REARDAN SPRING WHEAT – 2005 WSU VARIETY TESTING DATA 

  1. 2005 Spring Wheat data from the WSU Variety Testing nursery at the Reardan location averaged 38.4, 45.27, and 48.5 bu/ac for soft white spring, hard white spring and hard red spring wheat, respectively.  The 2005 spring wheat average yields were lower by 31.7%, 23.2% and 11.1% for soft white spring, hard white spring and hard red spring wheat, respectively, compared to the historical 3-year average.  This nursery was planted re-crop following a 2004 winter wheat crop.
  2. STRIPE RUST infections were present in this nursery and most notable were susceptible varieties such as Zak, Penawawa, Edwall, Fielder, Winsome and Scarlet that exhibited substantial yield and test weight reductions.
  3. Overall TEST WEIGHT values were low, probably influenced by late season dry soil conditions coupled with fairly shallow root distribution caused by seasonal May/June 2005 precipitation patterns that allowed roots to survive on surface moisture and limited development to deeper soil depths.  The shallow root development was most detrimental during grain fill when roots were sitting in dry soil.
  4. In general, variety YIELD RANKINGS were similar to 3-year historical yield rankings but it was apparent that stripe rust resistance is an important consideration in varietal selection for this area.
