UW-REC (SHERIDAN):    The experiment was located at the University of Wyoming Research and Extension Center in Sheridan, Wyoming during 2007. The soil was a Wyarno clay loam (fine, montmorillonitic, mesic; Ustollic Haplargid), had a cropping history of: 2006, fallow; 2005, small grains; and 2004, fallow.  The soil in the study area was prepared for planting by fall chiseling, followed by spring chiseling and roller harrowing.  Ten oat varieties were established in plots 5 by 20 feet using double disk openers set at a row spacing of 8 inches on 24 April.  The seeding depth was 2.0 inches, and the seeding rate was 50 pounds of seed per acre.  The site is a dry land site with no irrigation.    Rainfall during the growing period (1 April-31 July) was 7.42 inches.  Subplots, 5 by 15 feet, were harvested on 07 August using a Wintersteiger plot combine.
