Perennial crops are multi-year crops that – unlike annual crops – have a lifespan of more than one growing season, such as fruit trees (apples, avocados, and so on), wines/grapes, sugar cane, and so forth. After the harvest, they automatically grow back or don't need to be replanted each year.
In SAP Intelligent Agriculture, a perennial represents a data entity that helps to organize the growing lifecycle of perennial plants and relates to a specific location – one field with one area. The perennial stores and provides key information about the perennial plant growing status (planting date, age when planted, current age, and so on).
Seasonal aspects of a perennial plant growing cycle are stored in a crop zone. The perennial acts as a container for all crop zones related to a specific field and area.
