AGROCIENCIA is a scientific journal founded in 1966 and sponsored by The Colegio de Postgraduados, a Mexican institution devoted to the Teaching, Research and Services in sciences. The editorial main scope is to elect pioneer scientific research papers in any field which meet a high standard to promote the journal reputation and scientific reliance in international databases. Papers which interest readers from more than one discipline are mostly considered. In particular, we are keen to publish works with international audiences. Through the years 2000 to 2006 AGROCIENCIA was a bimonthly journal, with all contributions published simultaneously in Spanish and English languages. Since 2007 it appears every month and a half (eight issues per year). The journal now expands the coverage area to all aspects of the life sciences including human sciences and technologies. AGROCIENCIA also publishes research notes and reports from expeditions, book reviews, and other materials of interest to the members of the editorial board. All contributions are peer reviewed.
