The main objective of this paper was to perform an overview analysis of academic publications about no-tillage. A bibliometric survey was conducted based on the most cited articles in Web of Science database. Thus, lexical and multiple correspondence analyses were performed with the most frequent words in title, abstract and keyword fields. The results suggest that there is a strong emphasis on no-tillage publications on environmental issues, such as carbon sequestration and greenhouse gas emissions.
