Planting has begun in the High Plains, but some producers have held out for precipitation. Adequate soil moisture is required for uniform germination. As the seed imbibes water, cell division and elongation occurs, resulting in the embryo rupturing the seed coat, and the seedling emerges. Once this process begins, it is important that it continues because plants are sensitive to desiccation at this time.
Some producers apply pre-plant irrigation to ensure adequate moisture. Others plant into dry soil conditions and “water up.”
Although this may be an option, there are potential negative consequences. Peanut seed will germinate under a wide range of temperatures, but a minimum average soil temperature of 65 degrees Fahrenheit at the 4-inch depth is advised, followed by a favorable forecast. Peanuts should crack the ground in seven to 14 days.
Frequent use of irrigation can reduce the soil temperature, slowing germination and emergence. These conditions favor the development of soilborne fungi that cause seedling disease. Peanut seedlings also can emerge from deeper planting depths.
However, the deeper planting depth increases the amount of time tender seedlings are exposed to disease fungi in the soil.
Plant roots develop rapidly, growing at a rate of 1 inch per day as long as soil moisture is adequate. Roots will not grow through dry soil, and failure to meet stored subsurface water will result in a shallow-rooted crop. This can be detrimental to achieving optimal yield and quality as water use increases with peak demand, approximately 1.5 to 2 inches per week, being required for flowering and pegging through pod development.
Significant yield loss can occur if rainfall is limited or irrigation capacity declines in the latter part of the season and adequate moisture isn’t available in the lower soil profile. Soil moisture is also important to ensure the survival of Rhizobia after planting, facilitate the movement of pegs into the soil and absorption of calcium during pod development. For more information about water requirements, contact your county Extension office.

Acreage And Disease Risk
The 2018 growing season is underway with planting as early as April 10 in South Georgia. Be mindful of the weather and moisture before planting. Planting into subpar conditions will only guarantee poor stands and/or the purchase and replanting of seed to get an adequate stand. This will cost more time and money compared to waiting until conditions are suitable initially.
Another key growers need to remember during planting is that peanut seed is a living organism, and storage can make a difference in maintaining the percentage germination and vigor over time. Peanut seed stored in a place that has extreme temperature swings, like an enclosed trailer, for an extended period can reduce seed quality and cause problems with stand establishment. Remember to plant seed in the order in which it was picked up from the peanut buying point (first in, first out).
During production meetings, someone asked, “Will the decrease in peanut acreage help with reducing potential disease?” The answer is, “Not in the short term.” It will take several years of acres below 700,000 before rotations will be corrected. With peanut rotations continuing to be stretched in some areas, many acres remain at a moderate to high risk for disease development.
Determine disease risk by evaluating your production practices using Peanut Disease Rx at the following link https://t.uga.edu/43C. This is an important step in determining how aggressive a grower needs to be in managing potential disease issues based on risk.
Growers with high-risk fields need to consider using a premium fungicide program to manage disease potential rather than a more basic fungicide program. Talk with your county agent regarding the different fungicide programs and how they might benefit you.

Early Weed Control Measures
May brings many early season management decisions. Making sure weeds are controlled is one of the most important. The majority of peanut in the V-C region are planted in conventional tillage systems, and it is always a good practice to incorporate some herbicide prior to planting. It takes time to incorporate herbicides uniformly, but this investment will be well worth the effort. At least some weed control will be obtained with incorporated herbicides even under dry conditions.
A DNA herbicide, one that contains pendimethalin or ethalfluralin, is a good start for control of pigweed, other broadleaf weeds and annual grasses – especially Texas millet, also called Texas panicum.
Chloroacetamide herbicides, which are products that contain metolachlor, acetochlor, or dimethenamid, can be incorporated, but make sure the rate matches the soil texture/organic matter content. For some growers, the time required to till and incorporate is simply not there.
For those in conservation tillage, the ability to incorporate is challenging. In these cases, apply residual herbicides, such as the chloroacetamide herbicides, at several timings early in the year. This increases the likelihood of catching a rain for activation.
Preplant, preemergence, at cracking and early postemergence timings, all within the first few weeks after peanut emergence, are good times to get herbicides with residual activity in the field.
A new chloroacetamide herbicide, Zidua, fits in the postemergence timing quite well. Of course, if some weeds are up, applying these herbicides with an appropriate contact herbicide, such as paraquat, is critical. The extra money spent early in the season on weed management will often pay for itself through protection of peanut from weed interference and by reducing the need for extra postemergence sprays later in the season.
