Fifty Years of Research at NPRL

The Georgia Peanut Tour visited the National Peanut Research Laboratory in Dawson, Ga. This lab was established in 1965 for the purpose of improving farming practices. Since that time, scientists have studied a variety of factors involved in peanut production from better planting practices to better irrigation practices. Scientists have also researched ways to improve harvesting methods, storage methods, and the better use of environmental and financial resources.

Dr. Marshall Lamb, research leader and location coordinator at the National Peanut Research Laboratory, says, “We are one of the only USDA ARS labs that is solely dedicated to peanut research. Here at the lab we are developing technology for the end users.”

The NPRL has four different main projects that they work under. One of those is a cropping systems unit where we look at crop rotations and irrigation. Secondly, NPRL has an engineering unit that Dr. Chris Butts is the lead on where researchers look at ways to improve efficiency and quality in the post harvest sector. NPRL also focuses efforts on chemistry, genetics, and molecular biology where researchers are looking at natural defense mechanisms for peanuts but also ways to improve drought tolerance, and to come out with improved varieties for the industry.

NPRL will be celebrating their 50th anniversary this November. Through 50 years of research, scientists at the lab have created a tremendous amount of technology that is being used in the industry today. Originally, the focus at NPRL was on engineering and aflatoxins. However, over the years scientists have migrated to look at cropping systems type work and irrigation scheduling. Researchers at NPRL actually developed the Irrigator Pro scheduling system for managing the timing and amount of irrigation in peanuts. Researchers also developed Whole Farm which is a planning system that incorporates rotation data to help growers make better decisions on what to plant in the field for profit maximization.

Within the engineering unit at NPRL, Dr. Butts has done a lot of storage work both farmer stock storage and shelf stock storage. The research has actually changed the way the industry is looking at storing peanuts to maintain quality throughout storage. NPRL scientists are also looking at drought resistance projects with our cooperative breeding program with Auburn University. The program is showing a lot of promise with some of the cultivar lines that are showing drought resistance and will be available soon for farmers.

Dr. Renee Arias is working on ways to break the aflatoxin synthesis pathway and she has done an amazing amount of work on that area so that one day, we can hopefully eliminate aflatoxin contamination in peanuts. Her success has actually led to her receiving the Presidential Early Career Scientist of the Year Award a few years ago. Dr. Sobolev and Dr. Massa are working on looking at ways to increase phytoalexin production in peanuts which is a natural defense mechanism such that when a pathogen invades a peanut, it will be stronger and able to resist it better.

Adding Sulfur to Fungicides

The Georgia Peanut Tour attendees learned about the research conducted by University of Georgia Peanut Team members while touring the Southwest Georgia Research and Education Center in Plains, Georgia. Albert Culbreath, research plant pathologist at the University of Georgia Tifton campus, focuses his research on leaf spot diseases caused by a couple different fungi and tomato spotted wilt virus on peanuts. According to Culbreath, his research includes a variety of integrated management principles to try to take care of all those diseases as efficiently and economically as possible.

Culbreath coordinates research on resistant varieties and works with multiple breeding programs trying to develop better resistance to the tomato spotted wilt virus and leaf spot diseases. His research focuses on cultural practices and timing of planting that would affect both the leaf spot and the spotted wilt virus.

One of the things he spends a lot of time on especially with control of leaf spot diseases are fungicides. He says farmers are heavily dependent on fungicides for leaf spot control in peanuts. There are severe problems with resistance to about three classes of available fungicides. Through Culbreath’s research, he looks at different mixtures, timing, alterations and such that will give farmers the best performance of the fungicides that they have to use. That’s one of Culbreath’s main objectives for his work at the Southwest Georgia Research and Education Center in Plains, Georgia. He found a couple years ago that adding sulfur to several of the triazole fungicides that we depended upon and then last year adding sulfur to the Strobilurins fungicides greatly improves the efficiency with them even though we have resistance to those classes of fungicides.

Sulfur is a relatively safe and inexpensive addition and he has seen dramatic improvements in leaf spot control with that. So, in his tests in Plains this year, he is looking at different formulations of sulfur in combination with different fungicides that alone we don’t expect them to do that well. Through his research, he will see if adding sulfur to the fungicides helps to improve the control that we get from those fungicides.

Overview of Seeding Rate Research

The Georgia Peanut Tour attendees learned about the research conducted by University of Georgia Peanut Team members while touring the Southwest Georgia Research and Education Center in Plains, Georgia. Scott Tubbs, UGA cropping systems agronomist, discussed some of his research projects focusing on seeding rates when planting. Most of his work focuses on peanut agronomic research, but he also does additional work in cropping systems related to rotations that are built around peanuts and other major crops that are grown in our systems.

