Evaluation of Cotton Yield, Quality, and Plant Growth Response to Soil-Applied Potassium

The frequency and severity of potassium (K+) deficiency symptoms on the highly productive clay soils in the Central Blacklands and Gulf Coast regions of Texas have increased in recent years. While continuous dry conditions have undoubtedly contributed to this consistent occurrence of deficient K+ symptoms, the frequency and widespread geographic nature of the K+ deficiencies in multiple row crops, specifically cotton, is a major concern to producers and scientists. The objectives of this study are the evaluation of potassium placement and rates on cotton growth, development, yield and quality.
