1. A computerized method for managing irrigation of a crop in a field plot for a growing season, the method comprising:
receiving values of one or more forecast global independent variables (GIVs);
applying a global remote sensing product (RSP) model to the received values of the forecast GIVs and, responsive to the applied global RSP model, determining forecast global RSP values;
receiving values of forecast plot-specific independent variables (PSIVs) associated with the field plot;
applying a plot-specific RSP model to the received values of the forecast PSIVs and, responsive to the applied plot-specific RSP model, determining forecast plot-specific RSP values;
receiving a forecasted reference evapotranspiration (ET0) associated with the field plot; and
receiving one or more actual plot-specific RSP values associated with the field plot,
wherein, responsive to the forecast global RSP values, the forecast plot-specific RSP values, the forecast ET0 and the actual plot-specific RSP values, the method further comprises:
generating a first crop evapotranspiration (ETc) curve;
responsive to the generated first ETc curve, determining a growing season water amount for the field plot and/or determining a next irrigation water amount for the field plot; and
outputting to a device the determined growing season water amount and/or the determined next irrigation water amount such that irrigation of the field plot can be adjusted.
