An experiment was conducted during the Kharif season of 2021 and 2022 at Krishi Vigyan Kendra, Bikaner-II (Lunkaransar), Swami Keshwanand Rajasthan Agricultural University, Bikaner, with the treatment combination of three Row spacing (30x15 cm, 45x15 cm and 60x15 cm) and seven hybrids of pearl millet (HHB-67 improved, HHB-197, HHB-299, MPMH-17, HHB-273, HHB-226 and BHB-1602). Three replications were incorporated in the split plot design of the experiment. The pooled result reveled that yield attribute, yield, Net returns and B:C Ratio were recorded significantly higher in the wider spacing (60x15 cm) statistically showed maximum seed yield (24.08 q ha-1), Net Returns (36324 Rs ha-1) with B:C ratio (3.07) followed by 45x15 cm space sowing seed yield (22.51q ha-1), Net Returns (33856 Rs ha-1) with B:C ratio (2.93) and third sowing spacing (30x15 cm) seed yield (19.19 q ha-1), Net Returns (27086 Rs ha-1) with B:C ratio (2.55) respectively. Similarly, hybridMPMH-17 recorded significantly higher grain yield 25.02 q ha-1 followed by hybrid HHB-299 (23.95 q ha-1), HHB-273 (22.23q ha-1), HHB-197 (22.07q ha-1), HHB-67 imp (20.84q ha-1), HHB-226 (19.76q ha-1) and BHB-1602 (19.61q ha-1) respectively. The highest seed yield 26.59q ha-1and Net Returns (42462 Rs ha-1) was recorded in hybrid MPMH-17 on sowing at 45x15 cm, which was statistically at par with hybrid HHB-299 sowing at same spacing.
