A field experiment was conducted during Rabi season 2016-17 at Farm Research Centre, College of Forestry, SHUATS, Allahabad to calculate agro-meteorological indices of wheat crop under three date of sowing . 5th November, 15th November and 25th November and three variety . HD-2967, PBW-502, PBW-154. Wheat crop sown on 5th November utilised more thermal and heat units as compared to 15th November and 25th November sown crops. The shortening of the duration of the crop sown late was due to forced maturity because of higher temperature during reproductive phase of the crop. Similarly Hygrothermal Unit-I and II was found highest at 5th November followed by 15th November. The heat use efficiency and temperature use efficiency was found highest for HD-2967 variety and lowest for PBW-154 variety. | Agrometeorological indices requirement of wheat crop at Allahabad region under different sowing environment
