*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 5-23-00 @ 24
lbs pure live seed per acre after 250 lbs/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 from each other by more than the LSD are
different odds of at least 19 to 1. An LSD designation of N.S. indicates a
difference that is “non-significant”. COOPERATORS:
