Abstract
Cotton (Gossypium hirsutum L.) is an important crop in Texas and the southern U.S. Improving management to sustainably increase productivity in rainfed cotton is a goal of cotton research. Fertilization with foliar potassium (K) could potentially improve cotton quality and growth, and skip-row arrangements can conserve resources and reduce drought stress, which is a problem particularly in rainfed cotton, by reducing the planted area. A recent study in Agrosystems, Geosciences & Environment tested the effects of both foliar K fertilization and row spacing on cotton yield, quality, and nutrient uptake from 2017 to 2020. Researchers at the USDA-ARS facility in Temple, TX set up a field experiment with full-row treatments, where all rows were planted, and skip-row treatments where every third row was skipped. They also tested foliar K, applying K (0, 5, and 10 kg ha–1) during the blooming stage at two-week intervals. Foliar K application had no effect on yield or quality while the skip-row treatment increased yield and quality in the driest year and had no effect in the wetter years. Skip-row configurations can be used to improve quality and yield and decrease production costs in rainfed cotton in drier climates.
