Wheat is the most important grain crop worldwide based on acreage and is ranked second when it comes to the total production volume. Wheat is the second most important staple crop in India after rice. Because of its wider adaptability it is grown from temperate irrigated to dry and high rainfall areas and from warm humid to dry cold environment. Optimum date of sowing is an important parameter, which affect the growth and yield attributes of wheat among other cultivation practices. To find out optimum date of sowing for Six wheat variety HS 562, HD 2967, HD 3086, HI1544, MACS 6222 and WR 544 was done at four different dates viz. 5th November, 25th November, 15th December and 5th January with row spacing of 20 cm as per treatments at experimental farm of Regional Agricultural Research Station (RARS), Assam Agricultural University (AAU), Nagaon, Assam, India. From the experiment, it was found that number of days to attain physiological maturity, Av. plant height (cm), Stand Count/sq.m, Number of ear heads /sq. m, Number of grain/ear head, 1000 grains weight (g), grain yield as well as biomass yield was significantly influenced. The crop sown under late sown condition took a smaller number of days to attain maturity in comparison to the crop sown timely. Maximum reduction in grain yield and biomass yield was found for the crop sown after 25th November onwards. The decreasing of yield attributes of the all six entries of wheat probably because of high temperature at the reproductive stage during the crop growing season.
