Performance of newly released wheat varieties under late sown irrigated conditions

A field experiment entitled “Performance of newly released wheat varieties under late sown irrigated conditions” was conducted during Rabi 2024-25 at the Instructional-cum-Research Farm, Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur (C.G.). The treatment consisting of two dates of sowing as main plot viz., D₁ (6^th December) and D₂ (24^th December) with seven genotypes as sub plots viz., (V₁) CG1029 (c), (V₂) MP4010 (c), (V₃) GW556, (V₄) WSM138, (V₅) HI1634 (c), (V₆) DBW425, (V₇) HD2932 (c) were laid out in split plot design with three replications. 125 kg of seeds were used ha^-1 for the crop, spaced 20cm apart in rows. Results revealed that growth parameters such as plant height (cm), number of tillers m⁻², dry matter accumulation (g plant^-1), crop growth rate (g plant^-1 day^-1), and relative growth rate (g g^-1 day^-1), as well as yield-attributing traits including ear length (cm), grains ear head^-1, test weight, grain yield (q ha^-1), straw yield (q ha^-1) and harvest index (%) were recorded maximum under the sowing date D₁ (6^th December) and minimum value was recorded under sowing date of D₂ (24^th December). Amongst the genotypes (V₁) CG1029 (c) recorded maximum for most growth and yield attributing parameters which was significantly superior over (V₄) WSM138, (V₅) HI1634 (c), (V₆) DBW425, (V₇) HD2932 (c) and (V₂) MP4010 (c) but was at par with (V₃) GW556. The genotype (V₁) CG1029 (c) recorded the highest B:C ratio (2.33), net return (76210.28 ₹ ha^-1) and gross return (108875.28 ₹ ha^-1) and while the genotype (V₅) HI1634 (c) recorded the lowest B:C ratio (1.69), net return (55351.51 ₹ ha^-1) and gross return (88016.51 ₹ ha^-1). Cost of cultivation was found in same in all treatments.
