YIELD ESTIMATION OF PADDY CROP BASED ON SOIL ORGANIC CARBON LEVELS IN COMMAND AREA OF HANJIHALLI VILLAGE TANK USING REMOTE SENSING (RS) AND GIS

Field research was conducted during 2019 in command area of Hanjihalli village tank to access the yield of paddy crop using remote sensing (RS) and geographical information system (GIS).The experimental study area was divided into 63 grids and soil samples were collected from the precise location using Garmin 72H GPS device.The organic carbon (OC) content was analyzed by employing wet oxidation method and the samples were sorted into low, medium and high OC status.The samples of low, medium and high OC status grids were marked using Garmin 72H GPS device, the paddy samples were analyzed for yield and were arrived at conclusions.Grain yield of paddy was recorded significantly higher (8942 kg ha -1 ) in high organic carbon level compared to other organic carbon levels.The higher paddy grain yield was a result of higher yield attributes.
