Arginine maturity index, methanol extract, shellout, and seed-hull maturity index methods of determining peanut (Arachis hypogaea L.) maturity were compared. Peanuts from four planting dates in 1978 were used. The comparisons showed that some of the methods are affected by date of planting and environmental factors, such as drought stress. Under the conditions of this test, the seed-hull maturity index and shellout were the most consistent indicators of the optimum yield period in 1978.
