Various timings and frequencies of simulated grazing were applied to little bluestem plants (Schizachyrium scoparium) over three years in order to determine the appropriate grazing management for this plant in the Sandhills of Nebraska. The effects of defoliation depended on year of treatment and precipitation, effects of defoliation generally being more apparent in dry years and in the second and third years of the study. Throughout the study grazing reduced tiller numbers, tiller weight, bud numbers, and dry matter yields of little bluestem plants, however, multiple defoliations in one season and late season clipping were most detrimental to plants. The authors recommend grazing little bluestem plants one time in June or July, and that if late season grazing is necessary it should not be repeated every year to allow for plant recovery.
