Dry Matter Yield — GLBRC Switchgrass Variety Experiment II
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Dry matter yields from machine harvests of the Switchgrass Variety Experiment II.
This datatable is part of the Switchgrass Variety Experiment II dataset.
This dataset contains data on the KBS GLBRC Switchgrass Variety Experiment II, established in May 2021, to examine the establishment potential, productivity, and feedstock quality of switchgrass varieties Nine different varieties (T1-T9) are planted in a complete randomized block design arranged in 4 replicate blocks (R1-R4). Plots are 9.2 × 12.2 m and are equally divided lengthwise into nitrogen-fertilized (+N) and unfertilized (0N) split-plots. Varieties include three upland (Blackwell, Cave-in-Rock, and Summer), three lowland (Alamo, Kanlow, and Cedar Creek (planted in 2022)), one coastal (Timber), and two hybrid (Liberty (crossed upland-lowland), and Shawnee (modified upland)) ecotypes.
