摘要
文献计量分析探索大量科学数据,揭示特定研究领域的趋势和见解。我们使用 Scopus 数据库和 VOSviewer 对美国玉米(Zea mays L.)生产进行了 30 年(1990-2020 年)的文献计量分析。在文章标题、摘要和表明玉米管理方法的关键词范围内进行了搜索查询。根据主题领域和期刊的排除标准,共检索到 7468 篇出版物。数据分析显示,共有 7327 位作者和 47 个组织在 69 种期刊上发表了文章。调查中排名前五位的机构是美国农业部农业研究服务局、爱荷华州立大学、内布拉斯加大学、伊利诺伊大学和普渡大学。最多产的作者是 Rattan Lal 博士(俄亥俄州立大学,俄亥俄州哥伦布市)、Douglas L. Karlen 博士(美国农业部-农业研究服务局,爱荷华州艾姆斯市)、Kenneth G. Cassman 博士(内布拉斯加大学,内布拉斯加州林肯市)、Lajpat Rai Ahuja 博士(美国农业部-农业研究服务局,科罗拉多州柯林斯堡市)和 John Walsh Doran 博士(美国农业部-农业研究服务局,内布拉斯加州林肯市)。发表论文最多的期刊是《农学杂志》、《美国土壤科学学会杂志》、《土壤与耕作研究》、《作物科学》和《农业、生态系统与环境》。此外,作者关键词与查询关键词不同,免耕、氮、覆盖作物、大豆、灌溉、磷、保护性耕作、产量和水质最为突出。此外,在 1998 年至 2020 年期间,关键词有明显的变化,并有观察到的趋势。总之,这些发现使研究人员能够通过论文中的超链接探索网络地图,找出研究空白,推进原创研究,弥补文献空白。
Bibliometric analysis of management practices in US corn (1990–2020)
Bibliometric analysis explores large volume of scientific data, revealing trends and insights in a specific research field. Consistently, a bibliometric analysis of 30 years (1990–2020) was performed within the US corn (Zea mays L.) production using the Scopus database and VOSviewer. Search query was performed within the article title, abstract, and keywords indicative of management practices in corn. Exclusion criterion based on subject area and journals generated a total of 7468 publications. The data analysis revealed contributions from 7327 authors and 47 organizations documented in 69 journals. The top five organizations leading the investigation were United States Department of Agriculture – Agricultural Research Service, Iowa State University, University of Nebraska, University of Illinois, and Purdue University. The most prolific authors were Dr. Rattan Lal (Ohio State University, Columbus, OH), Dr. Douglas L. Karlen (USDA-ARS, Ames, IA), Dr. Kenneth G. Cassman (University of Nebraska, Lincoln, NE), Dr. Lajpat Rai Ahuja (USDA-ARS, Ft. Collins, CO), and Dr. John Walsh Doran (USDA-ARS, Lincoln, NE). Journals with most publications were Agronomy Journal; Soil Science Society of America Journal; Soil and Tillage Research; Crop Science; and Agriculture, Ecosystems & Environment. Furthermore, author keywords differed from queried keywords, and no-till, nitrogen, cover crop, soybean, irrigation, phosphorus, conservation tillage, yield, and water quality were most prominent. Moreover, there was an evident shift in keywords and an observed trend between 1998 and 2020. Overall, these findings allow researchers to explore network maps via the hyperlinks present in papers, identifying research gaps and advancing original studies to bridge gaps in the literature.
