Rice crop support the food need of billions of peoples and thus up-to-date and early statistics of acreage is essentially needed. Current study is being taken up to map the rice acreage for whole Haryana state covering a total of 4421200 ha area. Sentinel-1 SAR data were used for the mapping of Rice crop. A total of 28% of the state geographical area was found under the Rice coverage with a mapping accuracy of 90% using Maximum Likelihood (MXL) classification algorithm. Though the acreage was found to be less as compared to the statistical report of the year 2019 an early forecasting and yield assessment is possible using the current approach especially in monsoon season.
