In a three year study (1980–1982) at the Georgia Coastal Plain Experiment Station, Tifton, Georgia, the full-season Florunner and the short-season Pronto cultivars were harvested at six 10-day intervals beginning 90 days after planting. For the 3-year average, peanut (Arachis hypogaea L.) plants from Florunner harvested at 110 and each succeeding 10-day growth period up to 140 days produced greater pod yields, sound-mature kernels, large and jumbo seed, and greater calculated market value than Pronto. However, seed market grade components and maturity indexes reflecting quality and maturity were impaired when peanuts were dug too early and varied among years and growth periods.
