Peanut maturity groups

Arachis hypogaea L.

For peanuts, the concept of a maturity group is defined by the length of the growing season in days and the cultivar type, while the precise determination of harvest readiness is conducted using the hull-scrape method to evaluate the mesocarp color.

In the reference 10 varieties crop Peanut, where this is mentioned in the description.

Peanut classification by maturity includes early-maturing varieties with a growing season of 110–130 days, medium-maturing — 133–139 days, medium-late — 140–145 days, and late-maturing — 146–155 days or more. Spanish and Valencia market types are characterized by shorter growing seasons compared to Runner and Virginia types.

Due to the indeterminate growth habit of peanuts, calendar dates serve only as a guideline. The primary agronomic method for determining maturity is the Hull-Scrape method, which consists of evaluating the mesocarp color of the pods. The optimal time to begin harvest is considered to be when 70–75% of the pods reach the brown or black color category.
