Abstract: A series of field experiments were conducted on sandy loam soil at Cereal Crops Research Institute, Pirsabak (Nowshera) NWFP, to study the effect of sowing time, crop density and weed control on heading and maturity of bread wheat. The data revealed that planting dates viz., October 15, November 15 and December 15 had significant effects on days to heading and days to maturity. Maximum days to heading and days to maturity were observed in November 15 planting. Further data indicated that maximum days to heading and maturity were in planting density of 100 and 150 kg per hectare seeding which was statistically at par with 100 kg seeding per hectare for days to maturity only. The results further demonstrated significant difference between weed control methods for days to maturity only. Maximum days to heading and maturity were found in no weeding plots whereas minimum days to maturity were found in chemical weeding and hand weeding plots.
