Abstract

Tall fescue (Festuca arundinacea Schreb. ‘Kentucky 31′) drilled into a pasture infested with broomsedge (Andropogon virginicus L.) and fertilized with N, P, and K, eliminated broomsedge after 4 years. In a second experiment, fertilization with N, P, and K increased the density of Kentucky bluegrass (Poa pratensis L.), and broomsedge was gradually reduced over a 5-year period. Fertilization with P and K caused the density of legumes and grass to increase and broomsedge was nearly eliminated after 5 years. In both experiments the old growth of broomsedge was mowed each winter and cattle were then able to graze the new growth of broomsedge. Grazing may have aided in the elimination of broomsedge.
