Maize (Zea mays L.) plays a critical role in global food, feed, and biofuel security; however, its productivity is increasingly threatened by drought stress, climate change, and freshwater scarcity.This study aimed to provide a comprehensive bibliometric and scientific assessment of global research trends on drought stress in maize from 1984 to 2026 and to identify major physiological, molecular, and technological strategies to improve drought resilience.Bibliometric data were collected from the Web of Science Core Collection using drought-and maize-related keywords.A total of 2860 publications were identified, from which 853 highly relevant papers for maize were selected for detailed analysis.The datasets were analyzed using VOSviewer to evaluate publication trends, keyword co-occurrence, institutional collaboration, country networks, journals, and publisher contributions.The results revealed a substantial increase in research output after 2019, with the highest annual number of publications recorded in 2024.
