WICHITA, Kan. (AP) - Representatives of flour milling and food companies in Nigeria will visit Kansas and three other states in June to view this year's winter wheat crop. The industry group Kansas Wheat said Thursday the trade team will travel June 2-12 through Kansas, Oklahoma, Colorado and Nebraska. Members of the team will talk to university researchers, tour grain facilities and visit farmers. They'll also survey the U.S. hard red and hard white winter wheat crops. The Nigerians will be in Manhattan June 6 and 7, with stops at the Kansas Wheat Innovation Center and the International Grains Program at Kansas State University. Kansas Wheat Commission marketing director Aaron Harries said in a release that investment in research by Kansas growers is reassuring to Nigerian buyers.
