Editorial Process


Siembra uses the Open Journal Systems (OJS) as its editorial management system, developed by the Public Knowledge Project (PKP). All manuscripts to be considered for publication must be submitted through this system.

Manuscripts should be submitted fulfilling the issues stated at the "Guide for Authors", The reception of manuscripts does not imply in any way a commitment of publication by the journal. Authors are responsible for including complete and correct information about the manuscript and its authors in the Metadata section.

Authors must include their ORCID iDs to encourage standardized criteria for authorship. If you do not have this iD, you can obtain it free of charge at: 

Initially, the manuscripts will be received by a member of the Editorial Board, who will review manuscripts complies with the aim and scope of Siembra, as well as the journal's guidelines and the minimum quality criteria in terms of writing and content. This review will verify the level of originality by using specialized software (URKUND, Unicheck) and existing digital resources for this purpose.

If manuscript complies with general conditions, it will be sent, in the second instance, to external reviewers, national and international, to the Faculty of Agricultural Sciences, Central University of Ecuador, who will review according to criteria of relevance, currency and relevance, quality, clarity of expression and organization, and originality of the data included in the manuscript. The reviewers will recommend its:

  • Rejection
  • Major revisions
  • Publication with minor revisions
  • Publication without review

The authors will receive the reports of the scientific reviews anonymously. Once the manuscripts with corrections are received, they will be reviewed again by the external reviewers. We recommend to the authors the submission of their comments to the reviewers along with the revised manuscript, indicating the changes made and/or the aspects they consider not relevant to the observations made by the reviewers.
