Structuration and content of the knowledge-sharing phase.
Sections and objectives | Detailed explanations of the shared knowledge | Example of knowledge formalisation used during the presentation |
---|---|---|
Part 1: Multi-environment trial network Overview of the results of the various analysis performed with the experimental data collected in this experimental network |
– Evolution of weed biomass according to the treatments tested in each trial and consequences on the level of impurities in the harvested camelina. – Characterization of camelina yield variability and identification of the main factors explaining this variability (via an agronomic diagnosis). – Characterization of camelina seed quality (oil and fatty acid contents) and identification of the main factors explaining this variability (via an agronomic diagnosis). – Economic assessment: computation of the semi-net margin for each treatment using two scenarios of camelina selling prices. – Environmental assessment: estimation of the nitrate leaching (mg/l) for the different treatments in 2017 (via modelling with the LIXIM model1) and assumptions about the factors explaining the observed variability. |
![]() Linear relation between weed biomass and crop biomass at harvest, illustrated with some pictures took in the field to show differences in soil cover. |
Conclusion Part 1 Summary of the knowledge produced |
– Indicators used by the research team to assess camelina sown in spring (light green). – Relationships between agricultural practices (dark green), soil conditions (brown), plant characteristics (orange) and weather conditions (blue) influencing the assessment indicators. |
![]() Functional scheme obtained for the multi-environment trials network. |
Part 2: Farmer-experimenter’ trials Overview of the data extracted from the qualitative assessment performed by the farmers |
– Synthesis of success and failure factors mentioned by three farmers-experimenters for different modalities (M) of inclusion and management of camelina as double crop (interview analysis). – Summary of the farmer’s results from the factorial trial combining different seeding rates and mineral nitrogen rates with the presence or absence of tillage (interview analysis). |
![]() Formalization of the qualitative assessment performed by the farmers (level of satisfaction for the considered criteria and associated explanations). |
