Fig. 5. Pasture and species harvest index (HI) over the 2.3 yr from a mixed pasture rotationally grazed with cow–calf pairs under tall or short grazing height regimes in State College, PA. In the tall and short grazing regimes, bluegrass was harvested at 5 and 3 cm, respectively; all other species were harvested at 7 and 5 cm, respectively. Letters indicate species with HIs that differed significantly among species at P < 0.05. Dandelion HI differed between grazing regimes at P < 0.01 and is indicated with ; HIs of all other species did not differ between grazing regimes.
