Abstract: An experiment was conducted to study the yield and yield components of various wheat cultivars as affected by different sowing dates. Statistical analysis of the data revealed that different date of sowing and varieties had a significant effect on days to maturity, 1000 grain weight, grains spike-1, grain yield, biological yield and harvest index. While plant height, days to maturity, grains-1, 1000 grain weight, grain yield and biological yield was significantly affected by interaction between different sowing dates and varieties. Mean value of the data revealed that plant height (106 cm), grains -1, 1000 grain weight (75.20 g), grain yield (3611.11 kg ha-1) and biological yield (10370.00 kg ha-1) was maximum in those plots which were sown on November 1st when compared with other sowing dates. Similarly variety tatara-96 recorded maximum plant height, grains-1, 1000 grain weight, grain yield and harvest index when compared with other varieties under study.
