Comments: This was the 3 year of a three-year study using the same hybrids. This test was
also conducted at Bushland, Texas and Clovis, New Mexico during this time period. A protocol
was established during the first year for testing hybrids at all three sites. Collaborators for each
test site tried to meet the criteria established.

 Less than normal yields were attained at this test site. The season started with a full soil
moisture profile from a pre-plant irrigation that the protocol for the test called for. Seeds were
packaged to obtain a final plant population of approximately 26,000 plants/acre.

An excellent seedbed was available for the June 25 planting date. Seedling emergence was
rapid. The test received 2.7” of rainfall during the growing season. Air temperatures were warmer
than normal.

The test was hand harvested on November 11 and threshed with a stationary plot thresher. The
test mean was 1,564 lb/A. Fourteen hybrids produced grain yields greater than the test mean.
The test sustained no lodging. Bird damage averaging approximately 12% was observed on all
entries.
