India Corresponding author ABSTRACT The percentage of normal surplus and drought months are 27.78 16.67 and Keywords 62.78 respectively. The percentage of drought surplus and normal years are 13.33 13.34 and 73.33 respectively according to Standard Deviation sd . Water supply The analysis also revealed erratic distribution of precipitation during Rabi season Agriculture Hydropower thereby preventing the farmers to go for Rabi crops. Therefore the irrigation must generation be assured for sowing Rabi crops. The monthly maximum rainfall at different probability level was calculated by Gumbel s Distribution method. From the Article Info drought analysis it was observed that study area is drought prone at two stages Accepted firstly at the beginning of the season which can cause delay in transplantation and 10 February 2021 secondly at the beginning of the grain ripening stage which can drastically reduce Available Online the crop yield. The annual daily maximum .
