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.
