Research on conventional soybean varieties expands

The University of Arkansas System Division of Agriculture is expanding its research into conventional or non-GMO soybean varieties as growers eye them as a way to combat escalating production costs and slipping commodity prices.

Jeremy Ross, Extension soybean agronomist for the Division of Agriculture, said his trial plots are being seeded with nine conventional varieties, including four developed by the University of Arkansas System Division of Agriculture’s soybean breeder, Pengyin Chen: Ozark, UA5213C, UA5612 and UA5014C.

In addition to a couple of private company varieties, this year’s trial includes two other public varieties: Virginia Tech’s highly adaptable Hutcheson and University of Tennessee’s Ellis.

Ross began the trials last year at the request of the Arkansas Soybean Promotion Board. The first year’s trials were relatively small because of the scarcity of seed.

This year, he had enough seed for growth trials in five counties: Lafayette County in southwest Arkansas, White and Prairie counties near the center of the state, Clay County in northeastern Arkansas and Crittenden County on the Mississippi River. “This spreads us out across the state,” Ross said.

The interest in non-GMO varieties comes from the growers, who find they have some key advantages:

• The seed is cheaper, since there are no proprietary technology fees to pay. “A good Roundup Ready variety might cost $65 to $70 a bag, our conventional varieties are $30 to $35 a bag. So there’s a cost-savings up front,” Ross said.

• In some markets, there is a premium paid for non-GMO beans. “Depending on the time of year and how they’re used, farmers are getting 75 cents to $1.50 premium over Chicago Board of Trade prices.”

• “The biggest reason, in the last year or so, is the demand for non-GMO beans for the poultry industry. Some of the companies coming into northeast Arkansas are starting the demand for chickens raised with non-GMO feed,” Ross said.

• Then there’s the option to save seed to use for the next growing season. Farmers using non-conventional, privately bred varieties are forbidden from saving seed for their own use the next season.

The rise of herbicide-resistant weeds such as pigweed has also been a factor, said Prairie County Extension Staff Chair Brent Griffin.

“The resistance issue has really changed people’s mindset,” he said. “There are seven glyphosate-resistant weeds now and other weeds that are resistant to other herbicides.”

Griffin said farmers in his county who have been growing non-GMO soybean varieties are finding they perform just as well as the non-conventional ones.

“They’ve been able to use conventional weed control to control the resistant weeds and still make 55- to 60-bushel soybeans,” he said. With falling commodity prices and profit margins at the razor’s edge, “they’ve got their backs against the wall” and saving on the technology fees, plus getting a premium, make non-GMOs a good bet.

Griffin said of the non-GMO market, “Growers are watching it. It’s not a niche or specialty crop anymore. People are willing to spend the money for it.”

The growers pursuing non-GMOs most aggressively, whether soybean or corn, are those who have on-site storage. In addition to a premium for delivering after harvest, those growers who can harvest, dry and hold their grain for delivery when the poultry companies need it earn more.

This year’s trial varieties are clustered in maturity groups 4.9 and 5.6. “We tried to have varieties with similar maturity groups so growers did not have to go back in the field two or three times to harvest.”

“With this variety testing program, we are hoping to get more information on how these varieties will perform in field situations,” he said.

Ross said he expects his non-GMO trial to expand next year to 10 counties.
