0PI 644818'PERFORMER'Panicum virgatum L. North Carolina, United StatesNLGRPNot Available2007DEVELOPED11/2006CultivarPerformer was selected for its improved nutritive value as estimated by in vitro dry matter disappearance. Consequently, it is not as tall a grower as some of the present lowland cultivars. However, emphasized were improved digestible nutrients produced per acre, a combination of yield and digestibility. Performer produced 7, 567 lb/ Ac of digestible nutrients with a dry matter digestibility of 56.5%. When offered to animals in separate experiments, they selected from Performer a diet that averaged 66.5% digestible. The consumed forage averaged 53.2 % large particles that were 65.6 % digestible, 33.0% medium particles that were 66.6 % digestible and 13.9% small particles that were 68.9% digestible. Performer consistently had the greatest digestibility among other cultivars included in the tests. It improved digestibility is attributed, in part, to its reduced lignin concentration which averaged 5.8% at the heads-emerging stage. Performer is well adapted across the Coastal plain and Piedmont regions. It is well liked by animals and can be used for either grazing or as a stored feed. Performer appears to have no obvious pests, although limited acreage does not generally carry the potential for high infections . 1717741PI 644818
