UW-SAREC (LINGLE):    The experiment was located at the University of Wyoming, Sustainable Agriculture Research and Extension Center in Lingle, Wyoming during 2007.   The soil was fertilized for a yield goal of 100 bushels of grain per acre.  Fertilizer was applied rate of 100 pounds N and 30 pounds P2O5 in the form of ammonium nitrate (34-0-0) and diammonium phosphate (11-52-0). Ten wheat varieties were established in plots 5 by 20 feet using double disk openers set at a row spacing of 9 inches on 21 March.  Weeds were controlled by a post application of bromoxynil and MCPA (Bronate Advanced) broadcast at 0.40, and 0.40 pounds active ingredient per acre.  Subplots, 5 by 15, were harvested on 31 July, using an Almaco plot combine.
