Abstract: To study the effect of sowing conditions on yield and yield attributes of different wheat varieties, an experiment was conducted at research farm of the Punjab Agricultural University Regional Research Station, Gurdaspur during the Rabi 2015-16 and 2016-17.The treatments were consisted of two sowing conditions i.e. normal sowing (November sowing) and late sowing (December sowing) as main plots and in sub plots, five varieties viz. Unnat PBW 343, PBW 621, WH 1105, HD 2967 and PBW 343 were randomized in three replications in split plot design. Statistical analysis of the data revealed that timely sowing recorded higher yield attributes, days to heading and physiological maturity, growing degree days, biological yield as well as grain yield compared to late sowing conditions. At heading stage, variety PBW 343 and variety Unnat PBW 343 recorded significantly higher GDD as compared to other varieties during 2015-16 and 2016-17, respectively while at maturity stage, the variety PBW 621 and variety HD 2967 remained superior in GDD consumption during 2016-17. Among varieties, Unnat PBW 343 was found to be the best variety to attain maximum yield under both sowing conditions in Northwestern plains of India.
