Abstract: The Soil Adjusted Vegetation Index (SAVI) shows the vegetation status. The remote sensing based bio-physical variable maps were used to estimate SAVI in Uben river catchment and command area of Gujarat state, India. Multi date satellite images of Landsat-8 for Rabi season, year 2018-19 were used in the ArcGIS 10.3 software to derive the Soil Adjusted Vegetation Index (SAVI). The maximum SAVI in the study area was 0.850 on February 19, 2019.The minimum SAVI in the study area was -0.491 on February 19, 2019.The average SAVI value ranged from 0.199 to 0.552 for wheat crop, 0.138 to 0.441 for coriander crop, 0.147 to 0.307 for cotton crop and 0.124 to 0.154 for waste land. In wheat and coriander crop SAVI increased up to 0.552 and 0.441 respectively from December 1, 2018 to January 18, 2019 and February 03, 2019 respectively and then after SAVI decreased. In cotton crop higher value of SAVI i.e. 0.307 was observed in December then after it was decreased due to harvesting of cotton crop. The SAVI value of waste land area shows nearly uniform trend.
