The Crop water stress index (CWSI) and water deficit index (WDI) of wheat crop were developed using canopy air temperature difference (Tc-Ta)and vapour pressure deficit for scheduling irrigation. These values were varied with the change in soil moisture content and indicated water stresses of crop, which coincided with the moisture sensitive growth stages of wheat crop. Study was conducted in the Kangsabati Irrigation command, India for irrigation scheduling and crop yield modelling using remote sensing and GIS. The crop coefficients of wheat crop were generated using remote...
