TITLE:
Results of the Dryland Cotton Variety Test at AG-CARES, Lamesa, TX, 2001.
AUTHORS:
John R. Gannaway, Lyndon Schoenhals, and Valerie Morgan, Professor, Senior Research Associate, Technician
MATERIALS AND METHODS:
Planting Date: June 1
Row Spacing: 40-in
Planting Pattern: Solid
Herbicide: Treflan @ 1.5 pt/A applied pre-plant
Fertilizer: None
Rainfall: April-September, 5.5 inches
Harvest Aids: Cyclone@ 16 oz/A on September 27
Harvest Date: December 3
Freeze Date: November 27
RESULTS AND DISCUSSION:
These yields were determined by hand harvesting the plots. This was done because the plant size was extremely small due to moisture stress. If these plots hand been machine harvested, the yields would have been somewhat lower. However, the relative ranking of these materials based on yield would have remained the same. The fiber properties were not influenced by hand harvesting.
