Morrow Plots Treatment and Yield Data

The Morrow Plots at the University of Illinois at Urbana-Champaign are the longest-running continuous experimental plots in the Americas. In continuous operation since 1876, the plots were established to explore the impact of crop rotation and soil treatment on corn crop yields. In 2018, The Morrow Plots Data Curation Working Group began to identify, collect and curate the various data records created over the history of the experiment. The resulting data table published here includes planting, treatment and yield data for the Morrow Plots since 1888. Please see the included codebook for a detailed explanation of the data sources and their content. This dataset will be updated as new yield data becomes available. *NOTE: While digitized and accessed through IDEALS, the physical copy of the field notebook: <a href="https://archon.library.illinois.edu/archives/index.php?p=collections/controlcard&id=11846">Morrow Plots Notebook, 1876-1913, 1967</a> is also held at the University of Illinois Archives.

伊利诺伊大学香槟分校的莫罗试验地是美国持续运行时间最长的实验田地。自1876年连续运营以来，这些试验田的设立旨在探究作物轮作和土壤处理对玉米产量的影响。2018年，莫罗试验地数据整理工作组开始识别、收集和整理实验历史上的各种数据记录。在此发布的成果数据表中包含了自1888年以来的莫罗试验地的种植、处理和产量数据。请参阅附带的代码簿，以获取数据来源及其内容的详细解释。随着新产量数据的可用，该数据集将进行更新。*备注：尽管通过IDEALS进行数字化并可访问，但该试验地的物理笔记本副本（<a href="https://archon.library.illinois.edu/archives/index.php?p=collections/controlcard&id=11846">莫罗试验地笔记本，1876-1913，1967</a>）亦存放在伊利诺伊大学档案馆。*
