Checking Peanut Maturity

PeanutMaturity 001

We checked many peanut samples yesterday from all around the county. Peanuts are looking a lot better with rain. It rained more while we were sampling. Some parts of the county have had 7 inches in the last week and a half. We are having more reports of white mold, and seeing some pod rot as result. We need to observe vine strength. Most profiles are showing a 130-140 day maturity. Last year, 150 days was average. Looking at maturity last week, we noticed wider rangers. We normally start sampling at 120 days, however with more variability in maturity, UGA Extension Peanut Agronomist Dr. Scott Monford recommends evaluate fields that are 90 DAP or older. We are seeing a large variation of peanuts on the vine. Several fields have shut down around 105 DAP and are now coming loose in the hull. If the growers are not checking them until 135 DAP or more, they may indeed lose what they have.

Segregate Dryland Corners

With dryland maturity differences, one thing to consider is dryland areas of the field. Here is a note from Terrell County Ag Agent Nick McGhee:

Once harvest begins, growers need to consider segregating the peanuts they harvest in the dryland corners (or areas that received poor irrigation) from the peanuts that are harvested from irrigated areas. It does not take many poor quality pods to cause a load of peanuts to be graded as Seg 2 or worse. Growers need to consider separating these areas using a disk harrow and keeping them separate as they are loaded onto trailers. Do not let a few bad pods from a dryland corner affect the grade on an entire load of otherwise good quality peanuts.
