Kansas Agricultural Experiment Station faculty members conduct research in nearly all areas of agricultural production. This online collection of research reports publishes preliminary results of research conducted at centers around the state in beef and dairy cattle, swine, meat science, plant pathology, sorghum and wheat breeding, cropping systems, irrigation engineering, cover crops, weed science, entomology, range management, turfgrass, and other areas. Research is supported by federal and state funds, grants, and Kansas State University.
