The effect of five years of summer grazing (June, July, or no grazing) followed by fall grazing at varied stocking rates (no grazing, 1.0, 2.0 or 3.0 AUM per hectare) on herbage production of warm-season and cool-season grasses on Nebraska Sandhills rangeland was examined at the Gudmundsen Sandhills Laboratory (42� 07� N; 101� 26� W). Light summer grazing (0.5 AUM/ha) occurred for 4 to 7 days in mid-June or mid-July, followed by fall grazing in mid-October. Vegetation sampling included estimations of residual herbage remaining at the end of October along with sampling of herbage production in mid-June and mid-August to determine effect of the grazing treatments.
