- Individual Productivity Index (IPI) establishes probable yields (yield expected for each crop) based on each individual’s yield history. The impact of year to year variability is stabilized by comparing the individual yields to the area yields of similar soil types and risk areas.
- For most crops, probable yields are calculated using the IPI method (exceptions are crops that use an individual coverage method).
- IPI is crop-specific and uses a -year moving average. There is a two-year lag in the data used in the calculation (i.e. data from the to crop years are used in the IPI calculation).
- There must be at least acres of a crop for the production data to be used in an IPI calculation.
- Calculations are based on data reported by the producer on Harvested Production Reports and/or claims (excluding reseed claims).