As these applications are being made, it is generally OK to apply acephate to control thrips with these herbicides if systemic insecticides applied in the seed furrow did not perform well. Be careful not to apply paraquat if peanut injury from thrips is excessive. In most instances, if a systemic insecticide was applied in the seed furrow at planting, there will be enough protection from thrips to allow paraquat to be applied with no concern of excessive injury. But, if there is considerable thrips injury, applying paraquat will reduce yields.
From a resistance management standpoint, the herbicides I have focused on here have held up quite well in terms of evolved resistance in weeds. Although the DNA and chloroacetamide herbicides do not have significant post-emergence activity and paraquat (with Basagran) needs to be applied when weeds are small, these herbicides serve as good tools to reduce selection pressure on ALS inhibitors (imazapic and diclosulam) and PPO inhibitors (acifluorfen, flumioxazin, and lactofen).

Label Change In Alabama
Because of cool soil temperatures in April, planting is just now getting into full swing. Producers need to be aware of the label change for Strongarm use in Alabama peanuts.
Alabama received a Section 24(c) label for Strongarm in June 2017 for an over-the-top treatment. Before, it could only be used as a pre-emergence herbicide treatment. This will give you some herbicide options at planting for the 2018 crop.
The change is mainly because of tropical spiderwort (bengal day flower). If you have this weed in your field, I encourage you to use Valor behind the planter as a pre-emergence herbicide for pigweed and spiderwort control. Then you could use Gramoxone, Cobra or Ultra Blazer as a burndown spray for escaped weeds. At this time, you could add Strongarm for control of spiderwort, morningglory, bristly starbur and Florida beggarweed, and add Dual Magnum for spiderwort and pigweed residual control.
This will stretch out your residual herbicides for a longer period of protection against this troublesome weed.
I hope this will be helpful information to those of you who have this weed and may be unaware of the label changes with this herbicide.
FAQs
Soil Temperature, Planting Depth - Peanut Grower? ›
Recommended soil temperatures for peanut planting are 65 degrees Fahrenheit or above – measured at a 4-inch depth – for three consecutive days.
What temperature does the soil need to be for peanuts? ›Peanut seed will germinate under a wide range of temperatures, but a minimum average soil temperature of 65 degrees Fahrenheit at the 4-inch depth is advised, followed by a favorable forecast. Peanuts should crack the ground in seven to 14 days.
What is the planting depth for peanuts? ›The ideal time for planting peanuts is the first week of May when the soil is warm and moist. Germination is best between 68 and 95 °F. Plant seeds 2 to 3 inches deep in light textured sandy soils and 1½ to 2 inches deep in clay soils.
What are the optimal temperatures and planting depths for most seeds? ›Many factors affect seed germination, but the most challenging for gardeners and often least understood is soil temperature. While there is can be variation from one seed type to the next, most seeds for warm-season edibles prefer soil temperature between 70 and 80 degrees Fahrenheit (21.1 and 26.7 Celsius).
What is the ideal soil temperature for growing? ›The ideal or optimal soil temperature for planting and growing most vegetables is 65° to 75°F (18°-24°C).
What temperature do peanuts stop growing? ›However, once our nighttime temperatures drop to the lower 40's for three or more days our soil temperature will more than likely fall to 65 degrees or below. At this soil temperature, the plant will shut down and the peanuts will stop maturing.
What temperature can peanuts tolerate? ›Basics. Peanuts can withstand light frost in both the spring and fall, but production slows significantly if night temperatures reach below 60˚ F. Peanuts like warm weather and moisture.
What is the best climate to grow peanuts? ›Peanuts (Arachis hypogaea) are a compact plant in the legume family, native to South America. Grown globally as an agricultural crop as well as in home gardens, peanuts thrive in warm, humid subtropical regions with extended periods of heat. Peanuts grow well in the well-drained soils of the humid southern states.
How do you grow peanuts in a 5 gallon bucket? ›Once your pot is filled with potting soil or whatever mix you created, shell four peanuts and put them on top of the soil. Sow your seeds one inch deep, covering them with a thin layer of soil. Make sure you water deeply to help the seeds establish and start to germinate.
