Evaluating the effects of cotton intercropping on cool‐season perennial forage persistence, forage mass, and nutritive value in the southeastern United States

This is digital research data corresponding to a published manuscript, Evaluating the effects of cotton intercropping on cool-season perennial forage persistence, forage mass, and nutritive value in the southeastern United States, in Agronomy Journal.
 
Integrated forage–row cropping systems provide important agronomic and economic benefits to producers. However, little attention has been given to incorporating forages into row crop systems unique to the southeastern United States. This study assessed the viability of intercropping cotton (Gossypium hirsutum L.) on perennial, cool-season legumes during the summer months in the Southeast Coastal Plain over two production years. Treatments included a weedy fallow, annual ryegrass (ARG; Lolium multiflorum Lam.) monoculture, a red clover (RC; Trifolium pratense L.) and white clover (WC; Trifolium repens L.) mixture, and a three-species mixture of ARG, RC, and WC. Plots were established in fall 2020 with forage grown until May 2021 and 2022,..., Data was collected over two years (October 2020 - October 2022) at the Clemson Pee Dee Research and Education Center near Florence, SC. Data was collected by field measurements of plant height, biomass accumulation, and species persistence and diversity, with laboratory assays conducted to collect plant nutritional composition. Forage nutrtitive value parameters and fiber content were conducted by a third-party laboratory (Dairy One LLC, Ithaca, NY)., , # Data from: Evaluating the effects of cotton intercropping on cool-season perennial forage persistence, forage mass, and nutritive value in the southeastern United States

This dataset was used to generate 3 figures and 5 tables in the publication, \"Evaluating the effects of cotton intercropping on cool-season perennial forage persistence, forage mass, and nutritive value in the southeastern United States\". All data was collected in Florence, South Carolina at the Clemson University Pee Dee Research and Education Center during 2021 and 2022.

\#Description of dataset and file structure

Data is presented in an Microsoft Excel Spreadsheet, with separate tabs for datasets related to each of the 3 figures/subfigures and 5 tables in the published manuscript.

For all data the following treatment abbreviations are used:

Fallow = weedy, unplanted treatment
ARG = annual ryegrass
RC+WC = 50/50 mixture of red and white clover
ARG+RC+WC = 50% annual ryegrass, 25% red clover, and 25% white clove...

本数据集为发表于《农学杂志》（Agronomy Journal）的论文《美国东南部棉花间作（cotton intercropping）对冷季多年生牧草（cool-season perennial forage）持久性、产量及营养价值的影响评估》所对应的数字化研究数据。

牧草-行作物一体化间作系统（Integrated forage–row cropping systems）可为生产者带来重要的农艺与经济效益。然而，针对美国东南部独特行作物系统中牧草整合的研究关注较少。本研究评估了两年生产周期内，美国东南沿海平原（Southeast Coastal Plain）夏季棉花（Gossypium hirsutum L.）与多年生冷季豆科牧草间作的可行性。处理组包括杂草休耕（weedy fallow）、一年生黑麦草（ARG；Lolium multiflorum Lam.）单作、红三叶（RC；Trifolium pratense L.）与白三叶（WC；Trifolium repens L.）混作，以及ARG、RC与WC的三物种混作。试验小区于2020年秋季建立，牧草生长至2021年及2022年5月……数据采集周期为两年（2020年10月-2022年10月），地点位于南卡罗来纳州弗洛伦斯市附近的克莱姆森大学Pee Dee研究与教育中心（Clemson Pee Dee Research and Education Center）。数据通过株高、生物量积累及物种持久性与多样性的田间测量（field measurements）获取，并通过实验室分析（laboratory assays）测定植物营养成分。牧草营养价值参数及纤维含量由第三方实验室（纽约州伊萨卡市Dairy One LLC）检测。
