*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 @ 12 lbs pure live seed per acre after 350 lbs/A of P2O2 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 a 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.