Do peanuts have shallow or deep roots? ›The ideal soil pH for growing peanuts is slightly acidic, between 5.8 and 6.2. The location should also be sheltered from strong winds, as peanut plants have shallow roots and can be easily uprooted.
What is the proper planting depth? ›
In general, seeds should be planted at a depth of two times the width, or diameter, of the seed. For example, if you have a seed that's about 1/16 inch thick, it should be planted about 1/8 inch deep.
What is optimal planting depth? ›This season, it is very important to control planting soil depth and seedbed. Good seed depth--1.5 to 2.0 inches or even deeper--is recommended in dry conditions to ensure good moisture availability for successful seed germination.
What is the appropriate depth seeds? ›In general, seeds should be planted at a depth twice their width, or diameter. For example, if you have a seed that is about 1/16 inch thick, plant it about 1/8 inch deep. Large bean seeds (up to 1/2 inch wide) can need to be planted an inch deep.
What happens if soil temperature is too high? ›Either too low or too high thermal degrees kill soil-dwelling organisms and plants. In particular, crops develop slowly at 90°F (32°C), while 140°F (60°C) is critical because bacteria in the ground can't survive the heat.
What temperature is too cold for seeds? ›For many garden plants in fact, a soil temperature below 50°F can be a problem. With temperatures in the 40s, seeds will readily absorb water, but not start to grow. This creates an opportunity for disease and rot, which can result in damping-off or poor growth.
Does soil temperature increase with depth? ›The annual temperature ranges for the various depths were 27° F. at 4 feet, 22° at 5 feet, 18° at 6 feet, 14° at 8 feet, 12° at 10 feet, and 9° at 12 feet. In the lower subsoil the temperature ranges per foot increase in depth were not of such great magnitude as in the upper subsoil.
Where do peanuts grow the best? ›In the United States, the major peanut producing states that grow 99% of the U. S. peanut crop: Georgia (which grows about 42% of all U. S. peanuts), followed by Texas, Alabama, Florida, North Carolina, South Carolina, Mississippi, Virginia, Oklahoma and New Mexico. These ten states are grouped into three regions.
Why is growing peanuts illegal? ›Is It Illegal to Grow Peanuts? In the United States, growing peanut plants in a home garden for personal consumption will not attract legal ramifications. However, commercial growers in states that require a license, like Georgia or Virginia, will need to purchase and sell their seeds to the letter of the law.
Do peanuts need a lot of water to grow? ›In comparison to other nuts, peanuts (yes, we know they aren't technically nuts) require the least amount of water to produce and have the smallest carbon footprint. For a one-ounce serving of shelled peanuts, it only requires 3.2 gallons to grow.
Do peanuts like hot weather? ›Peanuts are grown on about 42 million acres worldwide. They require temperatures of at least 56 degrees, with 86 degrees the optimal growing temperature.
What not to plant next to peanuts? ›
In-ground crops to avoid are onions and other members of the Allium family. Very tall crops, like pole beans and corn, should be avoided, as they will shade the peanut plants and can inhibit nut formation. Food crops such as cabbage and celery enjoy the same site conditions but are not so tall as to create shade.
What is the best fertilizer for peanuts? ›As a member of the legume family, peanuts have their own supply of nitrogen. For this reason, use 5-10-10 fertilizer, which contains less nitrogen than other commercial fertilizers.
What zones can you grow peanuts? ›Peanuts, scientifically known as Arachis hypogaea, are hardy in zones 6 to 11. They are in the legume family and classified as tropical plants. It is because of this that many people in cooler climates may wonder, “Can you grow peanuts in containers?”. Yes, but they do have certain requirements.
Can you grow peanuts in cold weather? ›Peanuts are not grown commercially in cold climates like yours because they require a long growing season: at least 100 days for the fastest cultivars and up to 150 days for commercially grown varieties. Thus, peanuts are mostly grown in tropical to warm temperate regions.
How many peanuts do you get from one plant? ›A single peanut plant can easily produce a bountiful harvest of 30-40 delicious nuts. The growing season for peanuts is from 130 to 160 days, which is why it is often considered a Southern crop.
How many peanut plants for one jar of peanut butter? ›Grow Your Own Peanut Butter
It takes about 540 peanuts to make a 12-ounce jar of peanut butter.
Peanut Quick Growing Tips
Peanuts require a long growing season, about 120 days of warm weather to mature. They can withstand light spring and fall frosts. Peanut yield: Grow 10 to 12 peanut plants per household member.
