Agronomic Yield of Annual Crops; treatments 1 - 4
Agronomic yield from the 4 annual crop treatments. These treatments are part of the GLBRC Biofuel Cropping System Experiment located on the Arlington and 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. The 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 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. Starting in 2013, 1/3 of the stover microplot control was herbicided and the first yield was taken from these plots in 2014.
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.
