Abstract: The frequency and severity of potassium (K) deficiency symptoms in cotton on the highly productive clay soils in Texas have increased in recent years. Two locations with low to medium soil K levels were chosen for these trials. Four rates of injected liquid K and four rates of dry broadcast K were evaluated. Plant growth measurements, yield, and quality were recorded. Visual K deficiency symptoms were observed in the low rates of broadcast K. The injected K yields were significantly higher than the broadcast applications. Micronaire values increased with increasing injected K rates, while other fiber qualities were not impacted.
