Drought and sorghum: a bibliometric analysis using VOS viewer.

Drought has emerged as a significant global concern in recent years, leading to a proliferation of research on sorghum, an important drought resistant crop. Consequently, conducting a bibliometric analysis of said publications has the potential to yield insights into current areas of interest and potential avenues for future research. The present study utilized the Web of Science database to gather literature published between the years 2000 and 2022. The search terms 'drought' AND 'sorghum' was employed to identify relevant publications and as a result, 1731 publications were obtained. The bibliometric analysis of the obtained articles was conducted using VOSviewer software (1.6.19). The keyword 'sorghum' was found to have the highest frequency, with a total link strength of 4238. This keyword exhibited a strong association with the terms 'drought' and 'drought tolerance'. The average number of citations for the 100 most-cited articles was 509.2. The journal Crop Science attained the top position with 60 published articles and secured the highest number of citations with a count of 2795. The academic works of Graeme L. Hammer, comprising 40 articles affiliated with the University of Queensland (UQ), have garnered a total of 3612 citations. Similarly, the same university has produced 112 articles that have been cited 5551 times, thereby establishing it as the most frequently cited organization, with Hammer receiving the highest citation count. UQ had a total of 41 collaborators, with a cumulative link strength of 115. The USA has the highest number of articles pertaining to drought and sorghum. The published literature has focused on abiotic stress tolerance, genetic analysis, and physiological traits, among others. It is anticipated that there will be a substantial rise in the quantity of worldwide publications pertaining to drought and sorghum. The USA offered a significant contribution to this emerging field.Communicated by Ramaswamy H. Sarma.