He conducts research at multiple locations throughout the state so that the research is representative of all growing areas across the state. Research is conducted at the University of Georgia Southwest Research and Education Center in Plains, the  Southeast Research and Education Center in Midville, the Attapulgus Research and Education Center in the Southwest corner of Georgia and the UGA Tifton Campus. So his research covers the entire state, lots of different soil and climate types to test our trials in multiple different soils and different weather pattern conditions.

The research trial he is conducting at the Plains Research and Education Center is a grow pattern and seeding rate treatment effect on six different cultivars of peanuts. He is testing six different varieties that were bred in four different programs from our public breeding institutions which include: University of Georgia, Auburn University, University of Florida, and the USDA ARS Breeding Programs. This trial is looking at twin row versus single row peanut using three different seeding rates of 5, 6 and 7 seed per foot for each one of those varieties.

In years past, he has conducted some similar research and noticed that the twin row row pattern will support a slightly higher seeding rate than the single row row pattern for maximizing yield potential. Results have shown that farmers can sometimes actually reduce their seeding rate a little bit lower in single row without losing yield potential. However, farmers may run into potentially some tomato spotted wilt virus interactions by reducing seeding rate at certain times of the year with certain varieties that are more susceptible to that virus.

Growing Peanuts for the Organic Market

Tour attendees visited the farm of Sedrick Rowe in Americus, Georgia, to learn more about organic peanut production. Rowe is a first-generation farmer who started growing organic peanuts two years ago. He is currently growing 12 acres of organic peanuts in Americus and 12 acres of organic peanuts in Dougherty County, Georgia. He grows corn for his rotation crop and grows rye and wheat for a cover crop. Rowe planted the peanut variety Georgia-12Y this year. He currently markets his peanuts through a combined effort with other organic growers through the Georgia Organic Peanut Association. Some of the organic peanuts are sold to Georgia Grinders Peanut Butter.

Rowe says the main issues he has faced with growing organic peanuts is weed control with the limited amount of chemicals he can use. Attendees on the tour were able to view Rowe’s field and see some of the morningglory weed that Rowe had issues with this year. Rowe uses a Kubota M7060 tractor, a rolling cultivator to loosen the soil and help control weeds and weed wiper. He also hand pulls some of the weeds in the field. He also uses a two-row peanut digger at harvest. This year he is purchasing a peanut combine from Ag Pro in Blakely to harvest his peanuts.

Founded in 2019, the Georgia Organic Peanut Association (GOPA) is a farmer-owned cooperative incorporated in the state of Georgia to market USDA Certified Organic peanuts and other agricultural products. The cooperative’s small farmers come from across the state and have almost 50 years of combined experience growing organic crops. The organization is committed to bringing added value to established farming operations and to creating new opportunities for small and beginning producers in the region.

Organic peanuts in Georgia are sold through a combined partnership to Georgia Grinders.

2019 Georgia Peanut Crop Update

The Georgia Peanut Tour kicked off with a Hot Topics Seminar on Tuesday, Sept. 17 at Lake Blackshear Golf Resort in Cordele. During the seminar Scott, Monfort, University of Georgia Extension Peanut Agronomist. According to Monfort the 2019 peanut crop pretty much the same as most years but the weather is not what you would consider a normal
year. Georgia growers planted approximately 650,000 acres of peanuts in 2019. At the beginning of the season, farmers started out in a good situation where they had plenty of moisture and heat to get the peanuts planted earlier than the last couple of
years. Then the weather changed and farmers ran out of moisture real quick and the weather turned hot. The temperatures soared to 90+ degrees and the middle to latter part of May all the way through today. We’ve had a tremendous amount of 90 degree temperatures all the way through the growing season this year with a limited amount of moisture. We did get moisture but it was pretty limited for the most part.

So when you start to look at the crop this year, there’s several things participants will notice on the tour. The irrigated peanuts which are about 50% of our peanuts look above average, because again they had the heat to push the crop but they also had the moisture. You can put on the moisture at any given moment during that period. Where we have problems that we are worried about right now is the non-irrigated crop and in any given year, we talk about how Mother Nature can throw a curve ball at us, in pockets or regions of Georgia but this year its all over. There have been some areas that received moisture at the right times and so there are some non irrigated crops that look just as good as irrigated crops. But, when you look at the average of non irrigated crop, it’s going to be below what we typically like to see yield and quality wise.

Georgia farmers have had problems with tomato spotted wilt virus, as well as, lesser corn salt borers and diseases. We are dealing with that and that’s going to cause some problems but overall the hot dry conditions is the major issue that we are dealing with.

