Abstract
A simple quantitative method was developed to determine groundnut maturity. The method was based on the changing seed:shell wt. ratio during maturation of the fruit. The ratio or maturity index was determined for fresh as well as air-dried pods, and these ratios correlated well with a physiological maturity index. The relationship between arginine maturity index and the air-dried shell maturity index (DMI) was also determined, and the 2 indices were negatively correlated. The DMI values across 9 sowing and 8 harvesting dates over a 2-yr period showed that DMI could be applied to estimate av. seed maturity under field harvest conditions. The 2 groundnut cv. tested, Florigiant and Florunner, were found to differ in max. DMI values. It was also shown that seed wt. increased with maturity then decreased after full maturity.
