Intercropping has been practiced worldwide in both traditional and sustainable agriculture
to feed the growing population. This study aims to analyze the research status and evolution of
intercropping, to identify the influential authors, research centers, and articles, and to reveal the main
research topics between 1992 and 2020 based on the Web of Science Core Collection database. The
results show that the volume of publications in this field has increased rapidly over the past three
decades. The analysis identifies the top three authors (i.e., Meine Van Noordwijk, Wenyu Yang, and
Teja Tscharntke), top three contributing organizations (i.e., the World Agroforestry Center (ICRAF),
the Chinese Academy of Science, and the INRA), and three most productive countries (i.e., the USA,
India, and China). Co-occurrence analysis demonstrates that studies on intercropping can be divided
into four clusters as centered by keywords of intercropping/maize, biodiversity/conservation,
agroforestry, and carbon, respectively. Lal 2004 is the most influential study with the greatest number
of citations and Agroforestry Systems is the most utilized journal. Perspectives on future studies
were also given. This study helps researchers to clarify the current research status in the field of
intercropping and put forward its future research.
