Proceedings 2020

The Proceedings include three kinds of contributions:

Reviewed Papers

This part contains papers of scientific quality which were subject of a full anonymous peer review process. Each contribution was sent to at least two reviewers with expertise in the relevant field of study. The editorial decision of acceptance of a paper in the Conference and in the part “reviewed papers” of the Proceedings was done by the Conference Organisers based on the referees’ reports.

Short Contributions

This part of the Proceedings is reserved for smaller contributions. They were subject to an abbreviated reviewing process (only one reviewer, conclusions must not be based on trials over more years or locations).

Short Communications

Authors have the possibility to present a short communication (just a short summary of two pages, not reviewed) in the proceedings and to refer to an existing or ongoing publication elsewhere. If acceptance of this publication was not yet clear or the contribution was not yet submitted to a journal, the authors have the possibility to inform us about the citation after publication. In this case, the citation will be found on Ecofruit website as soon as available.
For a clear arrangement of the contributions they are listed following the order of the topics. The information about the kind of contribution can be found in the topline of the pages.
