IFAS: Start Tracking Peanut Maturity Now with the Adjusted Growing Degree Day Tracker

If you are planting peanuts now, you will want to keep an eye open for how far along your peanuts are. You can use Days After Planting (DAP) to determine how mature your peanuts are, but another option is to use Adjusted Growing Degree Days (AGDD), which is based on temperature and accounts for year-to-year variations in the growing conditions of your crops. The UF/IFAS peanut team will be providing AGDD for a number of planting dates and locations so that peanut growers in Florida can track the maturity of their crop. You can read more about it at https://nwdistrict.ifas.ufl.edu/phag/2021/05/07/start-tracking-peanut-maturity-now-with-the-adjusted-growing-degree-day-tracker/. You can also use AgroClimate to provide some information for Florida and parts of Georgia by using their degree day tool at https://agroclimate.org/tools/growing-degree-days-calculator/. Unfortunately, they only offer base temperatures of 40, 50 and 60, which is not ideal for peanuts. If you are in Georgia, you can also do your own calculations based on the nearest UGA weather station by using our GDD tool at https://www.georgiaweather.net/?content=calculator&variable=dd&type=dt and picking the appropriate base temperature (I think peanuts is usually 56 F) and your planting date to determine the AGDD. According to IFAS, once you get close to 2500 AGDD, then it is time to watch your peanuts carefully for maturity using other methods.
