*Dried for 48 hrs at 60 degrees C. To convert dry tons per acre to hay at 12% moisture, multiply by 1.136.

ESTABLISHMENT PROCEDURE: Seeded on 4-30-96 @ 24lbs pure live seed per acre after 250 lbs/A of 11-52-0 were soil incorporated. Borders were seeded to Ranger. Trial was sprinkler irrigated.

ELEVATION: 4596 ft above sea level; 143 days above 28 degrees F.

SOIL TYPE: Sandy

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: Dan Brown, Ron Cunningham, Alex Malcolm, Jerry Langbehn, Milt Green and Alan Gray (307) 754-2223.
