Global overview of research on quality protein maize: A bibliometric perspective

The bibliometric analysis uses the citation count of an article to measure its impact on the scientific community, yet there is still no comprehensive summary of research undertaken on the nutrition aspects of maize crop via bibliometric analysis. We aimed to evaluate the situations and trends of the most cited articles in maize nutrition via bibliometric analysis and to provide scientists with a practical guide in assessing the most influential articles and countries working on this subject. The top-cited articles in maize nutrition were compiled using the Scopus Index database. The articles selected were evaluated for their number of citations, year of publication, country of origin, type of study, and others. The database had articles published between 1980 and 2020. There is an incremental increase in the number of publications on the maize nutrition front after the 1990s. The United States of America is leading the research front as well as international research collaboration on QPM, followed by India and China. Our research presents a historical perspective on the scientific growth of maize nutrition and the countries that significantly impacted the development and progress of the concerned research area.
