The method of curve fitting by the principle of the Least Square (L.S) method is a relevant and well-received method of trend analysis, especially to make a project for the future time. The Least Square (L.S) method helps to fit mathematical functions to a given data set. For this research, we accumulated data from the Yearbook of Agricultural Statistics of Bangladesh for the year 2007-08 to 2019-20 with the help of the Bangladesh Bureau of Statistics (BBS) website. We arranged the data according to the proposed method and graphically represented it. This research aimed to forecast the production of rice in Bangladesh with trend line analysis by the method of Least Square (L.S) for the years 2020-21 to 2024-25. As a result, we found an upward trend line for the production of rice in Bangladesh. Therefore the production will be maximum in the year 2024-25.
