No global summary of maize endophyte publication exists. It's hard to elaborate on global data because the provided information is localized. This study aimed to analyze the progression of research on maize endophytes and their insight for the future. Six hundred-three papers related to the topic were downloaded from Scopus. Parameters were computed by Excel 2016, whereas bibliometric analysis used VOSviewer. Co-occurrence, co-authorship, and citation were the three primary types of analysis. Kolmogorov-Smirnov determined the author's Lotka's Law productivity. This study found that the cumulative number of publications followed a linear model from 1966 to 1991; however, later, the model followed an exponential curve. The most comprehensive research on maize endophytic topics is in Agricultural and Biological Sciences (34.3%). The US published 203 documents, followed by China (79) and Brazil (55). Bacon CW is the author with the most works published, 23 in total, followed by Hinton DN (17) and Raizada MN (15). Most of these papers concern endophytic bacteria like Paenibacillus, Burkholderia, and Bacillus. Triplett EW's research on diazotrophic endophytes was one of the topics that stimulated scientists' attention and was quoted 845 times. The author's productivity distribution doesn't follow Lotka's Law. Three clusters in the bibliometric map were found, including fungal, bacterial, and microbiology of endophytes. The result showed that the study on maize endophytic fungi was smaller than bacterial species. Enterobacter sp. and Bacillus sp. are the two most common bacterial endophytes studied, while Beauveria bassiana is the dominant fungal endophyte. Studies on microbiology and identification of endophytes, phylogenetic, biomolecular bacteria, and the role of endophytes as PGPRs are potential to be conducted. Finally, this paper can be utilized as a summary about the state of the art study on maize endophytes.
