Abstract

The arginine maturity index (AMI) method of predicting maturity in peanuts was evaluated on Virginia type peanuts grown in the North Carolina-Virginia area. Analyses of data from a two year study showed statistical differences (P > .05) of AMI values for cultivars, location and digging dates. Official grade factors suggested maturity levels consistent with AMI maturity predictions. Maximum yields per acre were observed near minimum AMI values. Optimum yields and dollars per acre were observed primarily at AMI values of 100. However, no sufficiently definitive value was determined to be the recommended point for digging peanuts.

The AMI method was tested on commercial grades of shelled peanuts. Significant differences (P > .05) between AMI values of cultivars were also observed.
