2Standing crop losses occurred prior to harvest of third cutting due to 23-25 degree F temperatures and 3.5 inches of snow on September 22-23, 2000. *Dried for 48 hr at 60 degrees C. To convert dry tons per acre to hay at 12% moisture, multiply by 1.136. ESTABLISHMENT PROCEDURE: Seeded on 4-30-98 @ 24 lbs pure live seed per acre after 250 lbs/A of 11-52-0 were soil incorporated. Borders were seeded to Big Horn. 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: Lyle Bjornestad, Mike Killen, Alan Gray (307) 754-2223. (TablePOW98-01.wpd) | ||||||||||
