Web application “Spatial IWR” developed by the Centre for Advanced Agricultural Science and Technology for Climate Smart Agriculture and Water Management (CAAST-CSAWM), Mahatma Phule Krishi Vidyapeeth (MPKV), Rahuri under ICAR-National Agricultural Higher Education Programme (NAHEP), New Delhi estimates the location specific real time irrigation water requirement of several field and vegetable crops; and orchard plantations by surface, sprinkler and drip irrigation methods for pre-defined irrigation interval; and accordingly decides the time for which the pump is to be operated just by tapping any desired farm location on Google Map.

Fetching of weather data: Fetching of historical, current and 4 days forecasted location specific weather data (maximum temperature, minimum temperature, maximum relative humidity, minimum relative humidity, wind speed, sunshine hours, etc.) from the “Open weather (weather service provider)”.
Other input data: Location of farm, crop details (The crop coefficient values are estimated daily from the crop and crop growth stage specific information on crop coefficient generated in this project based on literature and experimentation), soil details and irrigation system details
Derived parameters: Location specific real time reference evapotranspiration (ETr) Further the accuracy of all the derived parameters depend on the accuracy of parameters from which they are derived, formulae and constants used.
Irrigation water requirement and time of application are estimated.
