Table 2
Structure and order of magnitude of direct costs attributable to bird damage at emergence under two scenarios with or without resowing. Yield losses for both scenarios are estimated at 12% (Sausse, 2016).
| Cost source | Scenario | |
|---|---|---|
| Resowing | Without resowing | |
| Prevention | Equipment (scaring), time spent... Not rated | |
| Lower yield | Non-optimal planting date: €110 | Non-optimal population (density and structure): €129 |
| Price reduction on oil content | Not relevant | |
| Cost of re-sowing | Passage − seed: €119 | Not relevant |
| TOTAL (excluding prevention) | €229 | €129 |
