PEANUT PLANTING TIME – More Recommendations from UGA
April 18, 2022
UGA recommends planting 6-8 seed per foot in order to achieve at least 4 uniform plants per foot of row. Planting more than 7 seed/ft on singles can increase seed rot. Remind them that when they purchase seed and take possession of the seed they must keep it in a cool, dry, well ventilated location until planting. Growers and Buying points need to make sure to adhere to the 1st in 1st out rule. And always, plant seed under optimal temperature and soil moisture conditions to ensure good stands are achieved. “UGA doesn’t recommend the use of in-furrow fertilizers for peanuts”. UGA research has shown a 20 - 40 % reduction of stands with the 2-3 gal/A rate of fertilizers applied in-furrow with the seed. There is also observed a delay in emergence of 3-5 days with rates between 0.5 and 1 gal/A. Growers need to understand the risks of using these types of products.

Soil Temperatures Still A Little Too Cold
The Oklahoma Mesonet map below for April 13 shows we are still a little cool for peanut planting. We would like to see a 3 day average of at least 65° F., Georgia recommends >68° F. We also need a favorable forecast for the days following planting - and the forecast for April 14 is for
'possible freezing temps in the low areas'. You can go to the 3-day soil temperature maps at mesonet.org.

Planting Time is Approaching - Some Thoughts on Using Inoculant
Peanuts grow in a symbiotic relationship with Rhizobium bacteria (also known as Bradyrhizobium). The rhizobia obtain nutrition from the peanut plant and the peanut plant gains usable nitrogen from the bacteria. Thus, a symbiotic relationship. There is plenty research to show that in order for your peanut crop to reach its yield potential inoculating with Rhizobium is necessary. Therefore, inoculants are the most important fertility decision you will make. There are several types of inoculants that I won't get into, but there are several things we can talk about.
Hot soil temperatures and dry soil conditions can kill inoculants. Always place soil inoculants into moist soil conditions.
Make sure your inoculant is for peanuts, not soybeans, alfalfa..etc.
Rhizobium inoculant is a live material. Recommended storage is between 40° and 77° F. Do not store it in a location where it can get too hot.
Liquid inoculants should not be used with chlorinated water.
Do not use liquid inoculant that has been stored overnight in the spray tank.
For twin-row equipment twice as much inoculant will be used per acre as these bacteria have limited soil mobility.
Make sure inoculants are placed in the seed furrow row.
Don't assume that there is plenty of Rhizobium bacteria available in a field that had peanuts the year before. Especially fields that are very sandy with low organic matter.
Check pesticide labels for compatibility with pesticides (also remember your contract has a list of pesticides that you cannot use)
High rates of fertilizer (especially nitrogen) placed in the seed row can reduce the amount of nodulation.
I put this information together with some of the Peanut Production Guides from Arkansas, Oklahoma and Texas. Any comments feel free to email me at: firstname.lastname@example.org

SOIL TEMPERATURES WARMING UPThe Mesonet 3-day average soil temperature at 4 inches is going up and the weather forecast is for warmer days ahead. Planting time is just around the corner. Be aware research has shown that germination percentages drop when planting below the 65° F. To follow soil temperatures on the Mesonet go to mesonet.org.
