The experimental study for the research name entitled ‘‘Performance of new wheat varieties at different dates of sowing under irrigated conditions’’ was carried out at Instructional Farm of Barrister Thakur Chhedilal College of Agriculture and Research Station, Sarkanda, Bilaspur during Rabi 2021-22. The design was split plot with three replications. The treatment comprised of two dates of sowing in main plot viz, D₁ (13^th November) and D2 (3^rd December) with seven genotypes in subplot viz RCZTS 101, RCZTS 102, RCZTS 103, RCZTS 104, RCZTS 105, RCZTS 106 and RCZTS 107. 100 kilogram of seeds were used per hectare, spaced 20 cm between, to sow the crop. The experimental site had neutral soil (6.9), which had a clay loam texture. Potash (0.60 percent), low accessible nitrogen (138 kg ha^-1), medium phosphorus (12.8 kg ha-¹), and medium organic carbon (0.60 percent) were all present in the soil (186.14 kg ha^-1). For this experiment, a fertilizer dose of 120:60:40 NPK kg ha^-1 was advised. The outcome demonstrated that plant population, growth parameters, including plant height, dry matter accumulation (g plant^-1), number of tillers, and yield attributes, including ear length (cm), weight of grain ear-1 head, number of grain ear-1 head, grain yield (q ha^-1), test weight (g), straw yield (q ha^-1), and harvest index (percent), were recorded maximum under the sowing date of 13th November (D1) and minimum value was recorded under the sowing date of 3rd December (D2).Among the genotypes, maximum growth and yield attributing parameters viz. number of tillers (m^-2), dry matter production (g plant^-1), grain yield and straw yield were recorded maximum in genotype (V4) RCZTS 104 which was at par with (V5) RCZTS 105 followed by (V2) RCZTS 102, while the minimum was recorded in genotype (V3) RCZTS 103.The genotype (V4) RCZTS 104 recorded the highest B:C ratio (1.93), net return (58,175 ₹ ha^-1), and gross return (88,275 ₹ ha^-1), and while the genotype (V₃) RCZTS 103 recorded the lowest B:C ratio (1.45), net return (43,573 ₹ ha^-1) and gross return (73,673 ₹ ha^-1). Cost of cultivation was found same in all treatments.
