Abstract

Abstract:

To address dietary zinc deficiency in populations dependent on wheat, publications related to wheat grain zinc and zinc fertilizers in the China National Knowledge Infrastructure (CNKI, 172 articles) and the Web of Science Core Collection (660 articles) from 1995 to 2024 were analyzed and visualized using CiteSpace and VOSviewer based on the bibliometric analysis. The study examined the top 10 contributing countries, institutions, and journals, as well as the top 10 most-cited publications and authors. Research hotspots were found by the keyword co-occurrence, cluster analysis, and timeline evolution, and international collaboration patterns were also identified. Results showed that English research focused on heavy metals and agronomic biofortification, whereas Chinese studies emphasized foliar zinc fertilization and grain quality. Timeline analysis revealed two phases in Chinese research: studies on grain quality, phytic acid, zinc concentration, and zinc speciation (2005-2016), followed by grain zinc uptake, novel zinc fertilizers, and zinc spray application methods(2016-2024). Similarly, English research early interested in wheat micronutrients, deficiency symptoms, nutrition, yield, and reproduction (1995-2015), and then concentrated on wheat zinc, zinc fertilizer application methods, yield enhancement, and reproduction (2016-2024). Pakistan, Australia, the United States, Canada, and Turkey were connected closely with China in the international collaboration network. From 1995 to 2024, global publication about wheat grain zinc was increased gradually, the publication and citation impact were obvious lead in Australia, the United States, China, and Pakistan. Although China produces a high number of publications in this field, it lacks high-impact, authoritative studies. Strengthening international research collaboration is efficiency to enhance the quality and influence for the future work.

Key words: wheat, grain Zn concentration, Zn fertilizer, bibliometric analysis, CiteSpace, VOSviewer
