The present investigation entitled “Performance of wheat (Triticum aestivum L.) varieties under different dates of sowing in northern hill zone of Chhattisgarh” was carried out during Rabi of 2024-25 at Department of Agronomy under field, Raj Mohini Devi College of Agriculture and Research Station Ajirma, Ambikapur (C.G.). The experiment was conducted in split plot design with 03 replication 09 treatments were allocated in each replication. The treatment consisting of three varieties as main plot viz. V1-Kanishka, V2-Vidya and V3-Mavanti with three dates of sowing as sub plot viz. D1-30th November, D2-15th December and D3-30th December. 120:60:40 (NPK) kg of fertilizers was used per hectare for the crop, spaced 22.5 cm in rows.

Result showed that growth parameters, including plant stand (m-2), plant height (cm), number of tillers (m-2), dry matter accumulation (g plant-1), crop growth rate (g m-2 day-1), 50% ear head emergence and yield attributes, including effective tillers (m-2), number of ear plant-1,length of ear (cm), ear weight-1 (g), number of grains ear-1, 1000-grain weight (g), grain yield (45.13 q ha-1), straw yield (51.36 q ha-1), harvest index (48.40%), net return (₹ 85535 ha-1) and B:C ratio (2.72) were highest under variety Mavanti (V3) as compared to Vidya (V2) and Kanishka (V1).
Among the dates of sowing, maximum all growth parameters, plant stand (m-2), plant height (cm), number of tillers (m-2), dry matter accumulation (g plant-1), crop growth rate (g m-2 day-1), 50% ear head emergence and yield attributing characters viz. effective tillers (m-2), number of ear plant-1, length of ear (cm), ear weight-1 (g), number of grains ear-1, 1000-grain weight (g), grain yield (46.00 q ha-1), straw yield (51.58 q ha-1), harvest index (48.21%), net return (₹ 87637 ha-1), and B:C ratio (2.78) were highest crop sown on 30th November (D1) as compared to 15th December (D2) and 30th December (D3).
