Agronomic Yields of Annual Crops — GLBRC Biofuel Cropping System Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Agronomic yields from the main plot and subplots of BCSE annual crop treatments (G1-G4, depending on year). Yields are measured during normal crop harvest and are given at standard grain moisture for corn (15.5%), soybean (13%) and canola (8.5%), and as whole plant (6 inch cutting height) dry matter (0% moisture) for sorghum. Note that crops and management in G2-G4 have changed over the years; consult the KBS Aglog or archived plot maps for crops planted in a given year. For dry matter yields of grain crops, see datatable GLBRC081-009.

This datatable is part of the Agronomic Yields dataset.

This dataset contains the yields from machine harvests for all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BCSE). Yields are measured in each treatment replicate (R1-R5) during normal crop harvest by machine harvesters appropriate to each crop, as recorded in the KBS Aglog.

This dataset also includes yields from two different subplot studies on 1) stover removal vs stover non-removal and 2) plus nitrogen vs no nitrogen fertilization. See the BCSE – Sampling protocol for further description of subplot management and location.

stover remains did the stover remain in the field? The standard practice was to remove stover in corn years and leave it in the stover_microplots. On the plot plans the stover microplots are called 'stover non-removal microplots'
