Comparison of Soil and Foliar Applied Potassium Fertilizer in Cotton

The main objective of this research was to determine the impact of pre-plant, in-furrow and foliar applied K fertilizer on cotton growth, yield, and quality. Evaluated under both low and high irrigation in Lamesa and New Deal, TX, treatments consisted of preplant applied liquid K fertilizer at varying rates, in-furrow applied K fertilizer, foliar K applied three times during the growing season, and the combination of in-furrow and foliar applications. Differences in lint yield and fiber quality between soil and foliar applied K treatments will be determined.
