Pioneer, KSU Research Shows No Negative Impact on Corn From Delaying Irrigation: Research provides early-season recommendations, irrigation management tips

摘要

Des Moines, Iowa (May 8, 2008)--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 innorthwestern 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 the 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.
