Peanuts Have Done What They Will Do

Posted by romeethredge on November 1, 2013

Peanut harvest season went pretty quickly this year. Most of the peanuts are dug and many folks are through picking as well. There are a few fields around that aren’t yet dug and a few that need to be picked as well.  The cold weather we just had has effectively finished our season, however, as far as peanut maturity.  The general rule is if we have 3 nights in the low 40’s peanuts will shut down as far as maturing any more.

 If you look at the website, to see the data from our UGA Donalsonville weather station, located at the airport, you will see the lows we got down to on those days.

On last Thursday Oct 24 it was 41.9, Friday it was 46.5 , Saturday 37.6 and Sunday it was 41.3 for our low temperatures in Seminole County.

Here are some peanuts that are being dug after the cold temperatures.  The grower waited until the danger of hard cold had passed and there is none expected in the next few days. They’ve done what they will do this season so we might as well dig them.

If we have any fields left to be dug, we can be making plans to begin harvest now that the colder mornings have passed.

Be sure to NOT DIG the day before a morning in which the low temperature is low enough that there is a risk of frost or freezing.  Once we start approaching the 35-36 degree range, frost can occur, especially in low lying areas of a field where the colder air will be. Keep in mind, the recorded low temperature is measured at 5 feet above ground by the NWS. Cold air sinks, which means it could be a few degrees colder in low lying areas of fields.

UGA Extension Peanut Scientist John Beasley says that “Frost or freezing temperatures on freshly dug peanuts can cause freeze damage to the kernels, which in turn, can be graded as Seg 2 peanuts. Seg 2 peanuts are greatly devalued when graded ($132 per ton).”

When dug, peanuts have 40% or greater moisture. Two or three days in the dug windrow allows the moisture content to drop enough so that the seed separates from against the inside of the hull. This separation will alleviate the risk of freeze damage. High moisture content with a seed still in contact with the inside of the hull increases the risk of freeze damage.

Just do not dig peanuts within 24 hours of temperatures in the mid thirties or lower.
