Dimension of Humidity in Various Rice Cropping Season at Rangpur District in Bangladesh

This research was intended to analyze the variation and trend of humidity pattern in the major cropping seasons like Aus, Aman and Boro season in Rangpur region of Bangladesh. Humidity data collected from the Bangladesh Meteorological Department (BMD) between 1990 and 2020 was utilized in this investigation. Analysis of linear trends was used to investigate the seasonal change in humidity. The investigation’s findings demonstrated that there were numerous abnormalities in the daily, monthly, and seasonal variations of humidity where annual humidity rising in the Aman and Aus season and falling in the Boro season that main reasons are unusual monsoon pattern and abnormalities of temperature. According to the research’s findings, there have been notable fluctuations in humidity during the Aus, Aman, and Boro seasons. Bangladesh’s rice-based agriculture may suffer because of these adjustments. Bangladesh’s climate-driven agricultural sector can benefit from the application of thresholding, regional and countrywide humidity analysis, and other environmental methodologies in combination with adaptation planning for sustainable agriculture.
