Agronomic Yields of the Weed and Fertilizer Study — Main Cropping System Experiment (MCSE)

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use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, from the Weed and Fertlizer Study in MCSE Treatments 3 and 4 microplots.

This datatable is part of the Weed and Fertilizer Study in T3 and T4 dataset.

A microplot study was conducted in the Reduced input (T3) and Biologically based (T4) treatments of the LTER Main Cropping System Experiment (2006-2014) to examine the effect of weed control and fertilization on crop yields. Microplot treatments were a factorial combination of 3 weed control strategies and 2 fertilization levels for a total of 6 microplots, each 15 ft wide (E-W) by 50 ft long (N-S) and randomly assigned within a block in the northwest corner of each replicate (R1-R6). Weed control strategies included: Business as Usual (BAU, same weed control as the main T3 or T4 plots); Weed Free (no weeds allowed to become established); and No Weed Control (no form of weed control). Fertilizer was applied at two levels: Fertilized (same level as applied to the Conventional T1 main plots) and Unfertilized (no fertilizer applied).
