KBS129:Poplar (T5) Density Study
A microplot study was conducted in the Poplar (T5) treatment of the LTER Main Cropping System Experiment (MCSE; 1989-2008) to examine the effect of three planting densities on poplar yields over two harvest cycles: the first cycle (1989-1998) included split plots of +/- herbicide use within each microplot and the second (1998-2008) recorded the coppiced regrowth of harvested trees. Poplars were planted in 1989 at spacings of 1 × 0.5 m, 2 × 1 m, and 2 × 3 m, in 43 m wide (E-W) and 25 m long (N-S) microplots arranged in one and a half rows along the northern edge of each replicate plot (R1-R6). The main plot was planted at a spacing of 2 × 1 m.
