The results showed that varieties as well as sowing dates had significant effect on most of the growth and yield contributing characters except tillers. Wheat variety Imdad-2005 proved to be more promising variety as compared to W.R.I-11 and SKD-2 varieties; with a plant height of 100.31 cm and 94.57 cm and 92.02 cm, tillers plant-1, 6.11, 5.24 and 4.64, spike length, 10.37 cm, 9.92 and 9.44 cm, grain weight plant-1 27.50 g, 25.32 g and 23.72 g, maximum biological yield 10355.49, 10162.14 and 9423.41 kg ha-1 were recorded from SKD-2 followed by Imdad-2005 and W.R.I-11 wheat varieties, grain yield 6134.60, 5962.03 and 5892.36 kg ha-1 and seed index value 5.26 g, 5.20 g and 4.64 g respectively. As regards sowing dates 15thNovember followed by 1st November sowing produced significantly better results for the growth and yield contributing characters of wheat varieties. It was concluded that variety Imdad-2005 was superior in all the growth and yield contributing characters, followed by W.R.I-11 and SKD-2; while among sowing dates, 15th November was remained appropriately best sowing time for producing highest grain yield in all varieties respectively.