Farmers are in the harvest season right now, it is the second week of September. We have been digging and harvesting peanuts for approximately a week a half now. Some of those are because we planted earlier, and we were able to mature those out and needed to come out of the ground to be harvested. A lot of those especially the irrigated crop looks pretty good. They are yielding very well as well as grading well – the quality is good at this time. As far as the non irrigated crop, farmers were able to save some of that crop by digging early because it did not put on any more peanuts beyond a certain period. So, they are digging those peanuts as well.

Growing the Organic Peanut Market

2018_gpt_savannah_0407sAttendees on the Georgia Peanut Tour learned about challenges organic farmers face with producing peanuts at the farm of Al Clark. He started farming in 1979 and began transitioning to organic production in 2007. Today Clark grows approximately 276 acres of organic peanuts, corn and soybeans at Healthy Hollow Farms in Brooklet, Georgia.

In 2018, Clark planted 20 acres of peanuts in two varieties — including Georgia 06-G and the less popular Georgia 12Y, which has proved promising in an organic system due to a viney growth habit that enables it potentially to outcompete weeds and general disease tolerance. Clark sourced untreated seeds and used a garlic-based inoculant (a mixture of neem and BacPac) at planting time, noticing better germination and foliage development among 06-G plants where the rate of this inoculant was doubled. This early growth, commonly referred to as “plant stand,” is key for organic peanut plants to overcome weed and pest pressure.

Despite a good stand, Clark has continued to struggle with weeds this season. While it has been shown that organic peanuts can be grown successfully in Georgia, the single biggest challenge is weeds, which in the Deep South can be diverse and aggressive. Organic growers do not have effective herbicides in their toolbox, which means they must rely on timely mechanical cultivation to kill weeds before they can get a foothold. But with constant rains throughout 2018, Clark could not get into his fields he needed to cultivate.

2018_gpt_savannah_0426sHowever, in recent years, Clark has employed an electrifying new technique: a lightning weeder. A long journey to North Dakota resulted in this purchase, which uses electricity run across a conductive bar running horizontal to the ground, above the sprawling peanuts, to electrocute tall weeds in the field. Although not effective on grasses, for weeds such as the prolific pigweed with a center stalk and deep taproot, the lightning weeder has a chance to shine (or, to be more literal, flame).

The lightning weeder does not come without limitations: scarcity, cost, and the huge amounts of power it uses. And even with successful weed control, there are still obstacles in producing organic peanuts. There is a lack of high quality, untreated seed for growers, and a lack of marketing power for organic Georgia Grown peanuts due to the smaller acreage and lack of infrastructure. In a Certified Organic system, each step from harvest to handling to processing has to be certified through the National Organic Program. With the scale of peanut production and associated infrastructure in Georgia so large, and the acreage of organic production so small in comparison, there can be little economic benefit to going through the certification process for shellers in Georgia. And without organic shellers to maintain the certification of the peanuts, there is a lack of supply for the marketplace.

And this is where Georgia Organics plays a role. Through a combination of USDA and private grants, and a partnership with the Southeastern African American Farmers Organic Network, Georgia Organics has been working with farmers actively growing or interested in growing organic peanuts to share production best practices, develop marketplace connections, address issues of seed supply, and facilitate the growth of organic peanuts in the peanut capital of the world to meet the high demand for Georgia-Grown Certified Organic Peanut products.

Peanut Research at Southeast Georgia Research and Education Center

2018_gpt_savannah_0345sThe Southeast Georgia Research and Education Center lies in the upper Coastal Plain near Midville, Georgia. Just south of the fall line, the 719-acre center was established in 1952, when Burke County deeded the land to the University System Board of Regents.

Orien L. Brooks served as the first superintendent and remained so until his death in 1978. Charles Perry was the second superintendent and now Anthony Black holds the title.

Originally concentrating on chicken, beef cattle and dairy research, today the facility’s efforts are focused on row crop research. Peanuts, soybeans, alfalfa, corn, cotton, sorghum and potential biofuel crops are studied.

Variety testing, pest management strategies, fertilizer application rates, seeding rates and disease management research programs are also in place. The center is the only UGA research location where UGA scientists study cylindrocladium black rot, a fungal disease first found in 1965 on peanuts in southwest Georgia. Today, CBR plagues alfalfa, clover and soybean as well.

Four full-time employees maintain research projects for UGA College of Agricultural and Environmental Sciences researchers conducting research at Midville. During the 2018 Georgia Peanut Tour attendees were able to see the on-going research projects involving peanuts.
