Effect of the generalization and the proper use of Decision Support Systems (DSS), of legume as a preceding crop or of intercropping frost-sensitive legumes on greenhouse gas emissions (GHG), seed yields of oilseed rape and nitrogen applications.
| Mean value from 2012/2013 to 2016/2017 | Generalization and proper use of DSS | Legume as a preceding crop | Intercropping frost-sensitive legumes | |
|---|---|---|---|---|
| GHG of oilseed rape (g CO2 eq. MJ−1) | 30.1 | 27.7 | 25.0 | 26.4 |
| GHG of biodiesel (g CO2 eq. MJ−1) | 38.7 | 36.2 | 33.6 | 35.0 |
| Seed yield (t ha−1) | 3.69 | 3.55 | 3.71 | 3.69 |
| Mineral nitrogen application (kg N ha−1) | 160.6 | 133.6 | 119.6 | 130.6 |
| Organic nitrogen application (kg N ha−1) | 38.5 | 38.5 | 38.5 | 38.5 |
