WP 2: Multi-environment experiment (MEE)

The overall objective of this work package is to improve understanding and use of Cover crop / conservation agriculture systems under a broad range of environmental conditions and interactions with management techniques and farm technology. Specific objectives are:

• To provide the common experimental framework for part of WP 4 (Machinery), WP 5 (Assessment of soil ecological impact), WP 6 (Competition), and WP 7 (Phytopathology);

• to serve as a demonstration site for dissemination purposes in WP 1 (Dissemination and knowledge transfer);

• to supply information for the cover crop Toolbox in WP 8.

Different cover crop and mulch systems will be compared in the context of a series of coordinated field trials in different European and Mediterranean environments and on-going long-term experiments. A two-year sequence of wheat and a spring crop (maize, potatoes, or vegetables) is the common experimental base upon which to compare the different cover crop and mulch systems. In addition to the Multi-Environment Experiment, partners UNITUS, UNIPI-SSSA, and IAPAR are performing long-term experiments with rotations similar to that of the MEE. These experiments will be used to assess the long-term effects of subsidiary crop based minimum-tillage systems.

The Trials are being performed in 12 different Environments in Europe, Morocco and Brazil.

WP 2.3: Production costs of subsidiary crops

The following table lists an overview of costs for the cultivation of OSCAR subsidiary crops in conventional (CT), reduced tillage (RT) and no tillage (NT) systems in different trials and locations.

The additional costs for cultivation of subsidiary cropping systems contain variable and fixed machine costs, variable and fixed costs of labour as well as interest charge.
