Agronomic Yields; all treatments and microplots
Agronomic yields from all the GLBRC treatments located on the Arlington and Kellogg Biological Station Intensive sites are presented here. Yield is given in multiple units including at standard moisture (grains only) and dry matter.
In addition to yield data from the main section of the plots, yield data from two microplot experiments is also presented here: corn stover removal microplots and nitrogen microplots. The microplots are generally on the west side of the main field and the control microplots are on the opposite side of the field. Also, residual corn stover (remaining biomass after machine harvest of stover) data is given.Corn stover (dried stalks and leaves remaining after grain harvest) is removed on the main field and in the stover microplot controls and was 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.
The nitrogen microplots were established on the perennial plots to look at the effects of fertilization on yield. Treatments G5, G6, G7, G9 are normally fertilized so the microplot was unfertilized and G10 does not receive fertilizer so the G10 microplot was fertilized.
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 GLBRC Agronomic Yields dataset. This data set contains information about agronomic yields for the GLBRC Biofuel Cropping System Experiment, the Stover Removal Experiment and the Unfertilized/fertilized Experiment at Kellogg Biological Station and Arlington and also for the GLBRC Scale-up experiment and Switchgrass N-rate experiments at KBS. Perennial treatments include herbaceous perennials- switchgrass, miscanthus, grass mix, old field and prairie (G5,G6, G7, G9 and G10) and poplar trees (G8) . Annual treatments include continuous corn (G1), and during 2008-2011 corn-soybean–canola rotations (G2-G4). In 2012 ,G2-G4 treatments no longer planted canola and added cover crops to a corn-soy rotation. Agronomic yields are measured during normal crop harvest by machine harvesters appropriate to each crop as described in the GLBRC Agronomic Protocol.
