Rice is the staple food crop and it grows in three seasons in Bangladesh. The optimum transplanting time can satisfy its appropriate temperatures and solar radiation for vigorous vegetative growth and maximum grain yield. Recently, climate change affected the transplanting date of crops which recalls us to determine optimum transplanting date of rice in Bangladesh. To optimize the transplanting date in transplanting Aman (T. Aman) season, field experiment was conducted to evaluate the effect of different transplanting dates on yield and yield components of rice. Four transplanting dates (20th July, 4th August, 19th August and 3rd September) of two rice varieties including BR11 and BRRI dhan39 were used to design the experiment. Results revealed that seedlings transplanted on 4th August led to maximum grain yield. Also, they produced maximum number of productive (panicle bearing) tillers, number of grains per panicle, and 1000-grain weight. From this study, it can be concluded that farmers should transplant rice on 4th August at T. Aman season in Bangladesh for getting maximum benefit from their unit area.
