ESTABLISHMENT PROCEDURE: Seeded on 5-10-01 @ 24 lbs pure live seed per acre after 250 lbs/A of 11-52-0 were soil incorporated. Borders were seeded to Wrangler. Trial was gravity-flow, flood-irrigated. ELEVATION: 4365 ft above sea level; 155 days above 28 degrees F. SOIL TYPE: Clay Loam. EXP. DESIGN: Randomized Complete Block, Four Replications. Yields differing from each other by more than the LSD are different odds of at least 19 to 1. An LSD designation of N.S. indicates a difference that is "non-significant". COOPERATORS: Alan Gray, Mike Killen, Rob Smith (307) 754-2223. (TablePOW01-03.wpd) | |||||||||
