Over the years, peanut maturity estimations have been based largely on subjective measurements. This paper reports a 3‐yr study of an objective method based on the tight transmittance measurement of a methanolic extract of freshly‐dug peanut pods which is both rapid and simple in operation and adaptable for field use. Results in 1975, 1976 and 1977 showed that the light transmittance of the methanolic extract correlated with the age of peanuts and dollar return per acre. Data also indicated that solar radiation, particularly during the fist 75 days of growth, may affect peanut maturity.
