Abstract: A field experiment was conducted during kharif season 2018 entitled “Studies on accumulated thermal unit of rice (Oryza sativa L.) cultivarsunder varying crop growing environment.†in sandy loam soil of N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The experiment consisted of nine treatment combinations comprised of three transplanting dates viz. July 15th, July 25th and August 04th and three varieties viz., NDR-97, NDR-2064 and BPT-5204. Results reveal that different phenophases of rice markedly varied with only dates of transplanting but also different weather variables which ultimately create the different crop growing environment to harvest the yield accordingly. Accumulated thermal unit was recorded in crop growing environment on July 15th (2158.5 0C days) at all the phenophases followed by July 25th (2059.7 0C days) and August 04th (1934.5 0C days) transplanting while among the cultivars BPT-5204 (2223.5 0C days) was recorded maximum thermal unit due to occurrence of long duration variety.
