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.
