In this paper successive depletion of groundwater level with expansion of ground water irrigation in Barind Tract has been discussed from 1985 to 2015. Rajshahi is a city in western Bangladesh. It is located in the north-west part of the country and situated on the northern banks of the river Padma. After starting of groundwater irrigation in Bangladesh, it spread rapidly all over the country, and about 80% of agricultural land is now supplied irrigation from groundwater. This study was conducted to estimate the Consumptive use and Crop Irrigation Requirement for various crops like Amon(rice), Boro(rice), Wheat and Potato. Blaney-Criddle Method was used in this study. In this study, data was collected from the zonal office of Barind Multipurpose Development Authority (BMDA), Rajshahi and Bangladesh Meteorological Department, Meteorological complex, Green Road, Dhaka. From the data analysis, the maximum value of consumptive use is 27.88 cm in the month of April, 1989 and minimum value of consumptive use is 2.02 cm in the month of February, 2011. The maximum value of Crop Irrigation Requirement is 21.66 cm in 1987.
