The main objectives of the present study to find out the modified collaboration coefficient and authorship pattern of the journal of agricultural extension during the period (2008–2017). The study examined and analysed various patterns using different formulas like RGR, Dt., CC, MCC, CAI etc. The highest 15.51% of publications were contributed in the year 2017 while the minimum 6.93% of articles were published in the starting year i.e. 2008. The maximum RGR and Dt were 0.739 and 7.766 recorded in the year 2008 and 2015 respectively. The average MCC was 0.58 while the CI was 2.96 recorded during the period of study. The highest 274 publications were contributed by multiple authors, while only 29 articles were contributed by a single author from the marked period of study.
