Abstract:

Age 20 data from a designed experimental study installed on 24 plots at one location in the Lower Piedmont in Jones County, Georgia, were used to evaluate the effect of six silvicultural treatments on survival, growth, and yield of cutover site-prepared loblolly pine plantations in the Georgia Piedmont. The following silvicultural treatments were included in the study: (1) clearcut only, (2) clearcut with all residual trees greater than 1 inch dbh removed by chainsaw, (3) shear and chop, (4) shear, rootrake, burn, and disk, and (5) shear, rootrake, burn, disk, fertilize, and herbicide. Treatment significantly affected all tree and stand characteristics at age 20. The shear, rootrake, burn, disk, fertilize, and herbicide treatment ranked best in all categories with the exception of survival and basal area, which were highest for the shear, rootrake, burn, and disk treatment. The shear and chop treatment was not significantly lower than the most intensive treatment in any measured category. South. J. Appl. For. 28(1):35–40.
