Agronomic Yields - Annual Crops
Agronomic yield from the 4 annual crop treatments (continuous corn, corn, wheat and canola rotations) of the GLBRC Biofuel Cropping System Experiment located on the KBS GLBRC Intensive sites. Yield is given at standard moisture for corn (15.5 %), soybean (13 %) and canola (8.5 %).
In addition to yield data from the main part of the field, yield data from stover microplots is also given here. Stover microplots are generally on the east and west side of the main field, one side is the control (same as the main field) and the other side is an alternate stover treatment. Stover is removed on the main field and the stover microplot controls and is not removed in the stover microplots. The stover microplot study was designed to provide experimental data on the impacts of stover removal in order to establish threshold levels of stover management.
Agronomic yields are measured during normal crop harvest by machine harvesters appropriate to each crop as described in the GLBRC Agronomic Protocol.
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.
