Agronomic Yields — Biodiversity Gradient 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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 grain yields of corn, soybean, and wheat, at standard moisture, over the duration of the Biodiversity Gradient Experiment (2000-2019) and dry matter (0% moisture) yields of sorghum planted in 2020 to examine the experimental residual effects on crop production. Yields are measured before the regular harvest by harvesting a section within each plot with a plot combine.

This datatable is part of the Agronomy of the Biodiversity Gradient Experiment dataset.

This dataset contains the agronomic yields and activities of the LTER Biodiversity Gradient Experiment (a.k.a. Biodiversity Experiment Plots or BExP) from its establishment in 2000 through 2020, one year past its retirement when all treatment plots (B1-B21) were planted to sorghum to test for residual agronomic effects.
