摘要：A field experiment was conducted during the growing seasons of 2016/17 and 2017/18 to investigate the effect of different sowing dates (Five sowing dates,i.e.,15th Oct.,1st Nov.,15th Nov.,1st Dec.and 15th Dec.) and three seeding rates of 108,156 and 204 kg/ha and their interaction on the yield and its component of wheat cultivar of Shandaweel1.Every sowing date was separated and seeding rate was randomly distributed in RCBD with four replications.The results reveal that effects of sowing date,seeding rate and interaction between sowing date and seeding rate were significant for most of the studied traits.Heading and maturity periods,plant height,yield,yield components and harvest index were significant affected by the differences of sowing dates.Early or late sowing (15th October or 15th December) significantly reduced plant height and days to heading and maturity numbers.Sowing in 15th November maximized yield and yield components of wheat Shandaweel1.Seeding rates effect was significant for all traits under investigation.Decreased seed rates (108 kg seed/ha.) increased number of days to heading and maturity.Meanwhile,the increased seed rate of 204 kg seed/ha.led to increase number of tillers/m2 and plant height.Seed rate 156 kg/ha produced the greatest yield and its components by sowing in 15th November with 156 kg seed/ha.
