Maize-soybean intercropping: A bibliometric analysis of 30 years of research publications
AGRONOMY JOURNAL(2022)
摘要
Maize (Zea may L.)-soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize-soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the literature related to research in the field of maize-soybean intercropping, with the aim of studying keyword hotspots and evolving trends, and analyzing the future research directions. The results showed that the annual number of publications on maize-soybean intercropping showed rapid growth from 2010 to 2021. The top three publishing countries were China, the United States, and India, and the top three institutions were Sichuan Agricultural University, the Ministry of Agriculture and Rural Affairs of China, and China Agricultural University. Th three most popular journals were Field Crops Research, Agronomy Journal, and Indian Journal of Agronomy. Agronomy, multidisciplinary agriculture and plant science were the most popular research categories. A keyword analysis indicated that "maize" was the most popular study area. Crop root coupling processes, biological nitrogen fixation, efficient utilization of resources, carbon sequestration and emission reduction, microbial communities, and interspecific relationships are the current hot research topics. This study review and analyzed the current research hotspots and future research trends to provide an important reference for scientists to better respond to food security issues.
