Fig. 1. Total nonstructural carbohydrate concentrations in response to tree species (HL = honey locust, BW = black walnut) and toe-, mid-, or shoulder- (Sho) slope position in Appalachian silvopastures harvested in May, June, and July in 2002 and 2003. Species effects (P < 0.05) were observed in May and July of 2002 and May and June of 2003. Slope tended (P < 0.10) to affect TNC in June of each year, and species x slope interaction (P < 0.05) was observed in June 2003.
