| *Bushel
yield based on 38 lbs/bushel and 12% moisture. **Date 50% of the plants headed; days after June 1. Site Information: Location: Tom Myers Farm, 11 North & 4 East Planting Date: April 6, 1998 Harvest Date: August 31, 1998 Previous Crop: potatoes Fertilizer: Nitrogen @ 11 lbs. acre~1; Phosphorus @ 52 lbs. acre~1 Seeding Rate: @ 100 lbs. acre~1 Soil Type: sandy loam Irrigation: center pivot Note: Lodging is usually a problem; however, no lodging this year may have made for very high yields. Harvest was unusually early; usually it is in September. Several experimental lines from USDA-ARS, Aberdeen, Idaho, look promising. Powell is a new release from ARS-Aberdeen and looks to perform really well here. Contact: Merlin A.

for moisture (all varieties <10% moisture at harvest) **50% of the plants headed Site Information: Planting Date: May 4, 1998 Seeding Rate: @ 90 lbs. acre~1 Threshing Date: August 31, 1998 Soil Type: Wetherill silty clay loam Fertilizer: Nitrogen @ 120 lbs. acre~1 + Phosphorus @ 40 lbs. acre~1 (urea + 11-52-0) broadcast on April 21, 1998 Herbicide: Harmony Extra @ 1/2 oz. acre~1 + 2,4-D amine @ 4 oz. acre~1 on June 18, 1998 Insecticide: Lorsban @ 1 pt. acre~1 on June 18, 1998 Precipitation: 3.0 inches (May 4 - August 25) Irrigation: 21 inches gross (7 sprinkler applications) Previous Crop: Dry beans (fall chisel plowed) Comments: The 1998 growing season was drier than normal, however, temperatures were not unusually hot (highest recorded temperature was 95 F with only six days above 90 F). The trial was sprayed for Russian wheat aphid on June 18. None of the entries lodged. Nebulas' seed is yellow colored with awns that are difficult to remove with our plot combine. Washford and Westford are hooded barleys grown for forage. Westford threshed easier than Washford, although Westford had some green sucker heads at harvest. Loose smut was noted in Washford. The hulless barleys are grown for niche markets. Contact: Dr. Abdel Berrada Colorado State University, Southwestern Colorado Research Center 16910 County Road Z, P.O.
