AUTHORS:

 

John R. Gannaway, Lyndon Schoenhals, Anna Hall, and Valerie Morgan, Professor, Senior Research Associate, Graduate Student, and Technician


MATERIALS AND METHODS:

 

             Test:                               Cotton Variety

             Planting Date:                June 24

             Row Spacing:                40-in

             Planting Pattern:Solid

             Herbicide:                      Treflan @ 1.5 pt/A applied pre-plant

             Fertilizer:                       None

             Rainfall:                         April - September, 6.0 in.

             Insecticide:                    None

             Harvest Aids:                 None

             Harvest Date:                 November 24

             Freeze Date:                   November 28


RESULTS AND DISCUSSION:


The dryland variety test was not planted until June 24. Yields ranged from 284 lbs. Lint/A down to 69 lbs. Lint/A. The fiber quality was very good considering the late date of planting. The 2.5 in. rain received in July was what kept this crop growing.
