22-151 ABSTRACT The main objective of this study was to evaluate the effectiveness and improved productivity of reduced tillage pasture renovation methods in the establishment of triple species pasture mixtures into an existing naturalized stand. Experimental treatments, 2 (low and high stocking rates) by 2 (frostand sod-seeding methods) factorial with an additional non-renovated pasture contro...

Effects of prescribed fires on the 1-year establishment of white oak seedlings were investigated on the Clemson Experimental Forest, South Carolina, USA. Three stands, each consisting of a burn and a control treatment of about 1 ha in size, were examined in the study. On each burn and control treatment, six to eight dominant white oak trees were randomly selected along the slope and four 2-m ra...
This paper investigates the spatial organization and dynamics of retail markets using establishment level data on entry, exit, and location choice in the retail alcoholic beverage industry. Establishments are classi ̄ed into two groups based on ̄rm a±liation: chain vs. stand-alone stores. Stand-alone stores are further broken down into two categories according to product lines o®ered: diversi ̄ed...
Long-term persistence and sustained biomass yields of alfalfa (Medicago sativa L.) stands are important to producers. Yield performance and persistence of intrasubspecific crosses between alfalfa subspecies sativa and falcata after the first post-establishment year are unknown. The objectives of this study were to measure biomass yields, persistence, and biomass yield stability in interand intr...
