Meta-analyses and their application in agriculture: a case study on variety mixtures of cereals

Ph.d. project evaluating the advantages of mixed cultivation of several varieties of a single crop for sustainable agricultural production using meta-analyses techniques.

 
Mixed cultivation of several varieties of a single crop is a promising contribution to a more effective and sustainable agricultural production (e.g. the BAR-OF project). Like field trials in general, it is practically impossible to control all environmental parameters in single field evaluations of variety mixtures, and information on general relationships and factors of importance for the successful application of variety mixtures may be overlooked. The primary objectives of the project are (1) to use meta-analysis, a statistical technique that enables evaluation of research results across different studies, to obtain such types of information and (2) to adapt meta-analysis methodology to agronomic research. The project is collaborating closely with researchers involved in the SUSVAR network.

Participants:
The Royal Veterinary and Agricultural University, Denmark, and SOAR, the Research School for Organic Agriculture and Food Systems.

Employee:
Lars B Kiær (PhD student) Supervisors are Hanne Østergård, Risø DTU, and Ib Skovgaard, The Royal Veterinary and Agricultural University.
The project is co-funded by Risø DTU
