Nitrogen Fertilzer Subplot Yields — GLBRC Biofuel Cropping System Experiment
Data in the KBS GLBRC core database may not be published without written permission of the lead investigator or project director Full terms of use
Dry matter yields of the N fertilizer subplots (plus nitrogen vs no nitrogen) to examine the effects of N fertilizer on ecosystem processes in BCSE perennial (G4-G10, depending on year) and annual (G2-G3, depending on year) treatments. Note that the main plots of all treatments, except G10, are N-fertilized; the main plot of G10 is not N-fertilized.
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.