Planting. Once the land is tilled and ready, the farmer then plants the peanut seeds in rows normally 3′ apart, separating each seed by approximately 2″. An average of 120-130 pounds of seed are planted per acre.
Do peanuts like wet soil? ›Peanuts should be planted in warm, moist soils. Planting peanuts in cool, wet soils, or planting seed too deeply or too early, may result in slow seed germination and seedling emergence.
Do you soak peanuts before planting? ›For fastest germination, remove the individual peanuts (actually, the seeds) from the shells and soak them overnight before planting.
Do you shell peanuts before planting? ›
To grow peanuts, you will actually need to start with fresh, raw, uncooked peanuts still in their shells. To start inside, fill a large, four-inch-deep plastic bowl 2/3 full of moist potting soil. Shell four peanuts and place them on top of the soil; then cover with one inch of soil. Plants will sprout quickly.
What happens if you plant too deep? ›Planting too deeply
Deep planting causes bark deterioration at the soil line, which can eventually kill the plant.
Planting Depth
The shallowest planting is on top of moist ground with no soil covering it, and the deepest is generally no more than an inch. This information may be presented in the form of a fraction, like “1/4 inch.” Use your judgment, as it's better to plant too shallowly than too deeply.
Planting too shallow may result in poor germination due to low soil moisture retention near the soil surface or seed injury due to insects or disease. Similarly, if placement is too deep, seed may have delayed germination due to lower soil temperatures or result in poor germination or seed injury.
What is the most effective root zone depth? ›Effective root zone is the depth within which most crop roots are concentrated, which was estimated as ∼50–100 cm for wheat, maize, barley and canola, as ∼60–70 cm for peas, as ∼120 cm for alfalfa (ARD, 2013).
Will plants grow if planted too deep? ›Negative effects from planting too deep
The most common symptom of deep planting is unthrifty trees. The shoots grow much slower than they should and the tree appears to "sit there" for years without growing.
Planting a seed too shallow can cause low germination or seedling death. Seeds that aren't tucked deep enough into the soil often dry out before they can sprout.
Why seeds should not be sown too deep? ›Seeds placed deep in the soil do not germinate because they are unable to get sufficient oxygen. So, the correct answer is 'Unable to get sufficient oxygen'.
What is the recommended planting depth for most small seeded forages? ›Most forage grasses and legumes are smaller seeded; thus they require a shallow depth between ¼” and ½”.
What climate do peanuts grow best? ›Peanuts (Arachis hypogaea) are a compact plant in the legume family, native to South America. Grown globally as an agricultural crop as well as in home gardens, peanuts thrive in warm, humid subtropical regions with extended periods of heat. Peanuts grow well in the well-drained soils of the humid southern states.
How do you prepare soil for peanuts? ›
The optimum soil pH for groundnut is 6.0 to 6.5, but a range of 5.5 to 7.0 is acceptable. Plough the land 2 to 3 times at optimum soil moisture to secure good surface tilth to a depth of 15 cm. Follow planking after each ploughing to conserve moisture.
Where do peanuts grow best? ›In the United States, the major peanut producing states that grow 99% of the U. S. peanut crop: Georgia (which grows about 42% of all U. S. peanuts), followed by Texas, Alabama, Florida, North Carolina, South Carolina, Mississippi, Virginia, Oklahoma and New Mexico. These ten states are grouped into three regions.
Can I grow peanuts in potting soil? ›To grow peanuts, you will actually need to start with fresh, raw, uncooked peanuts still in their shells. To start inside, fill a large, four-inch-deep plastic bowl 2/3 full of moist potting soil. Shell four peanuts and place them on top of the soil; then cover with one inch of soil. Plants will sprout quickly.
What fertilizer is best for peanuts? ›Peanuts respond best to residual fertilization that has been applied to the crop preceding peanuts; however, if the area to be planted has not been fertilized during the prior 12 months, then ahead of planting, apply 10 pounds 0-10-20 fertilizer per 1,000 square feet.
What fertilizer does peanuts need? ›GYPSOIL is one of the best, most economical sources of gypsum for peanuts. It is a very pure form of calcium sulfate, analyzed to deliver 22 percent calcium plus 16 percent sulfur. Large-seeded peanuts require plenty of soluble calcium for proper seed development.
Do peanuts need rich soil? ›Peanuts grow best in loose, well-drained soil rich in organic matter.
