- 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).
