality.
