Table 1.
Model performance of Random Forest models trained using observations from each agro-management treatment from row spacing and seeding density studies.
| Study | Treatment | OOB Training | Testing | ||
|---|---|---|---|---|---|
| RMSE | R2 | RMSE | R2 | ||
| IA-RS | 38 cm | 328.2 | 0.57 | 222.6 | 0.53 |
| 76 cm | 334.8 | 0.50 | 204.9 | 0.50 | |
| IA-SD | Low (124,000 plants/ha) | 232.7 | 0.83 | 185.3 | 0.82 |
| Med (346,000 plants/ha) | 303.9 | 0.71 | 241.1 | 0.69 | |
| High (568,000 plants/ha) | 299.7 | 0.71 | 209.4 | 0.74 | |
OOB = Out of Bag, RMSE = Root Mean Square Error. IA-RS = row spacing study. IA-SD = seeding density study.
