1Dried 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 5-10-01 @ 24 lb pure live seed per acre after 250 lb/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 by more than the LSD are different at odds of at least 19 to 1, but an LSD designation of N.S. indicates yield differences were not significant.

COOPERATORS: Alan Gray, Rob Smith, Brad May, Mike Killen(307) 754-2223.
