UW-REC (POWELL):    The experiment was located at the University of Wyoming Research and Extension Center in Powell, Wyoming during 2007.  The soil was  a Garland clay loam (fine, mixed, mesic; Typic Haplargid) and had a cropping history of: 2006, dry beans;  2005, small grains; and 2004, dry beans.  The soil was fertilized for a yield goal of 100 bushels of grain per acre.  Fertilizer was applied on 19 March, at the rate of 150 pounds N and 65 pounds P2O5, in the form of urea (46-0-0) and diammonium phosphate (11-52-0).  The soil in the study area was prepared for planting by fall plowing, roller harrowing and leveling.  On 16 April, 41 spring oat varieties were established in plots 7.3 by 20 feet using double disk openers set at a row spacing of 7 inches.  The seeding depth was 1.5 inches, and the seeding rate was 100 pounds of seed per acre.   Weeds were controlled by a post application of a tank mixture of bromoxynil and MCPA (Bronate) broadcast at 0.50 and 0.50 pounds active ingredient per acre on 16 May. Furrow irrigations were 20 May,  5 June, 21 June, 03 July, and 15 July.  Subplots, 5.33 by 8 feet, were harvested on 23 August, using a Wintersteiger plot combine.
