May 9, 2008--No impact on corn from delaying irrigation (Cherry Creek News)
Research from Pioneer Hi-Bred, a DuPont business, and Kansas State University shows corn growers can safely delay the first irrigation without having a negative impact on yield. A nine-year field study was conducted in northwestern Kansas to evaluate the effects of delaying the first irrigation on corn grain yield and its physiological components. Results from the Pioneer-commissioned study at K-State Northwest Research and Extension Center in Colby, Kan., confirmed the corn vegetative stage prior to tasseling is the least sensitive to water stress. "This type of research offers growers the ability to plan irrigation and use only the water needed - avoiding any unnecessary irrigation," says Freddie Lamm, research irrigation engineer for K- State Research and Extension.
