Summary of Methods: Authors evaluated the effects of continuous and rotational grazing systems at different stocking rates on standing crop dynamics of tallgrass prairie in north-central Oklahoma. Year and stocking rates interacted to affect all components of standing crop. Although the slopes of the linear relationship between stocking rate and standing crop differed by year, they were not clearly tied to weather or total herbage production that year. Grazing system did not interact with year or stocking rates, and there were no significant differences between systems in July. However, total standing crop was 19% higher in the rotational system in September, suggesting a cumulative effect over the season.

Annotation: The yearlings grazed the units from early April until late September. Cattle in the rotational units remained in a single herd and were moved between pastures every 3 to 7 days. Cattle in the continuous units were not moved during the grazing season. All units were burned April 1, 1990 and March 20, 1993. Herbage standing crop was measured in July and September by clipping the total standing crop at ground level.
