Farmers will tour research plots Aug. 3 and Aug. 9 at University of Arkansas Division of Agriculture experiment station locations at Rohwer and Stuttgart.

On Aug. 3, the Rohwer division of the Southeast Research and Extension Center will present research and recommendations for weed and insect control and improved varieties of cotton, rice, soybeans and wheat. Tours begin at 8:30 a.m. and 10 a.m.

Nilda Burgos, associate professor of crop, soil, and environmental sciences on the Fayetteville campus, will present the latest research on the potential for genes from herbicide-resistant rice varieties to cross into red rice. Herbicide-resistant varieties provide economical control of red rice — a weed species closely related to commercial rice.

On Aug. 9, the Rice Research and Extension Center near Stuttgart will have research plot tours from 7:30 a.m. to 10:30 a.m. and an indoor program from 10:45 a.m. to 11:45 a.m.

Topics will include rice milling quality, 2007 farm bill issues, economic outlook, and rice rental arrangements. Research results for rice and soybeans will be presented on variety testing and breeding, weed and insect control, soil fertility and draining by growth stage.

State Sen. Bobby Glover and Rep. Benny Petrus will be guest speakers at the indoor program.

Updates will be provided on rice, soybean, wheat, corn and grain sorghum research and promotion boards.
