*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 6-1-00 @ 24 lbs pure live seed per acre after 250 lbs/A
of 11-52-0 were soil incorporated. Trial was both sprinkler and border
flood-irrigated. ELEVATION:
4104 ft above sea level; 148 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 at odds of at least 19 to 1. An
LSD designation of N.S. indicates a difference that is “non-significant”. COOPERATORS:
Mike Lindquist, and Alan Gray (307) 754-2223. (TableTORR00-03.doc) |
