Effect of Potassium Application Timing on Cotton Fiber Quality and Yield

Potassium thiosulfate fertilizer was applied at varying application timings, which included a single preplant or side-dressed application and a split application with 40% applied at preplant and 60% applied at pinhead square. Parameters of two high-yielding cotton varieties to be evalauted will include leaf potassium concentrations, fiber quality, and yield.
