Abstract:

In 1971 American sycamore (Platanus occidentalis L.) plantations were established on a terrace and a floodplain site along the Ohio River near Hawesville, Kentucky, to study short rotation yields. Three spacings--0.3 X 0.9 m, 0.9 X 0.9 m, and 1.8 X 0.9 m--and three fertilization treatments--control, N (169 kg/ha) and NP (169 kg/ha N and 112 kg/ha P)--were tested. After 3 years highest above-ground yields on both sites occurred with the closest spacing and N fertilization. Exclusive of foliage, saplings produced an average ovendry biomass of 14.3 and 15.4 metric tons per hectare (MT/ha) on the floodplain and terrace sites respectively for this treatment combination. Foliage accounted for approximately 20 percent of the total yield, and bark on the main bole comprised about 10 percent of the bole and branch dry weights. Branches, with leaves removed, comprised an additional 25 percent of the dry weights, leaving approximately 25 percent of the dry weight yield as bolewood. Forest Sci. 22:338-342.
