*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 5-13-01 @ 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
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 odds of at least 19 to 1. An
LSD designation of N.S. indicates a difference that is “non-significant”. COOPERATORS:
Roger Hybner (307) 737-2415, Alan Gray, Mike Killen, Rob Smith (307) 754-2223 (TablePAD01-03.doc) |
