MANHATTAN K-State Research and Extension has posted two new agriculture-related publications online that are available free to the public. The "2013 Kansas Performance Tests with Winter Wheat Varieties" publication provides the results of annual comparisons of new and currently-grown winter wheat varieties in major crop-producing areas of the state. The tests generate information designed to help Kansas growers select wheat varieties suited for their area and conditions. The publication was authored by Jane Lingenfelser, K-State assistant agronomist and performance test coordinator.

Another publication, "Wheat Variety Disease and Insect Rating 2013," provides information on wheat genetic resistance to diseases and insect pests, which is typically the most effective, economical, and environmentally sound method of control. The ratings represent the results of multiple field and greenhouse evaluations by public and private wheat researchers. The ratings can help producers select wheat varieties to plant and minimize the potential for yield losses. The publication was written by Erick De Wolf and William Bockus, both professors in Kansas State University's plant pathology department, and Jeff Whitworth, associate professor in K-State's entomology department.
