Agronomic Yield - Perennial Crops

Agronomic yield from the poplar trees and 5 herbaceous perennial crops (switchgrass, miscanthus, mixed grasses, old field and native prairie) of the GLBRC Biofuel Cropping System Experiment located on the GLBRC Biofuel Intensive site. Yield data for these treatments are given as dry matter.

Microplots were established on the perennial crop treatments to look at the affects of fertilization on yield. Treatments G5, G6, G7, G8, G9 are normally fertilized so microplots in this treatment are unfertilized; Treatment G10 does not receive fertilizer so the G10 microplot is fertilized.

This datatable is part of the KBS GLBRC Agronomic Yields dataset. Agronomic yield record for the KBS Great Lakes Biofuels Research Center (GLBRC) Intensive site and the GLBRC scale-up fields.
