Fig. 1. (a) Yield per plant, (b) leaf yield per plant, and (c) stem yield per plant of a three-cut harvest management schedule on spaced-planted big bluestem and switchgrass plants from populations developed by divergent selection for seedling tiller number and high shoot weight. The first, second, and third harvests were on 25 May, 13 July, and 1 Sept. 2000, respectively. Similar letters within a harvest and species indicate no significant difference at P > 0.05. Plant type BMT is big bluestem multiple tiller Cycle 2, BST is big bluestem single-tiller Cycle 2, SMT is switchgrass multiple-tiller Cycle 2, and SST is switchgrass single-tiller Cycle 2.
