The continual release of high-yielding cultivars and the need to maximum agricultural productivity on less acreage requires research regarding cotton agronomic practices including fertility, irrigation, and cover crops. Studies were conducted from 2016 to 2018 to evaluate cotton response to K fertilizer applications in irrigated and rainfed environments on K-deficient soils, response to cover crop species with various termination timings, and cover crop effects on water infiltration and soil health in conventional tillage systems. On K deficient soils, cotton yields had a linear response to K fertilizer application rate in all studies. Foliar K applications were compared to granular applications and no benefits were observed. Cover crop species had less of an effect on cotton growth and yield than did termination timing but cover crops improved water infiltration and bulk density. Direct benefits to cotton are expected when cover crops are implemented over time.
