*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 5-6-97@12lbs pure live seed per acre after 350 lbs/A of P₂0₅ were soil incorporated. Borders were seeded to Ladak. Trial was sprinkler irrigated. ELEVATION: 3745 ft above sea level; 150 days above 28 degrees F. SOIL TYPE: Silty Clay Loam. EXP. DESIGN: Randomized Complete Block, Four Replications. Yields differing from each other by more than the LSD are different at odds of at least 19 to 1. An LSD Designation of N.S. indicates a difference that is "non-significant". COOPERATORS: Roger Hybner (307) 737-2415 and Alan Gray (307) 754-2223. (PAD9799.wpd)
