The study was carried out at block level in Saraikela-Kharsawan district of Jharkhand to compare various parameters of rainfall distribution to describe the annual, seasonal, monthly distribution along with rainfall trends and seasonal variability. The rainfall data of all blocks for a period of 17 years (2001-2017) were collected from the District Agricultural Office of Saraikela-Kharsawan on a daily basis and rainfall were analysed with software (Weather cock V.1). All the blocks showed increasing rainfall trends except Kharsawan block showing decreasing trend of -3.7 mm/year and -8.1 mm/year annual and seasonal. The monsoon seasons received maximum rain (85-89%) and only 11-15% received in the remaining seasons.
