Field day set for July 21 in Keiser

Pigweed management in cotton and soybeans will be showcased at field days held in Marvell on July 19 and at the Northeast Arkansas Research and Extension Center in Keiser on July 21.

"These two field days continue what was started at last November's Pigposium," said Bob Scott, extension weed scientist for the University of Arkansas Division of Agriculture. "Weed scientists are carrying that information to the field and give farmers an opportunity to see these practices in action."

The demonstrations and research plots "suffered the same too wet, too dry, too windy Mother Nature maladies that everyone has had to deal with this spring," he said. "Although this has created some challenges in managing pigweed, this is not all bad. This has allowed us to separate the weaker practices from the more reliable management techniques."

Both field days will start with registration at 8:30 a.m., with field tours leaving at 9 a.m.

The research will be discussed July 19 at "Fieldposium" held at the Curtis Story farm in Marvell. The event runs until lunch time and includes talks from University of Arkansas Division of Agriculture experts:

-- Liberty Link cotton -- Jason Norsworthy, associate professor, crop, soil and environmental sciences

-- Roundup Ready cotton -- Ken Smith, extension weed scientist

-- Pigweed control in soybeans -- Bob Scott, extension weed scientist

-- Soybean seed treatment -- Gus Lorenz, extension entomologist

There is no cost to attend. For more information, contact Smith at 870-460-1091, Scott at 501-676-3124 or Goodson at 870-338-8027.
