Abstract: An experiment was conducted at Instructional Farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, West Bengal, India during rabi 2014-15 and 2015-16 to assess the performance of barley cultivars under different dates of sowing. The experiment was laid out in split plot design with three dates of sowing(November 19-23, December 1-3 and December 9-13) in main plots and six barley cultivars(HUB 113,K 603,K 409,K 551, K 560 and K 201) as sub-plot treatments with three replications. Delayed sowing significantly decreased the plant height, LAI, dry matter production, grain and straw yield. Maximum plant height, LAI, dry matter accumulation, crop growth rate, grain and straw yield and other yield attributes were recorded in 19-23 November sowing. Crop sown under November 19-23 recorded grain yield of 2.89 t ha-1, 17.95 and 46.70 per cent higher than the crop was sown under late (December 1-3) and very late (December 9-13) sown conditions, respectively. K 551 recorded higher tiller number as well as CGR value at all growth stages. Among the cultivars, K 551 was the highest yielder (3.21 t ha- 1) followed by K 409(2.97 t ha-1).
