The study was conducted to investigate the relationship among Boro, Aus and  Aman rice production with rainfall variation in Rangpur district of Bangladesh. In this study, rainfall and rice production data (1990-2020) were used which gathered from Bangladesh Meteorological Department (BMD) and Bangladesh Agricultural Research Institute (BARI), Rangpur, Bangladesh Rice Research Institute (BRRI), Rangpur and Bangladesh Bureau of Statistics (BBS). To investigate the relationship into rainfall and rice production, linear regression method was employed. The findings of this research ensure that rainfall has had significant effects on rice production but these effects diverge among three rice crops. Rainfall has a statistically significant effect on Boro and Aus rice and unfavorable effects on Aman rice production due to modern agricultural practices, improvement of technologies, irrigation pattern and use of proper fertilizers.
