DAYTON SPRING BARLEY – 2005 WSU VARIETY TESTING DATA
- 2005 spring barley yields from the WSU Variety Testing nursery at the Dayton location averaged only 1896 lb/ac (yield losses were similar to spring wheat at this location, easily 60% less than the historical yield averages for Dayton, 4708 bu/ac). NOTE: the 2005 nursery was located approximately 15 miles NE of Dayton in the vicinity of Turner Elevator .
- This spring barley nursery was co-located with the spring wheat nursery (listed above) and plant growth and development responses to management and the environment were similar. Spring barley was more severely impacted indicated by an average test weight value of 39.0 lb/bu. That dramatically reflects the impact of the 2005 spring growing conditions.
- The nursery was on a re-crop piece of ground following winter wheat and seeded on 9 March 2005 into dry, cold seed bed conditions. Emergence was delayed until the end of March. There was 90#N, 10#P and 10#S of fertilizer applied for this crop. In mid-June 2005, soil moisture in the shallow root zone was depleted and the plants basically quit growing with pre-mature ripening. Low test weight values are indicative of the growing conditions for this crop. This is a nursery where 3-yr and 5-yr yield averages should be used to assess variety performance.
