Cotton Growth, Lint Yield, and Fiber Quality As Influenced By Seeding Rates Under Dryland and Irrigation in the Rolling Plains of Texas

Best Management Practices for newer cotton (Gossypium hirsutum L.) varieties have not been updated in the Rolling Plains of Texas; therefore, seeding rate of cotton variety was evaluated under irrigation and dryland condition. Cotton variety, Phytogen 333, was planted into 4 rows by 40-inch row spacing for at least 150 ft in length under irrigated and dryland conditions. Treatments included four seeding rates at 1.7, 3.4, 4.4, and 5.6 seeds ft^-1. The study was designed as a randomized complete block design with 4 replications. Cotton plants reached maturity earlier with higher seeding rates than lower seeding rates based on weekly measurements on node above white flower. Yield and fiber quality will be discussed in the poster.
