Summary of Methods: The authors of this study tested the production and survival of chicory (Cichorium intybus) and plantain (Plantago lanceolata) cultivars under different summer grazing regimes to determine if any of these cultivars would have greater summer forage production than 'Pennlate' orchardgrass (Dactylis glomerata) in Pennsylvania pastures. After the first growing season several cultivars were removed from the study because they were not suited to the grazing regimes or the Pennsylvania climate, leaving only one plantain (Lancelot plantain) and one chicory (Puna chicory) cultivar to compare with 'Pennlate' orchardgrass. Frequent and severe grazing reduced the yield of all plant species when a timed rotational grazing system was used, but grazing did not impact plant production when grazing frequency was based on stubble height. Chicory and plantain had greater dry matter yields than 'Pennlate' orchardgrass when grazing management based on stubble heights was used, however, Puna chicory proved to be the better supplemental forage species because it's survival was greater than Lancelot plantain.

Annotation: A 150 mm stubble height remained in light grazing treatments and a 50 mm stubble height remained in severe grazing treatments. In the first part of the study pastures grazed frequently were allowed a 3 week rest period between grazing events and pastures grazed infrequently were allowed a 5 week rest period between grazing events. In the second part of the study the stubble height was allowed to recover to 250 mm following the last grazing event before grazing was applied to the pasture again.
