Determining Peanut Maturity

Here is some information UGA Extension Peanut Agronomist Dr. Scott Monfort put together on runner-type varieties grown in Georgia and Peanut FARM. The USDA Crop Acres Report is estimating Georgia producers have planted 800,000 acres of peanut. This is more than expected. With an expanded planting window, this will help growers manage the increased acreage at harvest but trying to keep track of maturity of these acres may prove to be daunting. One way growers can help track the maturity is through the UFL PeanutFarm Website. Based on research, 2500 aGDDs is near maturity for most medium maturing varieties. We want to start doing maturity checks in the 2350 to 2400 range.

RUNNER-TYPE VARITIES

Florida-07: This is a medium-to-late maturing peanut (150 days +)

FloRunTM ‘107’: This is a medium- maturing peanut (135 to 140 days).

Georgia-06G:   Georgia-06G is a medium maturing peanut (135 to 140 days).

Georgia-09B: Georgia 09-B is a medium maturing peanut (135 to 140 days).

Georgia-12Y: This is a medium-to-late maturing peanut (140 days +) — May not follow board perfectly.

Georgia-13M: This is a medium-to-late maturing peanut (140 days +) — May not follow board perfectly.

Tifguard:  Tifguard is a medium maturing peanut (135 to 140 days).

TUFRunnerTM ‘297’: This is a medium to medium-late maturing peanut (135-145 days)

TUFRunnerTM ‘511’:  This is a medium to medium-late maturing peanut (135-145 days)

TUFRunnerTM ‘727’: This is a medium to medium-late maturing peanut (135-150 days)

Peanut FARM – Field Agronomic Resource Manager

PeanutFARM is a group of tools aimed at helping growers manage peanut development and maturity by tracking adjusted growing degree days (aGDD). aGDD’s use upper and lower daily air temperatures, plus the amount of water the crop receives from rainfall and irrigation, to predict the development of the crop. In addition to tracking maturity, aGDD’s are used by PeanutFARM to help schedule irrigation through estimating crop canopy cover and daily water use. This daily water use is then modified using weather data – which can be automatically drawn from state networks or input for individual fields, depending on grower preference. As the grower develops their own profile, each field can be managed separately and processed by PeanutFARM to accurately predict the need for irrigation and optimum harvest time. The purpose of PeanutFARM is to provide the producer with tools to ease both in-season and harvest management decisions.

Below are the three fields I have registered in the PeanutFarm program.
