Southern Farmers Experiment With Growing Sesame

Sesame is gaining a foothold in parts of the southeast United States, where cotton has long been king, as farmers take advantage of its drought tolerance and a recently developed trait that lets them bring it in with typical ag equipment.

Thousands of acres from Arkansas to Florida and Georgia were planted in sesame this year — sometimes joining a rotation of cotton, soybeans and corn and at times spread in fields too far away from irrigation lines.

"It's just a tough plant" that endures through a variety of conditions, said Seth Towles, who has 160 acres of sesame growing in a field across a dirt road from his cotton crop.

The nation's traditional sesame-growing region is in Oklahoma and Texas west of Interstate 35. It yields between 350 pounds and 850 pounds per acre a year, according to Erick Scott, a territory agronomist for Texas-based Sesaco Corp., which promotes the crop and develops new strains. The problem is the area only gets 16 to 20 inches of precipitation per year.

"They get rain, but not at the right time," said Scott, from Memphis, Tennessee.

But in the southeast, where rainfall can exceed 50 inches annually, sesame flourishes.

The crop isn't likely to supplant cotton or other primary crops in the Southeast — 30,000 to 40,000 acres pales to the millions of acres holding cotton, beans, milo or corn, according to the University of Arkansas Cooperative Extension Service. It could, however, could fill out farms that haven't extended irrigation lines to every field, Scott said.

"It costs about $160 an acre to raise sesame," Towles said, walking in mud on the edge of his field after a summer soaker. That's compared to about $650 for cotton and $350 for soybeans in these parts. Matching his yield last year — 960 pounds per acre — at last year's price of around 42 cents per pound would bring him $400 per acre before expenses.

One problem with sesame seed pods is that they split open shortly after maturity and spill 50-80 seeds onto the ground — leading some linguists to debate whether this led to the password "open sesame" in the book "Ali Baba and the 40 Thieves."

So, over the last 10 years, Sesaco has introduced a number of plants with shatter-resistant pods, letting farmers leave sesame in the field while they bring in more weather-sensitive crops. Later, farmers can adjust their combines to strip sesame plants of the hardy pods, keeping the seeds whole to protect the oil inside.

David Hodges of Jonesboro grew sesame last year but his crop rotation didn't leave him any space for it this year. He predicts it won't be much more than a niche crop in Arkansas — and this year's cool, wet weather could chase farmers away.

"If there's a bad year, that may be the death of it. If it's successful, it may go forward," Hodges said. "It's good where there are a lot of wildlife areas, where they have bad deer pressure. Deer don't like it."
